Thoughts in understanding ancestry DNA

The above map shows genetic distances between different human populations around the planet.  Look how tightly the Europeans cluster.  Razib Kahn recently blogged on just this subject.  The fact of the matter is that the greatest diversity exists between populations outside of Europe, particularly within Africa, and between African and non-African populations.  However, we obsess over tiny differences within European populations, when in truth, most Western Eurasians are very closely related.  We share ancient ancestry from slightly varied mixes of only three base ancestral groups, with the last layer arriving only 4,300 years ago.  This obsession in the Market drives DNA to the consumer businesses to largely ignore non-European diversity, and to focus too closely on differences that blur into each other.

The above image is from CARTA lecture. 2016. Johannes Krause of the Max Planck Institute. It shows the currently three known founder populations of Europeans and their average percentages.

However, at the same time the new Living DNA service seeks to zoom in closer on British populations, attempting to detect ancestry percentages from such tiny zones as "East Anglia".  They appear to be having a level of success with it as well, although that blurriness, that overlap and closeness of populations in Europe gives problems.  Germans are given false percentages of British, Some Scottish appear as Northern Irish, and the Irish dilute into false British areas.  However, I've seen enough results now to suggest that it is far from genetic astrology.  They get it correct to a certain level, particularly for us with English ancestry.  Ancestry DNA customers expect perfection.  I don't think that we will ever get that from such closely related populations at this resolution, but it does provide a new genealogical tool that can point us into some revealing directions.

Above image.  My Living DNA Map.  Based on my recorded genealogy, I estimate 77% to 85% East Anglian ancestry over the past 250 years or so.  Living DNA at Standard Mode gave me 39%.  I'm impressed by that.  That a DNA test can recognise even at a 50% success, my recent ancestry in such a tiny zone of the planet.  I have doubts though that this sort of test will ever be free of errors, and mistakes.  The safest DNA test for ancestry is still one that is based on more distinct populations, and outside of Africa, that can be as wide as "European".  23andMe for example in their "Standard Mode" (75% confidence), assign me 97.3% European, and 0.3% Unassigned.  That is a pretty safe result.

Autosomal DNA tests for ancestry, particularly for West Eurasian (European and Western Asia) descendants, are not reliable at high resolution.  If you want to get really local, then sure - do it.  However, only use the results as an indication, not as a truth.  Populations in Western Eurasia are closely related, and share recent common descent.  There has been a high degree of mobility and admixture ever since.  Some modern populations tested do not have a high level of deep rooted local ancestry in that region.  They overlap with each other.  Keep researching and meander through different perspectives of what your older pre-recorded ancestry could have been.

What have the Romans done for us?

I can feel Spring in the air.  So, day off from work, I decided to take a field trip.  Wasn't sure where to when I hit the road, but I ended up at Burgh Castle, the ruin of a Roman Fort of the Saxon Shore.

Information board at Burgh Castle.

Traditionally, the Roman Shore Forts of South-East Britain were seen as Late Roman defensive structures, to protect Roman Britain from attack from barbarians from the other side of the North Sea, outside of the Empire.  This remains a valid view, although I remember attending a lecture by a local archaeologist many years ago, that argued that these shore forts, were a little odd.  With civilian activity inside the forts, and not particularly very defensive.  He was arguing that rather than protect Roman Britain from invasion by Anglo Saxon pirates, they were intended to control and tax heavy commerce across the North Sea.  No I'm not going to take sides, perhaps there was an element of both intentions.

I personally also like to see this fort as a sort of 4th Century AD immigration control.  My mother's 18th and 19th Century ancestors are so strongly clustered nearby at the Reedham area, that I can't help but imagine that at least some of her ancestors lived in East Norfolk way back into the medieval, and perhaps some of them rowed passed this recently decommissioned shore fort during the early 5th century AD.  I imagine them jeering at the now abandoned post of the Empire, as they rowed past.  Arriving into Britain, with fealty free land just for the grabbing, a land of opportunity for rural self sustaining farmers from the Continent.

The view down on the Yare and Breydon Water from Burgh Castle.  Much of this would have been flooded during the 4th Century by higher sea levels and the absence of drainage.

From a population genetics point of view, we are usually told that the 360 year long period of Roman Britain contributed little to our present day DNA.  More important was the contribution of the Early Bronze Age, that carried DNA from the Eurasian Steppes, followed perhaps by the Anglo-Saxon / Danish / Norman Medieval immigration events that followed the collapse of shore forts such as this one.  It is usually suggested that because actual migration from Rome was sparse, and troops were scattered from all over the Empire, that there was little impact on the late prehistoric British genome.

However, whenever an odd haplotype turns up in an old British family, including for example, my own Y-DNA that appears to have originated from the area of present day Iran or Iraq, someone will suggest that it could have arrived during the Roman Empire.  Indeed, in some cases they may well have made their way into North west Europe, even to the British Isles during that time.  Trade and exchange across Western Eurasia was thriving.

I give you Burgh Castle, Norfolk.  They may have built it in order to keep some of my ancestors out.

Medieval Mobility, DNA tests, and the East Anglian

My last post on the Norfolk 16th century surname study has made me look at my medieval East Anglian roots a little differently.  It suggests that there may have been a fair amount of mobility and migration in East Anglia, and from outside, from both Northern England, and from the nearby Continent.  Although current commercial autosomal DNA tests for ancestry are clearly contradictory, behind them lays a common pattern.  My auDNA is little bit more similar to people living on the Continent, in places like France, Belgium, Netherlands, Germany, Denmark, and also further to the south - than it is for most British testers.  This is despite my known English family history and recorded ancestry.  These commercial DNA tests usually claim to investigate your family ancestry over the past 250 - 500 years only.  I'm convinced that is untrue.  I can't help but see population background, and shared patterns from testers that have no known, or little known migration or admixture in places such as England, and Northern France.  These appear to represent older migration and population admixture events that are shared across local genomes.

However, maybe there is something that these tests are telling me - but only after taking into account to the results of other British testers.  I now believe that I may have underestimated mobility around East Anglia and England between the fourteenth and seventeenth centuries - that precedes any of my recorded ancestry.  I also feel the need to reassess Continental migration to East Anglia.  It appears it was not all urban or bourgeois.  The Anglo-Saxon fifth century AD may have marked the most significant migration event to south east Britain, but I know believe that I have underestimated how much migration and exchange has occurred across the North Sea ever since.

Focusing first on movements within East Anglia, and England, I have in my last post,  Norfolk surnames in the sixteenth century, provided locative surname evidence.

Let's look at some more historical research.

"Considerable personal mobility existed from the later Middle Ages.  From the mid fourteenth century the loosening of seigneurial bonds allowed English people to become even more mobile.  Landlords complained that tenants were deserting their holdings for better land elsewhere and that servants and labourers were seeking higher wages from other employers.".

"From the sixteenth century, migration and personal mobility becomes better documented.  A study of tax records for Towcester in Northamptonshire showed a considerable turnover of the population between consecutive years.  In 1525 47 of the 278 men taxed in the previous year had left.  This unusually full source shows that six of the 47 had died and 41 had migrated.  This represents a turnover rate of 16.9 per cent a year - higher than any other communities in pre-industrial England.".

The continuity (and discontinuity) of surnames over a period of time indicates the movement of individuals and families with the same surname in and out of the community.  The small 'close' village of Glynde (population 216 in the 1801 census) lies three miles from the East Sussex county town of Lewes.  Between 1558 and 1812 out of 444 different surnames that appeared in the parish register (excluding people whose only connection with the village was to marry in its church) 261 surnames (58.8 per cent) occurred only once and 71 per cent were found only during a period of 25 years or less.".

So, maybe I need to discard ideas of my mother's tight cluster of recorded ancestry as having been so localised for so long.  Although, the density of the cluster does suggest that she probably have some direct ancestry in the Reedham area of East Norfolk for a very long time, perhaps back to the early medieval, there is also a good probability that her medieval ancestry stretched much further across the region, England, and to the Continent.  Indeed, her known ancestral proximity to the coast and a tidal navigable river makes that Continental ancestry more likely.  For my father's ancestry - the majority recorded East Anglian, but with known ancestry going back to Oxfordshire, Berkshire, London, and the East Midlands, this might be even more the case.

Norfolk Surnames in the Sixteenth Century

I spent too much money today on reading materials.  I was delighted to find a used copy of The Norfolk Broads A landscape history by Tom Williamson 1997 (Manchester University Press).  I had a copy of this excellent landscape history when it was published, but unfortunately lent it out, and never saw it again.  A brilliant book for tying my mother's East Norfolk ancestors to their ancestral landscape.

The April 2017 edition of Current Archaeology magazine has an interesting article on an excavation of an Iron Age site in Fenland, and is celebrating their 50th anniversary of publication.

The real treasure of today's book shop excavation however, was an old booklet published in 1969 by Leicester University Press in their Department of English Local History Occasional Papers.  It is entitled Norfolk Surnames in the Sixteenth Century by R.A McKinley.  Flicking through it's pages on the way home, sitting on the bus, I was well, almost mind blown - as some of the conclusions knocked down some of my preconceptions of my Norfolk ancestry and heritage.  An old, yellowing booklet that I've never heard of, found on a shelf in a second hand book shop in Norwich.

The book draws on surnames recorded in the County of Norfolk, during the 16th Century AD.  It uses as it's sources several returns, and rolls particularly a military survey, and subsidy roll from between 1522 and 1525.  I want to share at least some of the key points from two chapters of "Norfolk Surnames in the Sixteenth Century": 1) Surnames derived from localities in Norfolk, and 2) Locative surnames originating outside Norfolk.

1) Surnames derived from localities in Norfolk

  • The chapter begins by discussing the problems of using locative surnames in a study.
  • "The two main sources used for this study list 739 persons bearing locative surnames derived from places within Norfolk.  Of these, only 23 were living at the places from which their names were derived.".
  • A table then shows the distances of the persons (still within the County of Norfolk) with these locative surnames from origin.  23 were still at the place of origin, 81 were still within 5 miles of it, 123 were within 6 - 10 miles away, 239 were 11 - 20 miles away, 151 were 21 - 30 miles away, and 122 lived over 30 miles from the locative place of origin.  However, these are the locative surnames that still remain in Norfolk, that appear to have an origin within the County.  Many more would have crossed county boundaries into Suffolk, Lincolnshire, etc.
  • "It seems probable from this evidence, however, that most Norfolk families must have changed their place of residence at least between the period when surnames became hereditary, and the early sixteenth century.".
  • There was no pattern to suggest a large migration from any one part of the County, to another.

2) Locative surnames originating outside Norfolk

  • "In the two main sources, there are 1,260 persons bearing surnames which can be derived with fair certainty from places in England, but outside Norfolk".
  • The author then discusses possible biases, for example, some parts of England appear to have generated more locative surnames than others.  It also suggests that about a third of all English surnames are locative, and proposes a rough approximation, that this could "be about 2,500 persons of outside origin amongst the total of about 18,000 listed in the two main sources, or rather more than 13 per cent".  This suggests quite a few people had been moving from other parts of England, into Norfolk between the 13th and 15th centuries AD.
  • Where were they from?  The two main contributors were the neighbouring counties of Suffolk and Lincolnshire. Some had simply moved from close to the Norfolk county boundary.   
  • Cambridgeshire, another neighbouring county, for some reason contributed far fewer.  The East Midlands was also, surprisingly, not a major contributor of locative surnames in 16th Century Norfolk.  There were no locative surnames from Wales.
  • Here is another surprise, Yorkshire turned our to be a common origin - equally spread through the three ridings.  Each riding of Yorkshire had contributed about 40 persons in Norfolk with locative surnames.  The author does point out that Yorkshire is a big county, and is particularly rich in locative surnames, however: "it is evident that there must have been considerable movement from Yorkshire to Norfolk.  Yorkshire surnames are distributed throughout Norfolk in the early sixteenth century.  They are not particularly concentrated in ports or coastal areas, and indeed, are as widespread in central Norfolk, well away from the sea, as in other parts of the county.".
  • There was also a notable contribution of locative surnames from NW England - Lancashire, Cumbria, and Westmorland.
  • The distribution of these surnames was by no means urban based.  Yamouth and Norwich had lower concentrations than the average.  These migrations look more rural.
  • There were very few surnames of any origin type that could be safely regarded as Welsh.
  • There were very few surnames of any origin type that could be safely regarded as Scottish.
  • The author then moves on to records of other foreign born aliens.  I am aware of the influx of Dutch and Flemish religious refugees, into the City of Norwich during the early 16th Century, however, here I learn something new.
  • "there was certainly a considerable migration of aliens into Norfolk, and foreign immigrants came to reside in many Norfolk villages, not merely in a few ports or large towns.  In 1436, for example, when many aliens took oaths of allegiance, 146 persons who took oath are noted as living in Norfolk.  This was not the whole number of aliens in Norfolk...".  A list in 1440 for example, lists 192 aliens residing in Norfolk at 62 different places.  The author feels that those 15th Century records understate the real percentage of immigrants living in Norfolk at that time.
  • The Continental immigrants did not bring in many new surnames.  Many had no surname listed, or had adopted local surnames.  For example, immigrants listed at Norwich in 1440, included persons by the surnames Rider, Johnson, Forest, Skynner, Couper, Bush, Goldsmyth, and Glasier.  Some surnames marking their nationality did survive in 16th Century Norfolk, such as French, Ducheman, Briton / Brett (Breton) etc.

Brancaster, a North Norfolk village.

In summary, what this book has taught me today:

  1. Many families, despite our ideas of the dying fuedal system, were moving around East Anglia, and even England between the 13th and 16th centuries.
  2. There were relatively few people in 16th century Norfolk, with origins in Scotland, or Wales, and perhaps few from the nearby East Midlands or Cambridgeshire.  However, there was migration down from Northern England, particularly from Yorkshire, but even from NW England.
  3. There were also migrations, from the nearby Continent, and these migrations (and the above Northern English) migrations were not strictly urban.  They reached many villages.

Celebrating my Steppe and Beaker Ancestors

The Pontic Steppes, by Terpsichores [CC BY-SA 3.0], via Wikimedia Commons

I've previously dealt with my Ice Age hunter-gatherer ancestry, as indicated by DNA test result calculators, and with my Neolithic Farmer ancestry.  That leaves the third major late prehistoric contributor to the Western European Genome.  The most recent, and perhaps the most character defining - the Chalcolithic Steppe pastoralists or Yamnaya element.

My Yamnaya ancestors

Y-DNA haplogroup enthusiasts of European descent absolutely LOVE this one.  This is because the majority of men of Europe have a Y haplogroup that arrived here from the Eurasian Steppes with this immigration wave.  All of those R1a's and R1b's.  My personal Y haplogroup didn't!  But I'm a nonconformist with a nonconforming Y-DNA haplogroup. Populations such as the modern Irish men, on the western edge of Europe, can trace most of their R1b haplogroups to the Steppes!  That some of of the earlier hunter-gatherer and Neolithic DNA here earlier still survives in most of us, suggests that this long migration consisted mainly of men.  My mtDNA haplogroup though, as usual, is atypical - because H6a1 is one of the few maternal lineages in Europe that DOES also trace back in ancient DNA samples to the Yamnaya pastoralists.  So, I DO have a Steppe haplogroup, only through my motherline.

The Eurasian Steppes have been a super highway of people, goods, culture, and genes, for thousands of years - linking Asia to Europe.  A long, sometimes narrow corridor of natural grasslands.  The wild ancestors of the domestic horse lived there.  They had adapted to life in harsh environments such as this.

The Yamnaya themselves appear to have been admixed between different earlier Ice Age populations, including Caucasus Hunter-Foragers, East European Hunter-Gatherers, and the enigmatic Ancient North Eurasian Siberian ghost population, that were also among the ancestors of Native Americans.

One of the successes of the Steppe pastoralists, was that they embraced the horse.  They rode their horses, enabling them to control larger herds of sheep, goats, horses, and cattle.  That was one element of success.  They also utilised the wheel, and built the first wagons and carts to be pulled by those horses and ox.  This gave them a greater mobility, to move their livestock seasonally to further pastures.  Biologically they were also adapting to a dairy based diet with lactose tolerance.  Finally, they embraced the new metallurgy of copper, and then bronze working.  The raw materials of this new technology shifted along the Steppes, and through their contact with many peoples, including with the new towns and kingdoms south of the Caucasus.

Another factor that needs to be considered, is that according to some scholars, they brought the Indo-European group of languages to Europe, which are ancestral to most European languages today.

Recent evidence has been produced that suggests that some of the pastoralists carried a plague virus, transmitted from a Central Asian origin.  A new hypothesis is that they may have unintentionally passed this plague onto the Neolithic Europeans, weakening their populations and societies.

Whether this hypothesis ever substantiates or not, the archaeological and genetic evidence is that the Second Millennium BC saw many of these Steppe men (and my mtDNA ancestor) spill westwards into Copper Age Europe.  After 2,900 BC, their arrival, and fusion with local populations and traditions may have inspired the Corded Ware Culture of Central and Eastern Europe.  My mtDNA haplogroup H6a1a suddenly appears in Central Europe, associated with this culture.

These horsemen of bronze, or their descendants didn't stop the Westward advance.  Within a few hundred years, they also dominated Western Europe.  There, their arrival may have spawned another fusion culture - the Bell Beaker.

Above image, bell beaker burial exhibited in the British Museum.

My Bell Beaker Ancestors

The Maritime Bell Beaker Culture may have originated when these horsemen arrived in Iberia.  When I was a keen amateur archaeologist and field walker, I'd feel a lot of contact with them.  Many, if not the majority of the struck flints that I recorded in Thetford Forest were considered "bronze age".  I would also survey the surviving round barrows in the forest, and look for unrecorded examples.  I also spent a week with Suffolk archaeology, studying new aerial reconnaissance photographs, and helping to chart the soil and crop marks of long ploughed out barrows.  I had no idea then, that this barrow burial tradition had actually been brought from the Steppes of Eurasia.  Archaeology at the time didn't see the Bell Beaker as the arrival of people.  They saw it as a cultural transference from Iberia.  Genetics is now telling us differently.

The Maritime Bell Beaker Culture of the Early Bronze Age appears to have gradually evolved by the beginning of the Iron Age, into what we traditionally call the Atlantic Seaboard Celtic Culture, so strong in places such as Ireland and Scotland.  Yet, most Irishmen carry the Y haplogroup R1b SNPs such as L21. A recent Irish DNA Study revealed that they found the modern Irish not only a fairly homogeneous population, but that it had its roots, particularly on male haplogroups, firmly in the Pontic and Caspian Steppes of what is now Ukraine and Southern Russia.  They also studied the DNA from remains of Bronze Age, and the earlier Neolithic people that lived in Ireland, and pronounced them to have had different origins.  The earlier, Neolithic Irish largely descended from population that originated in SW Asia.

http://www.pnas.org/content/113/2/368.full

Here in Britain also, the majority of men carry R1b Y-DNA.  I have a Steppe mtDNA haplogroup from my mother.  Additionally autosomal DNA calculators suggest that maybe circa 30% of my Copper Age ancestors were Steppe.  However, where did my Steppe ancestry come in?  The obvious would be from British Celts - but that is an unsafe assumption.  My recorded ancestry is totally SE English, and strongly East Anglian.  My autosomal DNA "flavour" though is atypical for a Brit, and is unusually Continental, with a tertiary pull from Southern Europe, that I can't explain.  If many of my ancestors two thousand years ago actually lived outside of the British Isles, most likely on the Continent, then they could have inherited much of this Steppe there.

Ultimately of course, I know where maybe a third of my ancestors lived 4,000 years ago.  They were pastoralists on the windy Pontic Steppes, looking to the west, and wandering, what opportunities lay there?

Celebrating my Neolithic Ancestors

Image above, last year, holding an artifact from the Neolithic Tomb of the Sea Eagles in Orkney.

Today in this post, I am celebrating my Neolithic heritage.  Another ancestral genetics enthusiast pointed out that rather than Anglo-Saxon, for a Brit and North West European, I actually had indications of enhanced Neolithic Farmer ancestry on most ancient DNA calculators (more on that below).  I was actually quite pleased to have that pointed out, and this post explains why I love the idea of being a modern Neolithic Man.

I remember being fascinated by the past as quite a young child.  On holidays across the British isles, I craved nothing more than visits to castles.  At home in Norwich, I'd haunt the local museums.  However, a love of the Neolithic took hold during my twenties. First, a fishing and drinking tour of Ireland with my brother, took me to the Newgrange Passage Grave site in the Boyne Valley.  Awesome impact.  Then several years later, I picked up the broken butt end of a Neolithic polished flint axe head on farmland behind my cottage.

The above photo is an image of another broken Neolithic flint axe head that I recorded during a surface collection survey many years later in Thetford Forest.

This eventually pulled me into a phase of looking for more prehistoric flint, which I later formalised into the Thetford Forest Survey.  During that period, in collaboration with the Forestry Commission, Norfolk Archaeology, and Suffolk Archaeology, I recorded thousands of struck flint and ceramic artifacts - many from the Neolithic.

Above image taken at the Castlerigg Stone Circle in Cumbria in 2006.

Any chance that I got, I'd also visit Neolithic sites across the British Isles - and continue to do so, hence last year I had a cycling tour of many late prehistoric sites in Orkney.  Absolutely love the Neolithic.  Even though an atheist, I have to confess that some of these sites give me a special vibe.  I have half-seriously told neo-pagan friends, that If I had to choose some gods, Then maybe they would be those of the Neolithic.  Something about the remote sites.

Our New Understanding of the Neolithic of Europe

What I really want to write about here though, is how recent population genetics, over the past ten years, is transforming how we see the Western Eurasian Neolithic.  Archaeologists had long pondered, our relationship to the British Neolithic people, and going further back and in turn - their relationship to the earlier Mesolithic hunter-foragers of the British Isles.

What recent research of both ancient and modern DNA has so far revealed is that after the last Ice Age, hunter-foragers moved up to Britain from Southern Europe.  Meanwhile, new cultures and economies were developing in the Middle East of SW Asia.  Across the Fertile Crescent, that ran up the Levant, East Anatolia, eastwards, then down the fertile valleys of the Tigris and Euphrates river valleys - people started to settle, domesticate wheat, barley, goats, sheep, cattle and pigs.  They started to farm for the very first time.  This was the Neolithic Revolution.  The first fired ceramics - pottery was added to the recipe, along with polished stone tools.  Eventually these populations also absorbed the very first metallurgy, literacy, and town building - falling into the southern half of those river valleys in Mesopotamia.

Image above - Standing Stone at Stillaig, Argyll, Scotland.

From the Levant and Anatolia, both along the Mediterranean, and direct across the Balkans by land, Neolithic culture and farming technology spread westwards and northwards across Europe.  Population genetics now tells us that this WAS carried by people.  It was not just a transfer of culture and artifacts.  DNA from South-West Asia was strongly carried across Europe.  The Neolithic farmers were a people, with roots in the Near East.

What happened to the old European hunter-foragers?  It seems a mixture of displacement and admixture.  As the Neolithic Revolution rolled across Europe, it did pick up some hunter-gatherer DNA.  However, few of the male haplogroups.  By the time that the First Farmers reached the British Isles, they would have had an ancestry mixed between Near East Asian and European hunters.  Without a doubt, brides and perhaps slaves were taken along that long route from Anatolia to Britain.  This pattern perhaps continued when they reached the Irish and British Isles, and confronted some of the last hunter-gatherer populations of North West Europe.

Image above.  Ring of Brodgar, Orkney.

All of this was fine.  The British Isles were settled by Neolithic peoples around 4,100 BC.  I've seen many of their monuments, studied excavation reports of their archaeological sites, and held many of their flint artifacts.  It was a dominant culture here for two thousand years.  Religious systems may have come and go.  They erected so many monuments here that still survive.  Causewayed enclosures, long barrows, cursuses, henges, monoliths, cairns, standing stone circles, timber circles, mounds, Silsbury Hill - and of course, the internationally renown Stone Henge.  However, we now realise that they carried much DNA from South West Asia!

They must have thought that they, their beliefs, and their social systems would last until the end of time.  We currently think that their populations and farming declined towards the end of their period.  There is a little evidence that they may have been subject to plague from Asia.  This might have weakened them for the next invasion and displacement.

The arrival of the Sons of the Steppes - the Beaker

I'll write more about these guys in a later post.  Around 2,100 BC, a new people and culture turned up in the British Isles.  Whereas the Neolithic peoples had largely originated in SW Asia, south of the Caucasus (with some European hunter-gatherer DNA picked up on the way), these new arrivals largely originated to the NORTH of the Caucasus, on the Pontic and Caspian Steppes.  Their Steppe ancestors perfected the domestication of the horse, bronze metallurgy, and wheeled wagons. The founder Steppe population has been identified by archaeologists as the Yamnaya.  They rolled into Eastern and Central Europe, where their arrival appears to have spawned the Corded Ware Culture.  Their descendants in turn appear to have spawned the Bell Beaker Culture in Western Europe.  In turn, the Bell Beaker appears to have developed into the Atlantic Seaboard Celtic Culture of fame and fashion.

The Eurasian Steppe male haplogroups absolutely dominate present day Europe.  However, again, they appear to have absorbed some women with Neolithic and even earlier Hunter-Gatherer populations into their genome.

The Three Way across Europe

Across modern Europe, we are a mixture of three distinct late prehistoric populations or genetic out-layers - from most recent to oldest:

  1. Yamnaya or Steppe
  2. Neolithic Farmer
  3. Western Eurasian Hunter-Gatherer

The above image is from CARTA lecture. 2016. Johannes Krause of the Max Planck Institute.  All Rights Reserved.

As can be seen above, some Neolithic DNA has survived in present day Europe.  It is strongest in Southern Europe.  Yamnaya ancestry is more of an influence in Northern Europe, although, old Hunter-Gatherer survives strong in the Baltic Republics.  The modern population closest to our Neolithic ancestors are the Sardinians.  So close, that when Ötzi, a frozen preserved Neolithic body was discovered in the Alps, his DNA was seen as so similar to present day Sardinians, that some incorrectly suggested that he had travelled to the Alps from Sardinia!

Basal-rich

The Basal Eurasians are a hypothetical "ghost" population derived from DNA studies.  It is suggested that they splintered from other modern humans 45,000 years ago, presumably outside of Africa, somewhere around the Middle East.  They significantly contributed DNA to the Early Neolithic Farmers of the Fertile Crescent and Anatolia, and consequently, on to all of us modern West Eurasians.

My Neolithic ancestry appears to be strong, for a Brit.  However - my Neolithic ancestors may not have all - or even at all, have lived in the British Isles.  My Neolithic ancestry may have been picked up along the way, across Europe, by ancestors as they travelled across Western Eurasia.

A visit to Sutton Hoo - Kings of East Anglia

A day off from work, and I had promised myself that I was going to get out and tick off a job that's been waiting some time.  A visit to the Anglo-Saxon ship burial site at Sutton Hoo in Suffolk.  Maybe I should have checked the weather forecast first.  I would have seen that Storm Doris was going to hit East Anglia.  Never mind, I got there and back in one piece, having circumnavigated a number of fallen trees.  Luckily, I arrived before the centre shut it's gates.  I was advised not to walk to the mounds, for fear of windfall - but only mad dogs and Englishman.  At least it was quiet.

The nature of these mounds was revealed back in 1938, when the land owner, Mrs Edith Pretty, commissioned an investigative excavation.  The burials have included whole ships, warriors, swords, grave goods from all over AD 7th Century Europe, and a horse.  The interpretation is that it was the burial site of the Kings of East Anglia during the 6th and 7th centuries AD.

The 1938 excavation revealed the soil marks and iron rivets of a burial ship.  Built in a clinker design, it appears similar in many respects to ship burials in Sweden, only at least two hundred years before the classic Viking examples.  Initially Mrs Petty and her team thought that they had found a Viking ship burial, but at it's centre - although there were no surviving human remains, they found a treasure of grave goods that suggested an Anglo-Saxon origin.  Nothing like it had been found before.

Excavations of the mounds have also revealed that treasure hunters and grave robbers had removed many artifacts during previous centuries, and caused much damage.  One reported dig in another mound here, during the mid 19th Century reported that they found no treasure, just lots of iron rivets - that they sold to the local iron smith to produce horse shoes!  This suggests at least one other ship burial at this site.

Mrs Pretty lived in a house close to the mounds, that is partly open to visitors.  Artifacts, letters, photos of the 1938 dig are displayed in the house.

The original Sutton Hoo Treasure is held in the British Museum in London.  I've seen it several times, but this was my first ever visit to the dig site itself.

Above, a proposed reconstruction of what the chamber in the ship may have looked like at the time of burial.  Although no human remains survived, it is speculated that this was the burial of King Raedwald, who ruled as King of the East Anglians AD 599 to AD 624.  Raedwald is considered the most powerful early 7th Century Anglo-Saxon king in the British Isles.  He belonged to the Wuffinga Dynasty of early East Anglian royals.  Below is a replica reconstruction of the famous ceremonial helmet found in the 1938 ship burial.

The helmet appears styled on ceremonial helmets worn by Roman generals in the late Western Roman Empire.  It has been suggested that the craftsmanship appears Swedish.  The Swedish links have led some to speculate that the Wuffing Dynasty may have had links to Sweden.

More replica reconstructions from the treasure that can be seen at the Sutton Hoo visitor centre.

Grave goods appear to have came from all over contemporary Europe - from Ireland, France, the Eastern Mediterranean, and Scandinavia.  This demonstrates the ability of the East Angle elites to trade goods from far away.
