Jenny Wren - Troglodytes troglodytes

Jenny Wren - Troglodytes troglodytes


There is something valiant about Jenny,  Kitty-me-wren or Our Lady's Hen.  She is our most common breeding bird, a little bird of the earth that stalks us on our walks around the garden.  She never flies very high, we catch occasional glimpses of her skulking out of sight, poking about in holes and peering under things, disappearing and reappearing in amongst the tree roots and in the bramble patches. The male Wren will build up to eight nests to attract his bride to be, and he is amongst the first up in the morning to guard his territory with a loud clear voice that is amongst the most complex in the bird kingdom.  They are tiny, they are everywhere except wide open spaces, but we still find them  in scrub on remote barren islands.

We have forgotten that the wren was once the central object of worship not just in Britain but in every European nation.  In Ireland they have medieval manuscripts telling us how to read the speech of the wren.  The Welsh called them "Dryw", which is also their word for druid and soothsayer, because this bird was sacred to the druids, it is thought they were kept in cages as oracles.    The English word Wren is derived from Drian, ie Draoi-en, "The Druid's Bird" (from the proto-Celtic Drevo, cognate with the English "true").

Her nobility was ambiguous and had many forms, she was a symbol of the earth that sometimes usurped the Eagle, the sun and rightful "the king of the birds".  In the Mabinogion, an ancient Welsh masterpiece, a hero called Llew who slays wrens is slain himself.  His body is transformed into an Eagle with the wren on its back, just as one year runs into the next.  Thus we find this symbolism that the wren is the spirit of the the earth, the old year killed at the winter solstice and reborn again to soar like the Sun and the Eagle into the coming Spring.  In many Celtic communities  they had wren hunts at the Winter solstice and afterwards they paraded their little bodies on sticks around villages, exchanging their feathers for tokens. In parts of France they would dress her in the apparel of hawks,

The earliest stories of her trickery are 4000 years old and come from Sumeria, they tell of a wren who outwitted an elephant.   Aesop (600 BCE) is the earliest credited source of the a fable about a congress of birds which had gathered to choose their king, and to this end they had organised a competition to find the bird that could fly the highest.   Of course the Eagle soured higher than any other bird could manage, and so the confident Eagle looked down and said "look I am your King".  Suddenly, the little wren, who had hidden himself in the feather's of the Eagles crest, flew a few inches higher and chirped "Birds look up and behold your King". Across Europe abundant variants and sequels of these stories survive, they are found in the Brothers Grimm and Shakespeare, stories of angry birds and blundering owls who Jenny always outwitted, but sometimes paying a price; she lost half her tail when the Eagle in his rage slammed her to the ground and was forever banned by the other birds from ever flying higher than the Hawthorn bush.


Her kingship is celebrated across Europe in her name; the latin word for wren is Regulus; Greek  Basiliskos (Little King); French Roilet (Little King) and Roi de froidure (Cold Weather King); Italian Reatino (Little King); Swedish Kungs Fogel (Kings Fowl); Danish Elle-Konge (Alder King); Dutch Konji (King) and Winter-koninkje (Little Winter King); German Zaunkonig (Hedge King) and Schneekonig (Snow King). To this day the Bretons have a proverb "The Eagle flees before the Wren". 


Amongst the many names from around the British Isles are: Kitty-me-wren, Wran, Wrannock, Cutty, Cuddy, Scut, Scutty, Stumpy Dick, Cracket, Carckadee, Tit wren, Tom Thumb and St Mary's Hen and Little Brown Nut (Shetlands)

The House Sparrow - Passer domesticus

The Gregarious House Sparrows Passer domesticus


My Grandfather used to call them Spadgers. The male can be recognised by his black bib and more vivid markings. Local British names include sparrow, sparr, sparrer, spadger, spadgick , spug, Spuggies, spur or Sprig (Scotland)  Spatzie or Spotsie (N America)  from the German Spatz which has a common etymological root with speed 

House Sparrows, as their name implies, are rarely seen far from human habitation.  It is thought that they are descendent from weaver finches that cohabited with stone age people on the fringes of the Mediterranean.  A clever adaptation because ever since they have co-evolved with us and followed our species around the world, today they are the most widely distributed birds on the planet.  In recent years the British population has declined dramatically, this might be because our houses have less nesting nooks and crannies and we are better at recycling our waste and protecting our grain on our farmsteads.

Such strong associations generates rich traditions and myths; the ancient Greeks associated sparrows with Aphrodite, Goddess of Love.  Cattalus Lesbia, a famous Roman poem, used a pet sparrow as a symbol of true love and spiritual connection, but during the medieval age this idea had degenerated into seeing sparrows as lustful, as is echoed by later writers such as Chaucer and Shakespeare.

In the bible Jesus says "Are not five sparrows sold for two farthings, and not one of them is forgotten before God?"  These themes about the sparrows intrinsic value and chirpy good nature, their social pluckiness and speed are constantly resurrected, reinvented and transferred into new popular metaphors, like those surrounding the melting pot communities in the East End of London in the 1950s who identified themselves as "Cockney Sparrers", and later inspired a punk band of that name.

The Sparrow

Catullus Lesbea's Sparrow

All you Loves and Cupids cry
and all you men of feeling
my girl’s sparrow is dead,
my girl’s beloved sparrow.
She loved him more than herself.
He was sweeter than honey, and he
knew her, as she knows her mother.
He never flew out of her lap,
but, hopping about here and there,
just chirped to his lady, alone.
Now he is flying the dark
no one ever returns from.
Evil to you, evil Shades
of Orcus, destroyers of beauty.
You have stolen the beautiful sparrow from me.
Oh sad day! Oh poor little sparrow!
Because of you my sweet girl’s eyes
are red with weeping, and swollen.

The Mute Swan - Cynus olor

British Birds :  The Mute Swan Cynus olor



Mute swans, the commonest swan native to Northern Europe, are easily identified by the black knob atop their orange beaks.  Swans pair for life and return to the same nest every year which they defend by hissing aggressively and chasing away intruders, otherwise except for the odd grunt and hoarse whistle, they are mute as the name suggests, .  I always imagined Swan was a homophone of watery words like Swim, Swiss and Splash, but I was wrong.  Swan is derived from an Old Saxon word swan or suan, (Danish svane, Dutch zwaan, German schwan, Icelandic svanr and Swedish svan) which has its root Indo-European *swen or *swon (to sound, to sing).   Thus "Mute Swan" encapsulates an image of the bird as mute singer.

Aesop, 6th century BCE, has two fables mentioning mute swans that would only sing under duress, especially after they had been threatened with death, and then they sang beautifully. Hence the phrase Swan Song meaning something we do at the end of our careers before we retire or die.  It seems that these ancient stories about reluctant (mute) singing swans are very old.  Looking on Google it seems to me that there is compelling evidence to suggest that ancient cultures mentally matched the necks of swans with the shape of their bronze age trumpets called lures (lurs).  

Danish Bronze-Age Lur; 13th-5th Century B.C. (Wikipedia)



These lurs appear on Scandinavian rock carving from 1000 BCE.  


 
 Norse rock carvings with swan necked lures  


The Celts, who appear a few hundred years later, used to carry lur like trumpets with animal heads into battle.

Celtic Lur

Although Celtic lurs with swan heads have not been found there is one Celtic helmet that looks like a lur with swan's head.

An Gallic Iron Age helmet in the shape of a swan (wikipedia)



Is this the song of the Swan?




In Roman times, after the Celts had been defeated, Pliny seems quite angry about the stories of singing swans, in his Natural Historie he tells us  "some say swans sing a mournful song before they die, but this is false, judging from experience. Swans are cannibals,and eat one another's flesh."

But Pliny's words fell on deaf ears, 500 years later Isidore of Serville is still telling stories that swans "singing is sweet because it has a long, curving neck".  Another 500 years later Bartholomaeus Angelicus is again mentioning that swans "hath a long neck diversely bent to make divers notes" and adding news about a fabulous country where "it is said that, in the countries that are called Hyperborean, the harpers harping before, the swans' birds fly out of their nests and sing full merrily"

A millennium later the meme connecting swans, death and beauty (this time dancing for salvation rather than singing) was still being promoted by classical ballet; most famously in the solo piece “The Dying Swan” and again in the final act of Swan Lake where a swan maiden dies to release herself from the curse of the evil Von Rothbart.
On a more optimistic note swans are symbols of flourishing beauty, most famously in the tale of the ugly duckling that unknowingly grows into a beautiful swan.  A particularly lovely idea can be found in Indian Mythology where swans are symbols of unworldly, untouchable beauty because when you put their feathers into water they remain dry and do not absorb water.

Aesop's Fables [6th century BCE] ( Temple 173): A man kept a swan for its voice and a goose for the table. Wanting to eat the goose, the man went out in the dark to get it, but caught the swan by mistake. The swan, thinking it was about to die, began to sing, and was recognized by its voice. (Temple 174): A man bought a swan because it was reputed to have a fine voice. One day, to provide entertainment at a feast, he urged the swan to sing, but it would not. Later, relizing it was about to die, the swan began to sing. His owner said "It was foolish of me to ask you to sing; I should have prepared to kill you, and then you would have sung!"
Pliny the Elder [1st century CE] (Natural History, Book 10, 32): Some say swans sing a mournful song before they die, but this (says Pliny) is false, judging from experience. Swans are cannibals, and eat one another's flesh.
Isidore of Seville [7th century CE] (Etymologies, Book 12, 7:18-19): There are two kinds of swan: one has all white feathers and is called olor the other is black and is called cygnus, though this one is not mentioned by the ancients. The cygnus is named from its singing (canendo) because it pours out song with modulated sounds. Its singing is sweet because it has a long, curving neck and its voice, in struggling to get out through the winding way, necessarily emits various notes. Some say that many swans gather and join in with song when the cithra is played in the Hyperborean regions. Sailors say that the swan is a good omen.
Bartholomaeus Anglicus [13th century CE] (De proprietatibus rerum, book 12): The swan feigneth sweetness of sweet songs with accord of voice, and he singeth sweetly for he hath a long neck diversely bent to make divers notes. And it is said that, in the countries that are called Hyperborean, the harpers harping before, the swans' birds fly out of their nests and sing full merrily. Shipmen trow that it tokeneth good if they meet swans in peril of shipwreck. Always the swan is the most merriest bird in divinations. Shipmen desire this bird for he dippeth not down in the waves. When the swan is in love he seeketh the female, and pleaseth her with beclipping of the neck, and draweth her to him-ward; and he joineth his neck to the female's neck, as it were binding the necks together.

The Blue Tit - Cyanistes caeruleus

The Blue Tit on Acer  Cyanistes caeruleus





Blue tits, well known for their love of collecting peanuts from the winter bird table, time their breeding cycle to coincide with the feast of green caterpillars found on young Oak leaves in May. During the summer months the parents can be seen hanging upside down inspecting the underside of leaves for small grubs, spiders and aphids on which they love to feed.  Later in the year they support themselves on berries and seeds and return to the bird tables.
The most common English name Blue Titmice is of 7th century Norse origin: ttr = small and Mase = bird which together translates as "small blue birds".  Other common names include  Blue Cap, Blue Bonnet, Blue Ox-eye, Blue Spick (N Devon), Nun, Tree Babbler (Cornwall), Pinchem (Bedfordshire), Tinnock, Yaup, Bee Bird (Hampshire), Willow Biter, Billy Biter (Midlands), Pickcheese (Norfolk), Tom Tit, Hickmall, Heckymal and Titmal (West Country).

The Robin - Turdus migratorius

The Robin  Turdus migratorius

There is nothing bashful about the Robin with their loud red breasts, loud melodic singing voices and bold opportunistic habit of following us around to cash in on the insects and worms we expose as we walk through
patches of rotting leaves or dig our gardens with our spades, they can become extremely tame and some will feed from the hand.  In medieval times it was popular to give birds human names as in Jack Daw and Jenny Wren.  Robin was originally a diminutive of Robert, but Chaucer called them "Tame Rudducks" which is perhaps an older name.  Other common names include Bob Robin, Bobbies, Ploughman's Bird, Robinet and Robin Ruck.  

There are many stories about how the Robin got a red breast; one is that it was scorched whilst fetching water for the souls of purgatory which is why the Welsh call Robins Brou-rhuddyn (Burnt Breast).  Another legend has it that the Robin’s breast became stained red with blood of Christ whilst it sang to ease his pain on the cross, but this is not the reason why the bird occurs on our Christmas cards.   The birds traditional place on Christmas cards started in Victorian times when there was a tradition that the postman would deliver your Christmas cards on Christmas day.  The postmen wore red jackets and were nicknamed Robin Redbreasts.

Long Tailed Titmice - Aegithalos caudatus

Long Tailed Titmice  Aegithalos caudatus


Long Tailed Tit (mice) are amongst our smallest birds.  They use their tails as a counter-balance as they seesaw and flit–tumble from branch to branch.  In winter large family groups come to our gardens announcing their arrival with high-pitched, rolling calls of “si-si-si-si-si" and a distinctive trilled ‘tsirrup: Once you’ve learnt to recognise their call you will always know a flock of long-tailed tits are in the vicinity.

When Spring arrives they pair off to build nest coccoons of wool and moss bound and felted together with spiders webs, lined with feathers and camouflaged with lichen flakes.  Inside a single female will lay up to 15 eggs.  When broods fail, as often happens, the parents move on to help their brothers and sisters raise their extended families of nephews and nieces.

There was a time when every English village would have had its own name for these birds.  Some traditions referred to their appearance:  Long Toms,
 Long-tailed Muffins (Worcestershire), Hedge Mumruffins, Bush Tits,  Kitty Long-tails,  Fluffits and Juffits,  Feather Pokes, Long-tailed Magsor and Millithrums (Miller’s Thumbs).  The other tradition was to describe their nests;  Oven Birds, Oven Builders (Lothian) and Bush Ovens (Norfolk), Barrel or Bottle Tits (Berkshire)  and Bum Barrels (Nottingham)

The Bullfinch - Pyrrhula pyrrhula


The Bullfinch Pyrrhula pyrrhula





The Bull Finch’s voluptuous pink breast and white rump make it one of the easiest birds to identify, but for many birdwatchers its call, a low mew, is often the first signs of bullfinches being present. They feed voraciously  on the buds of fruit trees in orchards which why they are sometimes called Bud Finch, Plum Birds or Bud Pickers (Devon).  There is a theory that the name Bull Finch may be a shortening of Bullace Finch. (Bullace being the Tudor name for the wild plum trees that were cultivated in medieval orchards).

The more widely believed theory is that Bullfinch got its name from its large thick head and stocky form, as happened with bull dog and bull frog.  Some birdwatchers claim to have seen the birds head-butt other finches off the bird table.  Other folk names include Alpe, Nope, Pope and Monk.

The Goldfinch - Carduelis carduelis






"Charms" of Goldfinch will often be seen feeding in meadows on thistledown and teasel.  This love of prickly plants has led to the birds being associated with Christ’s Passion.  The story goes
that a goldfinch flew down to the cross and pulled a thorn from Christ’s brow leaving the bird’s faces splashed with the blood of Christ.  In medieval pictures Goldfinch are often placed with the Madonna and child, sometimes the goldfinches are in Christ’s hands forewarning us of the crucifixion.  The birds are also seen next to John the Baptist and Saint Jerome.  Other common names are Saviour Birds, Thistle Tweakers and Thistle Finch. (There must be many other names for these very distinctive birds)

In the 19th century Goldfinches were were caged like canaries and renowned for their beauty and pretty song.

The Intelligence of Grass: Part 1

The Intelligence of Grass

Part One

The Making of Intelligence



The Church of La Sainte Chapelle

If you ever visit Paris you should take a trip to the light-filled church of La Sainte Chapelle which is a marvel of the flamboyant (Rayonnant) style of  Gothic architecture.
 
La Sainte-Chapelle in Paris

When you stand in the centre of the church you will experience a sense height, weightlessness and colour.  The Master Builder in charge of the construction probably worked from simple plans and personal experience with a team that would have been made up of illiterate carpenters, stone masons, craftspeople and their apprentices.   It is extraordinary to think the church. which was completed in 1248, is held up by the downward forces of gravity.  The masons who built this church knew how to control the thrust and counter thrust of the gravitational forces passing through the stones of the building, with this knowledge they channelled the downward thrust of the huge weight of the stone vaulted roof on a journey round the curved stone ribs of the ceiling arches to the heads of slim elegant pillars.  The carriage of the weight at the top of the pillars is supported by external flying buttresses that keep the pillars from splaying outwards.


This fragile church has stood in elegant stability for nearly 800 years ago.   The irony is that the lively illusion of lift we admire so much is held in place by the huge compression from the roof on the inert stones walls below. 

Gothic Architecture and the Cult of the Sun 

Gothic master builders honed their knowledge and designs over centuries.  Their building techniques were tested by trial and error that was passed down the generations, each new generation being driven by the desire of medieval Christians to fill their churches with ever more natural light.

Christianity was not alone in believing light has spiritual meaning, but the development of Christian theology of light is an eccentric and interesting story.  In the old testament God reveals himself to Moses as a burning bush but it is in the New Testament that the notion that "God is Light" becomes of central importance to Christianity.  In the Gospel according to St John Jesus tells us that "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life." John 8:12. American Standard Bible 

From the start the Roman and Jewish authorities saw the beliefs of the early church as subversive and threatening. When Pontius Pilate tried to quench the flames of belief in early Christians by crucifying Jesus he only succeeded in driving his followers into the darkness of windowless basement churches where the early Christian communities worshipped "the light of the world".  Just 64 years after Jesus' death the Christians were being blamed by Nero for the burning of Rome. 

Chapel of Saint Ananias, Damascus, Syria, 1st century
No amount of persecution stopped the spread of Christianity which became popular amongst the Roman Soldiers, and in 312 CE Emperor Constantine I seized control of the Roman Empire at the Battle of Milvian Bridge under the Christian banner.  Constantine was an ambitious and pragmatic man who transformed Christianity from being a marginalised, disparate and sometimes fractious underground sect into one of the official religions of Empire.

The spread of Christianity across the Roman Empire

The Churches new status as an official religion of State enabled Christians to move out from their dark basements to take over the old temples of Mithras.  Some of today's churches, like the Basilica of San Clement (rebuilt 1100), still have foundations that sit on the remains of Mithric Temples.

The Basilica of San Clement, Rome (rebuilt in 1100)


 
Remains of Mithric temple under St Clements

A short time after Constantine's death there lived a scholarly monk called Jerome (347-420)

St Jerome, Painting by Niccolò Antonio Colantonio.

(St Jerome  translated the bible from Hebrew into Latin)

The natural light coming through the windows of the Roman churches delighted  Jerome.  He even mentions knowing the Church of St Clements on which the Basilica of San Clement (above) was later built.  We can sense St Jeromes trauma when he wrote " Often I would find myself entering those crypts, deep dug in the earth, with the walls on either side lined with the bodies of the dead....Here and there the light, not entering the windows, but filtering down through shafts, relieved the horror of the darkness...black night closed around and there came to mind the line of Vergil " Horror ubique animos, simul ipsa silenta terrent" (everywhere horror seizes the soul and the very silence is dreadful)
 
The new buildings inherited and built for the early church were Romanesque, an architectural era that spans from the decline of the Roman empire to the beginnings of the medieval Gothic traditions.  Romanesque churches have rounded Roman (Norman) arches similar to the style the Romans used for their aqueducts.  The churches have tall narrow naves, stocky pillars and thick walls that are supported from the outside by substantial external buttresses.  The narrow distances between pillars leave limited space for windows through which the natural light of God arrives and floods the place of worship.
Basilica Saint Sernin (Toulouse 12th Century)



After enduring years of worshipping in darkness the early Christians became obsessed about letting more and more of God's light to enter the naves of their churches.  This need became a driving force that led to the development of the Gothic style of architecture

The Evolution of Gothic Architecture

We know we will never squash a stone







but a sharp hit with a mallet on the same slab will crack the stone




this is why a slab of stone used as a beam for a bridge will break under the quite light thumping of traffic.






In ancient Greece they placed short and stubby lintels on top of unsquashable tall pillars. The builders knew that it would be dangerous to have longer lintels, so the space between the pillars was always quite narrow.

Remains of Temple of Olympian Zeus Athens
The Roman genius was to realise that stone arches can be strung together in lines to create long, strong, free-standing load bearing bridges that would not crack under heavy traffic and could be used as aqueducts across wide ravines

Aqueduct Near Nerja, Spain

Arches arranged in a line are load-bearing but when the same weight is put on the centre of a free standing arch the lateral forces push the heads of the supporting pillars apart!


Free standing arches are only load bearing when the heads of the pillars are prevented from splaying apart with buttresses.  Arched entrances in walls can be higher and wider than doors with lintels which is why the arch became a symbol of imperial majesty through which victorious armies marched after returning from their campaigns abroad. 




The Romans built many free-standing Triumphal Arches, these were always built between wide buttresses on each side.  The is a typical Romans arch with rounded top and side doors.
 
Ancient_Roman_triumphal_arch_of_Medinaceli-Spain

Gothic Arches and Flying Buttress

A novelty of Gothic architecture was the development of pointed arches; pointed arches have less lateral thrust at the heads of the supporting pillars. 
 

Gothic arches could be made taller and wider than rounded arches, however the tops of the pillars still needed buttressing. The reduced lateral forces were absorbed through curved half arches called flying buttresses.  The ceilings of late Gothic Cathedrals are a web of intersecting stone arches, called ribs, which provided the structural strength.  In-between the ribs they used lighter thinner stone.  The lighter the roofs the broader the ceiling arches could be; the nave of York minster is 30 metres wide

King's College Chapel, Cambridge, is amongst the last of the late Gothic churches built  The wall space between the pillars is filled with filigree stonework that support huge stained glass windows.  During the daytime services "the true light of God" floods into the nave and over the congregation, St Jerome would have loved it.
  

King's College Chapel Cambridge during the day- no need for artificial light!


Gothic architecture is a good example of how technological evolution responds to narrowly specified cultural demands.   Late Gothic churches, such as Kings College Chapel in Cambridge, represents a paradigm of technical know-how that had been gathered and passed down by generations of builders.  The enduring stability of their elaborate stone piling techniques was achieved by using the gravity of a few keystones to lock every last stone permanently into place. Whenever we look at evolution, both technological and Darwinian, we come across this balancing act between refined fragile structures that are as delicate as a house of cards and the strength factor, where environmental factors threatens the stability of the house of cards.  Every evolutionary process meets a point where further evolution is constrained by the harshness of the environment, in a world without wind or subsidence the Gothic architects might have felt confident to build even more fragile cathedrals.

Kings College is a brittle, light filled structure that would be too fragile to survive a single Japanese earthquake, in contrast the Buddhist pagoda at Horyu-ji, Nara, which is the oldest wooden building in the world, was evolved to remain stable in the harsher environmental conditions of an earthquake zone.


The Horyu-ji is 34.5m tall, 4 m taller than Kings College Chapel

The ancient Heian culture that made Horyu-ji constructed their pagodas like Christmas Trees.  The trunk of the buildings are lifted above the ground and the surrounding rooms are attached to the central pole with flexible pegs.  When an earthquake strikes the trunk of the building is isolated from the full impact of the movement of the ground and the attached rooms on the outside of the central mast go up and down a bit like the waving branches of a tree.  This pagoda, which is is higher than Kings College Chapel and nearly twice as old, demonstrates another paradigm of delicacy and stability that was evolved to fit into a different cultural and environmental narrative.

Pagoda at Horyu-ji Temple



Both Kings College and Horyu-ji are huge ancient objects.  By and large technological evolution, as we know it today, is a process of continuous refinement and the machines we make have a tendency to become more efficient, smaller and often so delicate that they can only exist in protected artificial environments.  This evolutionary transition is evident in the evolution of one of our oldest inventions; timepieces.  Amongst the most ancient surviving timepieces are massive astrological calenders like the circle of stones at Stonehenge that measured the passing of the solstices.

3D rendering of Stonehenge by Joseph Lertola
Ancient Bronze age cultures also used water clocks for measuring shorter units of time, the simplest were leaking bowls called by the Greeks clepsydra (κλεψύδρα, "water thieves").  The simplest clepsydra were bowls which had a single small hole cut in their base.  The Romans and Greeks used leaking bowls like these for limiting the length of speeches in their Senates or measuring how much time clients had bought at a brothel.

A Persian Clepsydra (Wikicommons)
There are stories of ancient water clocks that were elaborate Heath Robertson contraptions, amongst the most amusing was an alarm clock used by Plato (428 - 347 BC) to wake his students.  Plato's alarm clock was an empty columnar vessel inside which was placed a wooden cradle containing lead balls, before they went to sleep the students turned on a tap that let water flow into the vessel at a constant rate.  As the hours passed the balls were lifted by steadily rising water to the top of the column where after the allotted time they spilled over the edge of the vessel and fell with an enormous clang on to copper platter.

About a hundred years later, in 250 BC, a Greek called Ctesibius of Alexandria invented an elaborate water clock with cogs that were driven by a siphon escapement.  This clock may have been the first 24 hour clock with a dial and pointer. 


 



For the next 1500 years Ctesibius' clepsydra remained the most accurate way to measure time, his invention spread to China where Zong's water clock was built in 1088.  Zong's water clock was a 33 foot tower with escapements that wrung a bell every quarter-hour.

Su Zongs water clock 1088 was about 33 feet high
In Europe water clocks gradually were gradually replaced with public church tower clocks that were powered with weights. The Salisbury Cathedral clock of 1386 was advanced for its era, it struck a bell on the hour but had no clock face. 

The Salisbury Clock 1386
But water clocks were still more accurate and in use in 1600 when Galileo was using them for his experiments, as an old man Galileo suggested a swinging weight would make a more accurate time regulator than water (1642).   Galileo's idea was developed after his death by Christiaan Huygens who in  1656 made the worlds first pendulum clock.  


Huygens pendulum clock 1656
 
The invention of pendulums was followed by a period of rapidly improving efficiency, refinement and miniaturisation. One of the greatest geniuses of clock making, John Harrison (1693 - 1776), spent most of his early life trying to make sea clocks.

Harrison's first sea clock
As time went by he realised that small watches were often more accurate than his larger clocks and the second half of his life was spent was inventing new finer escapement mechanisms for pocket sized chronometers, like this elaborate and beautiful. grasshopper escapement.  Such miniaturisation delicacy had to be housed in protective casings

his last sea watch was accurate to within a third of a second a day and was not affected by the motion of waves.

Harrison's Chronometer H5, Science Museum, London

Harrison's fragile mechanisms are not as delicate or accurate as atomic clocks which measure time inside a microwave-filled cavity that first cools the atoms to near absolute zero temperature by slowing them with lasers.  FOCS 1, a continuous cold caesium fountain atomic clock in Switzerland, started operating in 2004 at an uncertainty of one second in 30 million years.   We might refer to the stable zone inside FOCS 1 as a habitable zone for atomic timepieces.




The products of  Darwinian evolution also evolve to fit within habitable zones.  All of life as we know it lives in a zone around the sun that is neither too hot or too cold for the delicate structures of life, it is often laughingly called the Goldilocks Zone.  Darwinian Evolutionists call  zones in which species live niches.

The Goldilocks Zone http://planetary-science.org
Sometimes technological evolution creates Goldilocks Zones so that its machines can be designed to run efficiently and super-smoothly, human transport provides just such an example of  co-evolution between an object undergoing refinement and a Goldlocks zone.

“‘The Machine,’ A.D. 1640–1750.” From Sir Walter Gilbey’s Early Carriages and Roads


When we look back at the stage coach of the 17th century we find that a 65 mile journey from London to Cambridge was an arduous two day bone-shaking trauma along the rutted tracks of drovers lanes, by the 1830s, through the miracle of human ingenuity, the tracks were improved and with some modest improvements in the technology of the carriages they were making the same journey in more comfort in one day .

 
Over the next two hundred years our roads have developed into smoothed tarmacked runways that provide a Goldilocks Zone along which the delicate machinery of modern cars can glide at constant speeds of 80 mph, 16 times faster than the 17th century horse drawn coaches and in a lot more comfort.  Inter-locking co-evolution between protective environments and the delicate machinery of life is a common theme in Darwinian evolution.  In our daily lives we are familiar that our body temperature is constant, we also know that when our temperature rises by a degree or two we begin feel ill, if it rises by 5 degrees the machinery of life breaks down and we die.  This is because our metabolism has evolved to run smoothly within in a narrow and stable sweet zone.  Asking our metabolism to run outside the narrow parameters of the sweet zone (which are between 96.5 - 98 c) is a bit like trying to drive  a sports car  across a waterlogged field or an atomic clock at room temperatures.

When we look at the evolving technological achievements of our species, it looks as if our unique ability to apply science and reason surpasses the abilities of Darwinian evolution.  It has taken nature 3.5 billion years to produce flying birds, the mammalian eye and brains.  In stark contrast it has taken a mere 5,000 years ago for humans to go from inventing the cart wheel in Sumeria to creating civilisations that have learnt to build Gothic cathedrals, aeroplanes, cameras and computers.

Cart wheels were invented about 5000 years ago

It is an astonishing fact that our technological evolution has happened at a speed five hundred thousand times faster than Nature. Anyone can see how our buildings are higher and have better air-conditioning than the biggest termite mounds; our aeroplanes and space ships fly faster, higher and further than any bird; our cameras see wider spectrums of light than any eye and our computers solve maths equations at speeds far faster than the brains of our Nobel prize winners.  We can even fly to the moon.  History seems to demonstrate that we humans are far better at evolving machines that will overcome physical challenges than Darwinian natural selection.  Human reason is clever, Nature is dumb, Nature sucks!

As technological evolution gathers pace so does our understanding of how the natural world does things. New cognitive sciences lets us take a cold rational look into our own brains and see how consciousness and intelligences are tied to the purely physical activities of brain structures; glial cells, nerve cells, hormone releasing glands, synapses, dendrites, myolin sheaths and neurotransmitters.  Scientist who work in this field begin to view the brain as a physical "machine" that perhaps contains a mysterious quality that we call spirit or conciousness.  Inevitably they ask themselves "if we are better than nature at making machines then surely we can simulate neural networks with our computers, and eventually we will re-create intelligence?".   Hand in hand with our desire to know about how nature works comes the hubristic niggling belief that we are nearing God's ability to create machines with spirit.


Pygmalion & Galatea by Lasarasu


These fantasies are not new, our ancient myths speak of our making creations like Galatea and Frankenstein that come to life, these fantasies continue in popular culture in TV series like "Humans" that feature androids that seek to acquire souls like those given to us by Nature. It was almost inevitable that the development of computers was accompanied by the genesis of a challenge to test machines for (intelligent) thought.  In 1950, over 65 years ago, Alan Turing, who is most famous for his pioneering work with designing and developing code breaking computers at Bletchley Park during World War II, set the Turing test.



Alan Turing

The Turing test is supposed to test whether machines can exhibit intelligent behaviour that is indistinguishable from that of a human.  Turing supposed that when a human is unable to distinguish between answers given by a machine and answers given by a human, then the machine has become intelligent.


The Turing Test (Wikipedia)


Turing's test was conceived during period when psychology was dominated by various narrow-minded  schools of "Behaviourism".  Behaviourists believed that all science must be testable, otherwise it was not science, they were particularly impressed by Pavlov's famous demonstration that dogs could be trained to salivate to the sound of a bell.  Behaviourists aggressively rejected the intervention of nebulous unmeasurable influences into their studies and models of the mind.  During Turing's day the Behaviourists sidelined discussions on consciousness by introducing a theory of "epi-phenomenology".  Epiphenomenology explained away our consciousness and feelings as being a mysterious and irrelevant by-product of the mechanical processes of the brain that had no useful purpose.  Using this belief behaviourists effectively made  the study of consciousness, feelings and even emotions were taboo subjects within academic circles. Turing's test seems to fall into the trap of assuming that consciousness was either irrelevant to thought or would spontaneously ignite when the mechanics of thought passed a certain threshold or were replicated in a correct manner.  His test is almost a variant of the commonly quoted aphorism that if it looks like a duck, walks like a duck and quacks like a duck then it probably is a duck?  If you cut the duck in half and find out its brain is made of wire and transistors you can still classify it as a duck because the wires inside the duck replicate the mechanics of the mind, so for the Behaviourists of Turings day the fact that the duck's brain was not made of flesh and bones did not preclude the duck from having consciousness and intelligence.

This attitude still prevails in the style of our reporting on advances in Artificial Intelligences, usually comparing them with feats of the human mind..  In 1997 a computer called Big Blue beat Gary Kasparov at chess, this year AI passed a new milestone when a machine called Libratus beat four of the world’s best poker players in a gruelling 20-day tournament. (Poker is harder than chess because each player players don’t get to see each other’s hands and have to correctly interpret misleading information in order to win).  At the populist end of are our dumb cars and phones that have "smart" technology to talk with us and answer questions,  robots that have been developed as companions for the elderly and a virtual assistant called Alexa that has received 250,000 marriage proposals.  Recent AI  machines often do not come out of the box fully programmed, they need to be taught and learn their jobs.  For many people computers are already passing the Turing test and are intelligent, but for others virtual intelligences are examples of the computer industries becoming better and better at creating fraudulent illusions of consciousness in machines.

There is a well used thought experiment called "the Chinese Room Argument"

You are asked to imagine yourself inside a closed room with an instruction book and a post box through which you receive messages from a Chinese person on the outside.  When you get the messages you look in the instruction book and match the squiggles against the reference book and follow instructions, you end up posting some squiggles back to the outside world.  The Chinese person outside the room thinks you understand how to read and write Chinese, inside the room you have no idea what the messages were about or how you replied.

The trick behind  Artificial Intelligence (AI) is exposed in Jeff Hawkins' book On Intelligence (2004) where he tells us about his thought experiment:   "....a typical neurone can reset itself in about 5 ms, a modern (2004) computer do one billion operations in a second"...... "A human can perform a significant task in much less than a second.  For example, I could show you a photograph of a cat and ask you to determine if there is a cat in the image".......(Not a bear?)......"This task is difficult or impossible for a computer to perform today (2004), yet a human can do it in reliably in half a second or lessBut neurones are slow, so in that half second, the information entering your brain can only traverse a chain of one hundred neurones long.  That is, the brain "Computes " solutions to problems like this in one hundred steps or fewer, regardless of how many total neurones might be involved.......a digital computer attempting to solve the same problem would take billions of steps.  One hundred computer instructions are barely enough to move a single character on the computers display".  Big Blue, Libratus and Alexa achieve "intelligence" by following billions of instructions that would take a human brain years to compute. AI, as we know it, has been achieved through making a Chinese room with hugely superior computing speeds combined attached to huge data storage, but the engineers who designed the programs had no intention to include emotions or consciousness into the mechanics of how their machines work.  The machines they have made beat our minds on many tasks whilst on others they struggles to do relatively simple things that the human brain controls with ease.

When we look at intelligence we meet a paradox, I call it the Intelligence Paradox:  This is a hi tech Camera designed with the power of reason.



Like your I-phone the camera contains many components; data storage, zoom lens controls, flash, viewing screen, apertures, batteries and WiFi.  As mentioned earlier some niches are very specific; such as to be used inside I-phones.

Contrast this with an eye which is made of millions of cells that collect billions of particles of information about light that is sent into the black depths of our heads where our brains re-assembled the data through trillions of neurones with zillions of dendrites and synapses to recreate a virtual world of light and moving images and consciousness.



If the eye was constructed by the dumb forces of Darwinian evolution, why did we need intelligence and reason to make the less complex camera? Before Darwin's time we answered this paradox by believing in a higher divine intelligence that used superior powers of reason to create the world.
William Blake "Ancient of Days"


Today we have lost that defence and face a challenge to our notions of what intelligence and creativity are.  About four decades ago, after the Behaviourist's taboo against scientists studying emotions and consciousness had subsided, attention became focused on the role of emotion in decision making.  It is now understood that "somatic tagging" of our emotional responses to objects and situations provide us with swift subliminal guidance about what to do next, and these responses, along with reflexes, keep us safe from danger.  Reason and deliberate analysis give us forethought, but in real life situations where split second decisions have to be made on the fly these sorts of intelligences are too slow and indecisive when measured against the speed and efficiency of emotion led decision making.  Reason evolved to provide an extra layer of opportunity to weigh and correct the emotional guidances when or after they go wrong.  Reason gave our species forethought, design abilities for toolmaking and other huge competitive advantages when hunting other animals, but as pointed out in Antonio's Damasio's seminal book, Descarte's Error and by Joseph Le Doux in his work on fear responses and emotional trauma, reason is only one part of a suite of intelligences that are available and useful to us for our survival. 

Could Darwinian forces be called intelligent? Typical of this sort of reasoning is Guy Claxton's modern approach in his book  Hair Brain Tortoise Mind (1997) where he describes intelligence thus: "At its most basic, intelligence is what enables an organism to pursue its goals and interests as successfully as possible in the whole intricate predicament in which it finds itself".  Twenty years later, in his new book (2016) Claxton defines intelligence even more succinctly as the "knowledge to do "what is the best thing to do next?".  Claxton's descriptions embeds intelligence with evolutionary creative forces and leads us to expect that intelligence is a natural outcome of Darwinian evolution, in which case we must expect to find intelligence embedded in early products of Darwinian evolution too.  Single celled life forms like bacteria and even viruses, some of which have as few as 7 genes, should be intelligent too?  In the last decade a tidal wave of evidence has flooded in to support this prediction.

In this film you will see how single celled slime moulds learn to navigate through a maze to food.

 
This is great video to watch!

In another study the microbes were set up to solve Soduku puzzles (link).

And just today there were newspaper reports about the cognitive powers of bumble bees which are much better and individual that we ever suspected.  https://www.newscientist.com/article/2122383-bees-learn-to-play-golf-and-show-off-how-clever-they-really-are/

When Darwin coined the phrase "Survival of the Fittest" he set us off on a train of thought that was a bit misleading because the phrase infers constant competition between species (competition between plants and animals that do not share the same genetic material).  But how about when the choice is between fittest individual cell and the fittest symbiotic relationships, such as when free swimming microbes began to combine into multicellular clumps that work together? There are single celled organisms that live on this dividing line of switching between being free swimming single cells and becoming multi-cellular clusters that work together, amongst those studied are the water-borne Choanoflagellates that feed on bacteria that are being studied by Prof Nicole King of Berkley University.  Sometimes, when the "choanos" split to reproduce, they fail to separate and instead stick together in rings that become spheres.


The interesting discovery is that the Choanos only become multi-cellular in the presence of certain food resources (bacteria).  These simple life forms become co-operative with their cloned sisters when their food source are present in large enough numbers.  At some point in our history survival of the fittest single cell became survival of the fittest community and after this transition our rivers, lakes, seas and oceans began to team with simple multicellular  plant and animal life.  At the heart of this development was embedded inter-cellular knowledge and behaviour towards each other, both friendly and hostile.  It would have been been bit heavy for Darwin to have said "survival of the fittest individual and/or communities", but it would have been less misleading.

Communities, whether they be socially connected groups of people or primitive collections of cells like the choanates, work most efficiently when the component parts work in harmony.  Such harmony within multicellular communities will be enhanced by good inter-cellular communication, especially intelligent communication.  Evolution of "higher" life forms became the war between cellular communities. From such simple observations we should predict that Darwinian evolution would preserve this principle of harmonious communication that was already present at the birth of multicellular life, and these inter-cellular abilities would have been developed and maintained within the bodies of more complex animals and plants; when we look at our bodies we discover that cellular communication and intelligence are built into the brickwork.

There is a new word for this sort of intelligent decision making, embedded cognition, and we know it is happening on a grand scale, most notably in the " enteric system" of our guts which has very a large concentration of brain cells that produce more serotonin than our brains and is sometimes been called "The Second Brain".  

The Second Brain

It is now thought that every organ; the heart, the liver even the skin are in constant two way intelligent communication with the whole body as well as with the brain which co-ordinates and priorities the use of resources.  We are discovering that on a micro-cellular level our bodies are riddled with intelligent intercellular communication, to pick just one example from research this year; in the walls of our capillaries are 10 - 50 trillion cells that do not just carry blood, they work in teams and use the blood vessels to send signals stimulating, regulating, maintaining and inhibiting very unique stem cells for each organ of our bodies. 

Another surprise is that intelligent inter-cellular communication is not confined to cells that share the same DNA, it is also happening across species barriers; such as between the cells of our bodies and the microbiome in our guts.  Our bodies contain about two pints of microbial life, which sounds like a small proportion, but their smallness makes them outnumber our bodies own cells, they also contain 300 times more DNA than we have received genetically from our parents.

A lot of this behaviour only became better understood from studies with germ free mice that are raised and live in sterile conditions (Gnotobiosis).

Gnotobiotic Lab for keeping Germ Free Mice in sterile conditions
The mice in gnotobiotic labs have bodies that have been cleansed of all bacteria and live in sterile conditions.  These unfortunate animals grow up to
have altered patterns of brain development and behaviour and almost no resistance to disease, however when they are exposed to a mixture of bacteria, the changes reverted back to normal. In 2013, a team of researchers discovered that if a sample of the gut microbiota of an obese human were put into a germ-free mouse—with no changes to the mouse’s diet—the mouse would gain weight. If the microbiota sample was instead from a lean human, the weight gain did not occur.  Following the experiments with obesity, gut microbiota have also been linked to autism, Parkison's disease and cancer, they are also known to influence our mood swings and the way we make decisions and neutralise poisons in our foods.

This has led to a new idea that our bodies are not really single entities with a single DNA heritage, we are "Holobionts"; symbiotic communities which share multiple lines of DNA heritages from which we acquire services which are exchanged, modified and sometimes lost during our lifetimes. In some holobionts the microbiota outweigh the cells of the host animal, such is the case with Paracatenula, a tiny flat worms that live in the sediments of warm oceans. These holobionts hold their bacterial symbionts packed into compartments (trophosomes) that fills 90% of the worm. 

Paracatenula - bacterial symbionts fill 90% of its body


If you cut a portion of the tail its off it will regenerate a new head from a mixture of stem cells and bacteria, but if you cut the head alone (without the bacteria) the animal cannot regenerate and dies.  

At  the heart of the life as a holobiont is the need for the symbiotic partners to communicate and co-operate.  Even though the bacteria in your stomach do not share your DNA they do share a common interest in the maintenance of their stable sweet zone environment and your well-being, and we share an interest which is only maintained through looking after your well-being. This relationship is reciprocated and we nourish our microbiota with a stable environment and probiotics. This interdependence has become a central reason for evolving intelligent dialogue between us and our helpful companions.

The lining of the gut is very thin, only one cell thick across which it wpuld be easy for toxins and hostile viruses and bacteria to cross into your blood stream, what stops this happening is a thin layer of mucus that is teaming with symbionts. Sometimes it is likened to a garden, however perhaps ti would be more accurate to think of it as a coral reef or Tropical rain forest since it is more like an ecosystem that looks after itself without the need for weeding.  When the mix of nutrients change the mix of microbiome change too.









When we look at the beautiful structure of a blade of grass, such as this strand of Coxfoot grass that grows a metre tall is less than half a centimetre thick at its base, it looks like La Sainte Chapelle, an optimised Goldilocks balance and physical marvel...and indeed it is




but the grass is only a stem whilst it is making its seed, after it seeds are spread it decays back into the soil.  In the cold winter months the seeds sleep in the soil waiting to erupt and grow in the spring sunshine and be a meter tall again.  Our bodies are like this, we are never really still, even when asleep we are dreaming, breathing and ageing.  Living things are events, which is different from La Chapelle which is a man made thing that can only survive by being absolutely still in a non earthquake zone.  La Sainte-Chapelle is unchanged from the day is was built 800 years ago.  The Stones in the walls of do not talk with each other, that is the point, they are held together by the laws of physics alone and do not have the need to keep the event of life on the road.

La Chapelle made of inert stone, looking the same as it did 800 years ago


Likewise the transistors and wires and silicon chips in my computer do not grow old, they just gets battered and worn out.  My computer is a man made thing, it sometimes behaves like a living event, but inside there is no need for intelligent conversations between the wires and chips, there is no need for the computer to monitor the sense of well being of its components, and there is no need for the computer to develop consciousness to keep it safe in a world of constant change, we do these things for the machine we made.  

Darwinian evolution made intelligence, and consciousness for that matter, because intelligence is necessary to keep the event of life on the road.  Life could never blossom without Natures invention of intelligence.  And Consciousness, that too is another aspect of intelligence, another invention of the deaf, dumb and blind but perhaps intelligent watchmaker.

In the paradigm of our minds, in our paradigms of civilisation, empathy, war and sociability runs the theme tunes of the song of Darwinian evolution.  In the bugs of our stomachs, their intelligence mixed with the event of our mortal bodies, are the origins of our souls.  In all our creations; in our Art, La Sainte-Chapell and in our I Phones all made of wire coils and batteries we find metaphors that speak to us about Darwin but it is in the stem of a single thread of grass that we find the real deal, in the intelligence of Grass we will always find ourselves...........

When we look around us we see a world that is filled with examples of human evolved know-how, just look at how precisely the component parts of your mobile phone have been optimised and assembled to fit in your handbag or trouser pocket; for each component the designers have made traded offs; battery life against weight and size; strength against size and usability.

Darwinian co-evolution does not only happen within the confines of our bodies, we all know that plants would die without the bees that pollinate them, and the bees would die without the plants that feed them nectar.  Co-evolution also occurs at microscopic ecological levels, the building blocks of our bodies are of a complex type of cell called Eukaryotes, inside each eukaryote cell are structures called organelles such as mitochondria that have their own DNA and divide like bacteria.  It is believed that  two billion years ago the ancestors of mitochondria were single free living prokaryotic cells that somehow made their homes inside eukaryotic cells where they were welcomed as power generators, as the relationship developed the mitochondria amalgamated themselves into becoming just one more functioning part of their hosts.


Mitochondria have their own DNA and divide like Bacteria (biomedicine blog)





In technological evolution we get similar examples of symbiotic partnerships between machines, perhaps we can see it in the development of cameras inside I phones.
