Consilience

John Brooker of Long Wittenham, born circa 1720 in Berkshire area? My 6 x great granddaddy. Gemini AI visualised this image based on my own features and on his recorded life.

Why so much hyper-focus on my Y chromosome just recently?  I guess because I have made a few breakthroughs on other lines of the family tree. I had a long conversation with AI about my paternal line and we came to agreement that I had made an error. That had to be put right. After removing those errors, this is where I got back to on my direct paternal line (aka surname line):

  1. My 6x great grandfather was named John Brooker.
  2. My 6x great grandmother was named Mary Gardiner. She was born in 1717 at Hagbourne, Berkshire.
  3. This couple married 1st November 1746 at Oxford College, Oxfordshire. They were both described as residing at Long Wittenham, Berkshire. I have discovered that the reason that they were married at Oxford College was that their parish had been allocated to a vicar living in Oxford College. It was cheaper for them to be married at Oxford, than to call the vicar back to their parish.
  4. Following marriage, John and Mary Brooker proceeded to have at least six children born at Long Wittenham - Mary, Anne, John, Edward, Martha, and a Sarah Brooker. John was a copyhold tenant of St John's College, Oxford, who were one of the two main land holders at Long Wittenham. As a copyholder, John would have cultivated a number of strips in the open-field systems still being used at Long Wittenham. He wasn't a pauper, but neither was he likely to be particularly wealthy.
  5. Before 1746, I have baptism and ancestry for his wife Mary nee Gardiner, but for John, it's the Great Genealogical Dead End.

What were these errors that I deleted for 6 x great grandad John?  I had found numerous John Brookers baptised circa 1720 in the local area. After much deliberation, I settled for the closest village to Long Wittenham, the parish from which his bride had also moved from, I chose a John Brooker baptised at East Hagbourne. But in my heart I knew that there were issues with this choice. For one thing, a lack of correlation in the names of children. Then I became convinced that the John Brooker of Hagbourne, had lived a separate existence from the John Brooker of Long Wittenham. Genealogical crisis!

I immediately recovered from the shock, and started anew with fresh 2026 research. After all, I started out on this quest in 1989, and things have moved on a tad since then. Not only with digitalised, indexed, and online genealogy, but also with genetic genealogy. This is where I shall take this discussion next.

Around 12 years ago, I tested my y-DNA - the DNA that is contained in my Y Chromosome. This can only be passed from biological father to son. Trace it back, and it follows the direct paternal line, all the way back to Y-DNA Adam in Africa. You can use its variants (aka mutations) to tell a story of that one narrow line of descent, way back into prehistory. It does not ALWAYS follow the surname line perfectly, because of illegitimacy as it was previously known, adoption, affairs, and more. People sometimes change name to escape from their past. In the long term, the y-DNA surpasses the origination and adoption of surnames as they occurred during the Medieval.

I've discussed to death the route this genetic evidence tells me that my paternal ancestors must have taken in the past, and will continue to do so:

  1. 28,000 years ago Ice Age hunters of ibex and mouflon in the Zagros mountains of South-West Asia.
  2. 11,000  years ago, hunter-foragers still in the Zagros, or in the Caucasus mountains, who were selectively hunting wild herds, and milling gathered wild seeds in ways that would eventually evolve into the earliest agriculture.
  3. 8,000 years ago my paternal ancestors were aceramic neolithic farmers, herding goats, and sheep. Keeping pigs. Growing emmer and einkorn wheat, barley and more. They may have remained in the area of the Zagros, on its foothills where they founded the ancestry of the Hurrians and Kassites. Or perhaps they had moved immediately southwest, onto the floodplains of early Sumer (Iraq) where they would give birth to a great civilisation?
  4. 4,000 years ago. They would have been in contact with great cities in Mesopotamia, Assyria, Babylonia, the Indus Valley, the Levant.
  5. 3,000 years ago. Perhaps swept westwards to the Levant by the fall of the Mitanni, and the dispersals of the Hurrians.
  6. 600 years ago. Maybe a Genoese or Venetian galley docked at Beirut, Acre, Jaffa or Tripoli and took on my paternal ancestor as crew. My yDNA finally leaves Asia, and heads for Europe.
  7. 600 years ago. A galley docks at Southampton in England, where Genoese and Venetian merchants have a permanent presence, interested in English wool. My last Asian ancestor leaves a son in England.
  8. 400 years ago. Our line has taken the surname Brooker, or is it Chandler? Perhaps a child is born outside of wedlock. He takes his mother's surname. The yDNA is consequently divided among two families in the area of Basingstoke, Kingsclere, Sherfield Upon Loddon, and Newbury across the Hampshire/Berkshire border. Chandlers and Brookers.
  9. 280 years ago. My 6x great grandfather, John Brooker lives in Long Wittenham, Berkshire.

The above is a hypothesis based on those variants on my Y DNA, along with the fact that it survives only in Europe, among two small families who were living only 32 miles apart during the 18th century. Thomas Chandler of Basingstoke, and John Brooker of Long Wittenham. Comparing the DNA, there is a 78% probability that the two families shared the same great grandfather line until circa 1600. Our type of DNA (L-FGC51036) is not found anywhere else in Europe. Our closest Y-DNA cousins are from Iran, and Saudi Arabia. Further back in the variants we have Y-Cousins from Iraq, Lebanon, Pakistan, India, in the Druze ethnicity, in the Parsi ethnicity.

Getting back to the documented record. Our John Brooker. Where did he come from? The DNA does keep pointing south in Berkshire, and to the Hampshire border. A meeting with the Chandlers of Basingstoke. I investigate all of the 'John Brookers' baptised circa 1720 to the south. There can't be many can there? Wrong. I found at least 9 candidates in that part of Berkshire. I have eliminated several from the search, but Berkshire genealogical records are not the best online! I'm usually limited to indexes of transcripts. Transcripts are often wrong. More dead ends.

So I turned to trying to trace back from the Chandlers of Basingstoke hoping that might put me on to the right track for the early Brooker family. I keep hitting more dead ends.

However, here is the thing. Parishes like Chieveley, Newbury, Kingcslere, Sherbourne St John, Sherfield Upon Loddon. I often see entries for baptisms, marriages, and burials for both 'Chandler' and 'Brooker' families. In same villages, registers, sometimes even same pages!

I can smell consilience. Documented trail, and Genetic trail. So close.

The Ultimate Ancestor.


When I envisaged this post last night, I was simply going to make it an easy, simple little table of the L haplogroup variants on my Y Chromosome. I had a few problems with that, and therefore consulted for a while with Google Gemini AI. Before I knew it, my post grew and grew. I know that I have a particular kind of mind. One that hyper-focuses, sees patterns in data, and buries itself into whatever science, history, or nature that currently catches my attention. As this blog is intended only for me to enjoy making my observations, I shouldn't be apologizing.

Gemini helped me a little with organising the dating, and contexts of the yDNA. When I was happy with it, I then felt that the beginning of the story was far older than yDNA Adam, and therefore I asked it to add some information on earlier human evolution. But then that wasn't enough, because humans are only the recent end of just one lineage of life, so I asked it to add the story of Life on Earth. But then I knew that wasn't enough. You see, we are star dust. We see ourselves as selves. As individuals that matter the most. We make our own ego. Yet all life is entwined, and interdependent. Every several years, every cell in our body is replaced. Even as an individual I am no more than a chain of events, a process rather than a thing. A small percentage of my bodyweight isn't even the same species - it belongs to countless micro-organisms of a biome. We are also a lichen,

We interbeing not only with life, but with the universe. The matter in the fingers that punch this keyboard have been a part of other lifeforms before me. My existence has consequence for everything. Enough of the profound thoughts, let me get this list of my process down.

​The Dawn of the Y Chromosome

  • ​Age: c. 180 Million Years Ago

The Origins of Henry Shawers - revealed!

Above image of my ancestor Johannes Heinrich Sherz aka Henry Shawers, visualised by Google Gemini AI

Forty years ago I bought a marriage certificate for my great great grandparents, Henry Brooker and Elizabeth Rosina Shawers. There were no 'online' genealogical services then, and in order to find this certificate, I had to personally reference the paper indexes at the registry office in London, and order the paper certificate there. I thought that 'Shawers' was an unusual name, and suspected Huguenot. As bride, she declared on the certificate that her father was a narrow weaver named Henry Shawers. I later found out that a narrow weaver, was a lace weaver, who specialised in making fine lace e.g. for collars and sleeves. Over the forty years, I continued to make occasional attempts to learn more about Henry:

https://paulbrooker.posthaven.com/henry-shawers-a-weaver-in-the-tree

I discovered that he was actually a Swiss-born immigrant, and that he was illiterate, only about 163 cm tall, slight, fair, with blue-grey eyes. But I never could find anything about his Swiss roots. Not his first language, canton, etc. All that I knew was that on record the original names of himself and his father (John Shawers, coppersmith) had been anglicised.  To help my search, I built a life time-line for him here:

https://paulbrooker.posthaven.com/henry-shawers-timeline-of-an-ancestor

I had an immigration record of a Henry Shawers from the 11th August 1852, as a passenger on the Lord Warden, that disembarked at Folkestone docks. I found him in prison records and on a census. But no Swiss roots.

Well, AI has helped me to change that situation!

I am now proud to announce that our ancestor Henry Shawers, was born on 26th July 1827 at Köniz, Bern, Switzerland as Johannes Heinrich Sherz, son of Johannes Sherz and his wife nee Rosina Zürcher. Their first language was most probably Bernese Deutsch, and Canton was Bern.

Gemini AI has proposed further ancestry for my Swiss 4th great grandparents, but on that, I am hesitant to claim without discovering more evidence for myself. Gemini has portrayed social decline in recent centuries for the Swiss family in the countryside close to Bern. Napoleonic wars, Independence, civil strife between political fractions. This followed by the price competition of goods being factory manufactured in British cities, and finally, by a potato blight and the 'Hungry Forties'. This was the background to Johannes aka 'Henry' applying for a permit to emigrate, found in the Bernese District Records (Amtsbezirk Bern) from late 1851:

​Status: Heinrich Scherz, born 1827, weaver. ​Action: Granted a Wegzugsurkunde (Departure Deed). ​Context: The record implies he was traveling "nach England." This perfectly aligns with your August 1852 arrival on the Lord Warden. He likely spent the winter of 1851/52 working his way through France (Boulogne) before crossing to Folkestone.

Gemini also suggests why records later show him moving between London and Brighton. He was almost certainly tramping for work. I asked the AI if it would generate a portrait of my ancestor, and gave it an age, social conditions that he was living through, and a prison description. Gemini gave my the image above.

Age of the Degeneracy - reconstructing the Late Mesolithic of Britain

Image Source - my own, taken today, of a flint blade from an old finds box. Thetford Forest. It would have been recorded as a snapped blade, possibly transitional Mesolithic-Neolithic. Now in the 21st Century I understand that this blade was strictly, Mesolithic. I no longer believe there was transition.

I've written a novel. The story provided me with an escape from unbearable life. The tale has two primary settings, both circa 6,000 years ago.  One in what is now South Iraq on the edge of the marshes where civilisation starts to take shape, and the other in South East Britain, as Mesolithic hunter-gatherers meet Neolithic farmers. It is a little play on parts of the Genesis story.

I was cut off from all Nature. I am only just now starting to reconnect. It will be a very long healing experience if I decide to maintain it. Because I'm running short of hope. I had very little access to data. I had to scrap around in order to attempt any understanding of how the Mesolithic British may have experienced life, and was left with little more than contemplation. This is how I reconstructed a fictional South-eastern British environment 6,000 years ago:

Natural Britain during the Early Holocene

Birch scrub advanced first. Followed by pine, yew, and other evergreens.  This is the Age of Star Carr. The tundra grasslands receded with this rapid advance. Temperatures increased annually. Waters began to rise.

The birch grew taller. Alder joined them. Willow and holly. Followed by oak. Lime and hazel arrived on the British peninsular of North West Europe. Wych elm, hawthorn, blackthorn then ash. In South Eastern Britain, it was the lime which dominated as the most common tree.

Tree biodiversity was actually quite limited in Late Mesolithic Britain. Because the North Sea (Doggerland), and the English Channel, flooded with thawed out glacial waters to make Britain an island, before more species could shift across any land-bridge.

Later Mesolithic SE Britain.  Wild-woods or temperate-forests?

I suspect that the term temperate rainforest should be reserved for the wetter parts of the British Isles. Particularly for the west. Across the drier south-east of Britain, I propose that it would be better to describe it as wildwood.  Even here I suspect that the ecology was incredibly rich, with mosses, lichen and fungi.  Some areas of the wildwoods were kept quite open by the actions of large wild bovines that generated their own woodland pastures. Others were more dense.

The British canopy was not continuous. Breaking it were small glades, and some larger plains. These were kept open by browsing and grazing herbivores that herded in the open - aurochs, red deer, bison, roe deer. A distinct ecology existed on these small scrubs and prairies. 

Equally there were lowland marshes and fens of reed bed with water-logged islands of alder carr. Often, belts of these ran up the riparian terraces of river valleys to provide rich habitats for birds, beavers, and pig. The rivers were clean, and ran naturally within their floodplains except for the works of beavers. Upper stretches of chalk streams would have been choked by Summer watercress. Alder and willow trees dominated the riparian belts. Banks were not cut, and rivers wider, bordered by the roots of alder, or by gravel shores. They often flowed around riverine islets and over gravel banks. Water channels changed their many courses through the marshes of deltas.

Bird-life was devoid of some species that have adapted to and follow human agriculture, but could have included some surprise species no longer in the British Isles such as black woodpecker, black stork, and European eagle owl. These in addition to species such as titmice, woodcock, wood pigeon, tawny owl, bustards, and cranes. Goshawks would have been a widespread raptor across the forests, and white tailed eagles not an uncommon site.

Mammalian predators included wolf, brown bear, lynx, fox, badgers and martens

Image Source - taken on the phone today.

I've demonstrated in recent posts that the Mesolithic hunter-foragers in Britain, most likely descended either from the Ice Age Epigravettians of Italy and South East Europe. They or / and perhaps recent arrivals from South West Asia, who had crossed a dry Aegean. A recent study of ancient genomes supported the former population.

We know that they appear from genetics to be dark skinned and possibly with light coloured eyes.  That is just a fine detail. To those people that make a deal out of it, I ask why? And I love the reconstructions of western hunter-gatherers by Tom Björklund.

What was the environment in South East Britain, 6,500 years ago? How had they adapted to the changed environment?  Their ancestors had survived the Ice age mammoth steppe. They had survived so long on the tundra.  What challenges had the Holocene's new forests thrown at them?   Their ungulate prey species had dispersed from herds in the open, and into the woods. There, they were more difficult to locate, and could quickly disappear into cover. They had less need to form large herds.  Temperate forests release a lot of their calories only during the autumn. To survive, Mesolithic hunter-foragers needed to be exceptionally intelligent. They needed to break up into smaller bands, and adapt to a forest way of life

How I portray Late Mesolithic Britons in fiction

The wild-woods may not have always been dense. Yet they would have been difficult for humans to traverse by foot. Deadwood would have laid across everywhere. Its rot fed the ecology. Moss and dead leaf-mould, deep. Some alder rain-forests would have been likely waterlogged and swamped. Walking across these environments uses a lot of calories that are otherwise precious.

It was probably easier to travel by waterway whenever possible. Although upper rivers might be seasonally clogged by growth, and beaver dams a trial. Watercraft include dugouts, but also canoes of bark or animal skin. It would have been the way to travel.

During this travelling, few people would have been encountered. The bands dispersed in order to make best use of resources. Human population was likely very sparse across Britain.

Image Source.  11,000-year-old skull headdress from Star Carr.

Food opportunities were seasonal:

Late Winter / Early Spring. Bands would have radiated out of winter encampments, hunting deer, pig, among other prey species. But these themselves were losing all winter fat. The Mesolithic people may have relied heavily on caches of roasted nuts and other preserves. Or chewed tree resin and inner bark to stave off hunger. Fish were available, through traps, nets, spears. Eel, chub, and pike. This may have been the lazy time, when they sat around hearths, preserving expensive energy.

Late Spring.  Wild greens, pignuts, tubers, flowers, cat-tails, buds, even young tree leaves of elm and hawthorn. Slow game - birds eggs and chicks. Possibly European pond turtles. Roots such as those of cat tail could be dried and ground into flour.

Summer.  I have my fictional hunter-foragers moving to the coast during summer, where they meet up with other bands for sports and social networking. There they could have foraged sea beet, sea lettuce, samphire, buckthorn berry, and shellfish. Mussels, oysters, clams, cockles, razor shells, whelks, crabs.  Perhaps hunted seals on the beaches and sea flats.  Cetaceans would have been vastly more abundant in the seas, and whales would beach, providing opportunities. Sea canoes might have provided the opportunity to fish with nets, or to hunt small cetaceans. Late summer inland, and wild berries - raspberry, mulberry, sloe, brambleberry, elderberry, buckthorn, hawthorn.  Early fungi such as puffballs, parasols, chicken-of-the-woods.

Autumn / Early Winter.  Busy squirrels and martens could be snared.  Game is now at its fattest.  The salmon run on more British rivers than today.  But this would also be a time for foraging nuts and seeds. The hazel-nut may have almost been a staple, at least as a preserve.  It would have been roasted. It can be ground into flour to make bread and biscuits. Acorns were also abundant. They could be rinsed and soaked to remove excessive tannins, then added to flours. Pine nuts if many of their trees remained in South East Britain. Wild grass seeds could be harvested.  Beech probably arrived with the Neolithic. I imagine the small camps being busy at this time of year, processing acorns and nuts to be cached as food reserves. Edible fungi including bollettes, ceps, chanterelles, deceivers, and many more will carpet the wildwoods.

Image Source. Aurochs in a wild wood.

The dark honeybee was most probably abundant in the lime tree forests. I’m sure that their hives in dead trees would have been exploited for honey and wax. The honey could be eaten, or used to make mead - perhaps adding some berries for yeast. Birch and tree sap could also be enjoyed, and fermented to make alcohol. Hallucinogenic mushrooms would have been exploited. The beeswax would also be added to tree resins to make their glues.

Favoured prey species for hunting would have been the red deer, also roe deer, wild boar, aurochs (enormous wild cattle), European bison if they remained, tarpan / wild horse, fox, badger, beaver, etc. Bird species on the menu probably included geese, ducks, cranes, swans, bustards, wood pigeons, turtle doves, woodcock, snipe, etc.  My savages had the domestic dog, but it is a laika-type, that does not bark. It is useful for tracking prey by scent. Dogs also provide companionship and warmth in a den.

The belief system that I designed for my fictional savages was animist. The sense of self, and of afterlife, is projected onto everything natural - prey, trees, tools, the forest, and otherwise. Areas of natural resources became sacred. My fictional savages had female shamans, and were matrilineal. Celebrations and feasts would be frequent. They would engage in sports.  I also suggested some ritual cannibalism, if only to prevent the ghosts of enemies from extracting revenge on the living. I portrayed them as very egalitarian, with little personal property, and no chieftains. But they had different roles for either gender, and the elders were respected.

My fictional savages have a totem-identity, but I'm not sure that would have been the case. Again, my choice was to tie them to local nations set into a larger territory called a wilderness. These nations I divided into smaller more practically sized family bands. None of this is based on any strong anthropological evidence, and was entirely my own creativity.  In reality, bands could have had a wider more homogeneous identity, and ranged wider across the British Isles, free of tribal territorial restrictions. Yet I see this as leading to conflict.

Birth rate in my savages was controlled by extended nursing and delayed weaning in comparison to the Neolithic farmers. This reduced fertility. Otherwise competition would grow for limited natural resources, and local prey extinctions. Conflict between bands would follow as an ultimate population control.

Have I romanticised my Mesolithic Britons? Absolutely I have. I am envious of their freedoms, their relationship with Nature. I see progress as degenerative. 


That is how I creatively wrote the British Late Mesolithic.

Western Hunter-Gatherers - the European Mesolithic

The final in my series exploring the hunter-gatherer cultures of modern humans within Western Eurasia. First I briefly looked at Apidima fossils as evidence that modern traits had been in Europe from an early date. With the Aurignacians, I investigated the earliest known modern human culture in Europe. With the Gravettians, I learned about how hunter-gatherers adapted in the lead up, and into the Last Glacial Maximum How they divided into the Solutrean Culture of Iberia and France in the west; and with the Pavlovian and Epigravettian Cultures of Italy, Czech and the East. With the Magdalenians I discovered how they burst back following Last Glacial Maximum, and through the warmer Bølling–Allerød interstadial.

Above image is my own. Years ago, I recorded several flint microblade waste cores, of which the above wasn't the most regular or impressive. But it's a photo that I could still resource. These artefacts, along with a tranchet axe-head and a few microliths that I recorded, were Mesolithic. I thought that it would be nice if I could bring this series to a close with something, a bit more personal.

Genetics

Let me first sum up the whole Upper Palaeolithic story according to Ancient DNA.

We have established that the Aurignacians had descended from early West Eurasian lineages (in South West  Asia or further north among descendants?) when they split from ANE (Ancient North Eurasian). An early expansion into Western Europe first occurred circa 43,000 years ago, but a volcanic event in Italy may have terminated this occupation, with it resuming afresh circa 37,000 years ago.  They had since admixed with Neanderthals, and on average had 4-5% Neanderthal DNA with long segments. Neanderthals were likely still present in Western Europe, when the Aurignacians arrived there.

Through all of these Upper Palaeolithic cultures, prey species, conditions, and temperatures varied across the entire Eurasian range, with woodlands sometimes forming in Iberia, as opposed the the great Mammoth Steppe further east. Consequently, cultures and perhaps genomes divided into western and eastern blocks over time.

After 33,000 years ago, the Gravettians arrive from the North East, to replace the Aurignacians. Pushed by worsening climatic conditions, they also divided into west and east. Some descendants or relatives of the Aurignacians must have still been surviving, for Genetic studies suggest that during this period of stress, that the original Gravettians were in turn replaced by people who had more Aurignacian-like DNA. The technology and the artefact culture did not evidence this reversal of population.

Last Glacial Maximum passes, and 17,000 years ago, the Magdalenian Culture arises. The population behind this change were not so much the Solutrean of the west, but the people of the Epigravettian of Italy and the East. And they carry Aurignacian DNA. Very late, the Creswellian Culture develops in Britain, along with the Hamburgian around 12,000 to 10,000 years ago.

That brings me up to date with the Western Hunter-Gatherers and the approach of the Holocene.

WHG as a genetic component

So which of these groups did this component descend from?

Chasing this up brings me back to:


In this study, the authors found that WHG ancestry could be located into the Epigravettian genome. That hunter-gatherers had moved up primarily from the eastern and southern refugia to reach places like Britain.

WHG haplogroups so far identified

yDNA are I2a1 (I-M26) and R1b1a (R-V88)
mtDNA are U (mainly U5, U2 and U4)

Were the Earlier Mesolithic people of Britain related to those associated with the Creswellian points? Possibly. Or they could represent a fresh migration most likely not from the recently dominating Magdalenian Culture, but from the descendants of the earlier Epigravettian of SE Europe, possibly with admixture from  fresh populations crossing a dry Aegean from SW Asia:

Wikipedia:

The WHG displayed higher affinity for ancient and modern Middle Eastern populations when compared against earlier Paleolithic Europeans such as Gravettians. The affinity for ancient Middle Eastern populations in Europe increased after the Last Glacial Maximum, correlating with the expansion of WHG (Villabruna or Oberkassel) ancestry. There is also evidence for bi-directional geneflow between WHG and Middle Eastern populations as early as 15,000 years ago.

The WHG of Western Europe is sometimes referred to as the Villabruna or Oberkassel Cluster. They attracted public attention, when analysis of their DNA revealed that they were genetically likely to have had dark hair, and dark skin, with some individuals probably having light coloured, even blue eyes.  Dark skin was likely to have been a feature of earlier, Upper Palaeolithic fore-bearers. Despite low UVR levels, they found other ways of dealing with poor vitamin D production. Their diet may have compensated for the low UVR.

A separate population appeared in Eastern Europe, defined as EHG (Eastern Hunter-Gatherer) and an SHG (Scandinavian Hunter-Gatherer) admixed between the two groups.

Mesolithic Europe

These were the last of the European hunter-foragers who needed to adapt to climatic and environmental changes of the Holocene period. The Younger Dryas (12,900 to 11,700 years before present) represented a return of bitterly cold conditions before the rapid commencement of the Holocene. See the below trend in temperatures. Temperatures in Greenland rose by 10 C in only a decade.

Flora change followed this rapid rise in annual temperatures. During the Earlier Mesolithic, tundra grasslands were gradually replaced by birch scrub, followed by forest. Species to reach Britain included birch, alder, pine, and alder. During the Later Mesolithic, temperatures continued to rise. Lime (Linden), hazel, hawthorn, blackthorn, ash, elm / wych elm, followed. Beech probably didn't arrive until the end of the Mesolithic period. It had previously been speculated that Late Mesolithic lowland Britain would have been covered by one continuous wildwood canopy. However, pollen analysis has suggested some areas of open grassland, possibly kept open by the ruminations of large herbivores such as aurochs (wild cattle), bison, red deer, and roe deer. There has been some suggestion that the hunter-gatherers may have been managing these areas, and extending them with fire. This may have improved the regeneration of hazel (hazel nut was likely to have been a very important food source), and better, more open hunting conditions, where ungulates herd together in the open.

Lithics

The knapped flint and stone tools of the Mesolithic are largely characterised by the production of very small blades known as microliths. These would often be notched into small geometric shapes. Arrows were likely composite, with a microlith point, and small microlith barbs being glued and / or bound along the shaft behind that point. Microliths may have had further uses as microburins (piercers or borers for hide clothing etc) or as scalpel blades for working wood, bone, and antler. A further stone tool associated with this period is the Mesolithic tranchet axe head.

Antler working

Star Carr is a well known archaeological site in North Yorkshire that dates to between 11,280, and 10,500 years before present. This places it shortly after the end of the Younger Dryas during the Earlier Mesolithic.

Magdalenian - out of the Big Freeze

The Magdalenian Culture of Palaeolithic Europe follows the big freeze of the Last Glacial Maximum and dates from 17,000 to 12,000 years ago. Climatic conditions continued to remain grim, but a warmer interstadial known as the Bølling–Allerød, lasted between 14,690 and 12,890 years ago. The Magdalenian first appears in France, where it is contemporary with the Epigravettian Culture of Italy and further east. The founder population of the Magdalenian descends from earlier West European groups, including West Gravettian / Solutrean, and Western Aurignacian.

Magdalenian yDNA haplogroups so far discovered are I, and one HIJK

Magdelanian  mtDNA haplogroups all U (several U8b and one U5b).


One cluster at El Muron was found to be related to West European Aurignacians of the Goyet caves of Belgium, from 20,000 years earlier, supporting that the Magdalenians were descended from earlier Upper Palaeolithic hunter-gatherers of western Europe. However, later Western Hunter-Gatherers of the Mesolithic, were closer related to the more south eastern groups of the Epigravettian Culture.

Long, regular blades were struck from prepared, carinated cores. Later phases are associated with harpoons made of antler, ivory, and bone. Main prey species on the Continent was reindeer, although other groups such as those in Britain, focused on tarpan (horse). Red deer and ibex were also targeted. One study found little evidence of salmon nor saiga antelope in the diet of a Magdalenian woman. Another study has found evidence of consumption of wild plants and bolete mushrooms.

This study found that the diet of Magdalenians was more varied, with more abrasive foods than those of earlier hunter-gatherers in Europe.

The Cannibals of Gough's Cave.

Just as the climate began to improve circa 14,700 years ago, some Magdalenians sheltered in Gough's Cave Somerset. Batons and tools were left within, along with horse bones and human remains. Tarpan seem to have been their main prey, and they may have been following the horse herds north into Britain as the climate improved. The human bones had been treated in much the same way as the bones of food prey. Cut marks and incisions suggest that they were stripped of flesh, and this discovery has led to much debate about possible cannibalism. Human crania appear to have been modified into drinking cups:

'The skulls were scrupulously cleaned of soft tissue shortly after death. Marks show cutting of the lips, cheeks and tongue, and extraction of the eyes.

Then the bones of the face and the base of the skull were carefully removed. Finally the cranial vaults were meticulously shaped into cups.'

It has been suggested that a British Late Magdalenian Culture existed, called the Creswellian Technology, dating 12,000 to 10,000 years before present that is similar to a Hamburgian Culture on the Continent.


Gravettian - into the Big Freeze

The Gravettian overlaps the late Aurignacian, dating from circa 33,000 years ago, and surviving until 20,000 years before present. This included the coldest peak of the last Ice Age, the Last Glacial Maximum around 24,000 years ago until 18,000 years ago. These really were Ice Age Europeans. Travel as far north as Britain must have taken place during warmer intervals. Otherwise the Gravettian is found in a band across Western Eurasia, which stretches from Portugal and the Basque region, through France, Germany, Czech republic, as far east as Georgia and South Russia.

Gravettian yDNA haplogroups so far discovered are CT, I, IJK, BT, one C1a2 and one F.
Gravettian mtDNA haplogroups overwhelmingly U (mainly U2 and U5), with one M.

The Late Gravettian developed into a culture in France and Iberia, that we call the Solutrean. Meanwhile in the south east of Europe, from the Italian peninsula across the the Western Steppe, it diverged into the Epigravettian culture, which overlaps for much of its range with the Mammoth Steppe.

We identify a genetic ancestry profile in individuals associated with Upper Palaeolithic Gravettian assemblages from western Europe that is distinct from contemporaneous groups related to this archaeological culture in central and southern Europe4, but resembles that of preceding individuals associated with the Aurignacian culture. This ancestry profile survived during the Last Glacial Maximum (25,000 to 19,000 years ago) in human populations from southwestern Europe associated with the Solutrean culture, and with the following Magdalenian culture that re-expanded northeastward after the Last Glacial Maximum. Conversely, we reveal a genetic turnover in southern Europe suggesting a local replacement of human groups around the time of the Last Glacial Maximum, accompanied by a north-to-south dispersal of populations associated with the Epigravettian culture. 
A previously unknown population replacement event that was archaeologically invisible, occurring during the peak of the Ice Age.  This DNA was then passed on via the Solutrean people to the following Magdalenian people.

These people buried their dead more frequently in graves than did the Aurignicians.  The grave of three male teenagers at Dolní Věstonice was particularly enigmatic. The person on the left, has a hand placed over the stomach of the middle character, where red ochre had been applied. The central person had a curved spine, diagnosed as caused by chondrodysplasia calcificans punctata (CCP).  The body on the right had been placed facing down. Red ochre had also been applied to the heads of all three.

For their last journey, the individuals have been richly equipped with headdresses made of the teeth of the arctic fox (Vulpes lagopus), wolf (Canis lupus), and unidentified large predators. In the mouth of DV15, a mammoth ivory disc was placed.

Prey appear less restrictive than for the earlier period which focused on reindeer. The Gravettians hunted deer, mammoth, hares, lions, bear, foxes. Rather than use split antlers as points, they used flint blades known as Gravettian points. There is evidence that the Gravettians had access to bows and to the spear thrower. Furthermore, they may have had the first domesticated animal, the dog.

Conclusion

The Gravettians entered Europe in the long, slow run up to the Last Glacial Maximum, and endured much of it. Although they inhabited a vast region of Western Eurasia, their culture remained constant, albeit with some divisions between west and east. The Pavlovian Culture developed in the east as mammoth-hunters.  The Gravettians often buried their dead with much ceremony, wearing seashell beads, ivory, and animal teeth. They were successful and adaptive Ice Age hunters, preying on deer, reindeer, mammoth, fox, hare, hyena, wolf, seal, and foraged for shellfish. They lived in circular, semi subterranean shelters, but were mobile. Skilled artists with cave paintings and carved ivory. They tipped projectiles with flint blade points, and may have used bows, boomerangs and atlatls. Nets were woven, and lamps of stone used. They may have developed an early relationship with dogs.

During the Last Glacial Maximum, although their artefact culture continued, there was a population replacement event by people closer related to their Aurignician predecessors.  These later Gravettians fostered the Solutrean Culture in France and Iberia, and the Epigravettian culture of the east and south east.
