Revision of Late Prehistoric Brecks, East Anglia

Whilst rebuilding the Thetford Forest Archaeological Survey website, it occurred to me that when examining the late prehistoric Brecks NCA (National Character Area), it is important that we do not divide the district from the nearby Fen-edge. In the sandy, drought-prone soils of the Brecks, water has always been important. Historical parish boundaries in Breckland often stretch out to water supplies, enabling shepherds and herders to reach vital watering spots for livestock. This importance was perhaps equally important during late prehistory. Any forms of settlement most likely concentrated on the river valleys, and along the fen-edge of the Brecks. Just as they still do today.

The rivers of the Brecks flow westwards to discharge into the waterways of the Fen wetlands. The edge of the Fens, was likely attractive to human occupation, then and now. This is supported by the archaeological record.

I have produced this map, highlighting wetlands, rivers, meres, and pingos, known to have existed during Late Prehistory. The red star represents the Grimes Graves Late Neolithic flint-mine site. Here I am showing the rivers and waterways of that period as an extension of the yellow highlighted fen-edge. This is nothing new, but I want to reinforce, that to understand the late prehistory of the Brecks from the Mesolithic through to the Iron-Age, it important not to divide it from the wetlands of the Fens.

The Post-Glacial Landscape of the Fens (c. 10,000 – 6,000 years ago) Early to Mid Mesolithic.

At the end of the last Ice Age, the area wasn't a wetland but a dry, forested valley. The Fens were a very different, dry environment for the visiting hunter-foragers of the Earlier Mesolithic. The rivers we now recognise as the Great Ouse, Nene, and Welland were inland tributaries flowing towards a coastline much further north. As the climate warmed, and sea levels rose, Britain separated from continental Europe. By approximately 7,800 years ago, a major marine transgression began to absorb the dry, forested valleys into a coastal body of water.

The Rise of the Wetlands (c. 6,000 – 2,000 years ago) Early Neolithic to Late Iron-Age

As the sea pushed inland, it created a complex, fluctuating environment: 

The "Black Fens". Inland, away from direct marine influence, impeded drainage caused rivers to flood, creating vast, stagnant freshwater bogs. Here, thick layers of peat accumulated, trapping ancient forests that had once thrived on the valley floor. These are the "bog oaks" often discovered today—remnants of the forests drowned as the water table rose.

The "Silt Fens".  Closer to the Wash, marine and estuarine clays and silts were deposited during successive tidal advances and retreats.

Human Adaptation. Early prehistoric societies lived on the "islands" of higher Jurassic clay (like Ely) and along the fen edges. By the Bronze Age (notably sites like Flag Fen and Must Farm), communities had mastered the landscape, building sophisticated wooden track-ways and platforms to traverse the marshy, water-logged terrain.

The Roddons. "Stranded Sea Serpents"

One of the most distinct features of the Fenland are the roddons. These are raised, winding banks of silt and sand that stand 2–3 metres above the surrounding peat. They represent the fossilised beds of ancient tidal creeks. As the surrounding peat shrank due to subsequent drainage and oxidation, these silt-filled channels were left standing as positive topographical features, tracing the paths where water once flowed through the marsh.

Benefits of this landscape (Brecks combined with Fen-edge and rivers)

The Breckland Plateau offered light soil that could easily be broken for agriculture. It has been suggested that the sandy soils of Early Neolithic Breckland, would have supported a more open wildwood, a natural woodland pasture for livestock.

It also offered access to incredibly high quality raw material of flint. Not only the hard to obtain floorstone flint. But spread all over the surface of its sandy soils.

The river valleys of the Brecks in turn, offered transport corridors. The prehistoric highways of the British wildwood. Their riparian margins and lower terraces would have offered seasonal alluvial pasture. The westward flowing river valleys of the Brecks, discharged into the ever-changing waterways of the Fens - and onwards to the South and the West. Or northwards to the North Sea and coastal resources.

The Fen-edge offered high-protein hunting and fishing (including eel trapping). And it gave access to building materials of reed and sedge. The edges would have offered rich, seasonal grazing of livestock.

The sands of the Brecks, and the peat of the Fens together, provided an attractive nexus, for trade, and social life. We are aware that on the Fen-Edge itself (and at mere sites in the Brecks), that the open waters and marshes had a ritual, and belief-system value. A meeting of two worlds as epitomised by the Middle Bronze Age Flag Fen site. With such a rich mixture of local resources.

The Thetford Forest Archaeological Project revealed that flint knapping debris, waste cores, and hammer-stones often increase  with frequency on the terraces closest to the rivers.

Origins of the British, Irish, and English

I've modified this from a post that I made on a DNA forum, in response to people discussing out-dated origin stories, in response to a thread looking at ancestral composition for the English.  There is so much misinformation out there, and few people actually try to look at the latest evidences.

It starts by looking at the key points of a recent Irish study.

Cassidy, Martiniano, Murphy etal Study of Neolithic and Bronze Age migration to Ireland

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

https://www.theguardian.com/science/2015/dec/28/origins-of-the-irish-down-to-mass-migration-ancient-dna-confirms

Key points.

  • Ancient DNA from earlier Neolithic farmers suggests an origin from the Near East.

  • Later DNA from Bronze Age suggests a new population had arrived and dominated, with origins from the Eurasian Steppes, including the present day predominance of Y haplogroup R1b, lactose tolerance, and blue eyes. This displacement event appears to have occurred throughout much of Western Europe. The founder population on the Steppes has been linked to the archaeological population known as the Yamna or Yamnaya.

A background to the Yamna hypothesis to help people understand what the above study supported:

The Yamnaya were a population that existed across the Pontic and Caspian Steppes from what is now Ukraine, to Kazakhistan. They themselves were an admixed population, with ancestry from various different groups of Eurasian hunter-gatherers, and from the ANE (Ancient North Eurasian). They carried a number of successful adaptations, including the use of the wheel, improved selective breeding of horses for both riding and haulage, lactose tolerance, use of horse drawn wheeled carts, and a very successful pastoral based economy revolving around the herding of a number of species of livestock.

They are strongly figured to have carried an Indo-European language into Europe and elsewhere (South and Western Asia). That Indo-European language being the ancestor of the vast majority of modern European languages today. They may have also carried many of the most common haplogroups of modern Europeans, including Y hg R1a, R1b, and some mt hg H types among others.

There is a hypothesis that the earlier peoples of Europe, the Early Neolithic farmers, who had largely descended from early farmers in the Levant / Anatolia, had been suppressed by a number of possible environmental and climatic events. This might have paved the way for such a successful displacement of European populations.

As the descendants of the Yamna swept westwards into Europe during the Copper Age, so they spawned a series of new archaeological cultures including the Corded Ware of Eastern and Central Europe, and the Bell Beaker culture of Western Europe.

The Bell Beaker culture spread from Central Europe to the Western Atlantic Seaboard, and from Portugal up to Scotland. Classic artifacts include archer burials in round barrows, the bell beaker ware pottery, round scrapers, and barbed and tanged arrowheads. It was the dominant culture of Early Bronze Age Europe.

One suggestion is that it spawned the later Iron Age Celtic cultures, including the classic Western Atlantic Seaboard Celtic Culture. This culture may have simply evolved locally and through trade links along that seaboard.

The Irish study above supports the Yamnaya hypothesis. It supports displacement during the Early Bronze Age, and that the present day, fairly homogeneous population of Ireland, largely descends from Copper Age Eurasian Steppe pastoralists.

Okay, so what if we apply that also to the late prehistoric British populations? Scottish and West British today appear to have a close genetic distance to the Irish. How about the lowland SE British? It might be the case, that they had fresh admixture, exchanged with the Continent, and particularly with the expanding Germanic cultures. These events could have occurred even during late prehistory.

Now People of the British Isles (POBI) Study 2015:

http://www.peopleofthebritishisles.org/nl6.pdf

This genetic study looked at the British Isles including Northern Ireland, but excluding the Republic of Ireland. It tested a large sample group of present day British with known local ancestry.

Key points.

  • Orkney had the most distinctive population, with a known high percentage of Norse ancestry.

  • The Welsh were distinct from the English. However, they were the most diverse group, with a clear division between the North Welsh and South Welsh. Cornwall was also distinctive from English.

  • Northern Ireland clusters with Scottish.

  • There was no homogeneous shared British “Celtic” population. The Scottish, North Welsh, South Welsh, and Cornish being quite distinct from each other.

  • The South-East British (most of the English) were surprisingly homogeneous, although the boundaries of the old Anglo-Saxon kingdoms could still be distinguished.

  • The Continental Anglo-Saxon contributiion to present day English people appeared to be circa 10% to 40%. This contradicts Bede's claims of a genocide. The English descend more from earlier British populations than they do from Anglo-Saxon immigrants.

  • Although the Norwegian Viking contribution to Orkney was distinctive, the Danish contribution to Eastern England could not be detected. This may be because of the close genetic distance between Danish Viking and some earlier Anglo Saxon settlers makes it impossible to see.

  • Although there was no “Celtic Fringe”, the Welsh appear to be closest to the late prehistoric British population.

  • Any Iberian contribution appears to be tiny and insignificant.

  • There appeared to be a contribution in Southern Britain, particularly in Cornwall, from a population shared today by the North French. This contribution appears to have occurred during late prehistory and is historically unknown.

Okay, so that is suggesting a diversity across the British Isles that extends into Prehistory. A key finding to this thread is that it found the English to be an admixed population, with earlier British ancestry dominating Anglo Saxon ancestry from the Continent.

Finally, I think it is worthwhile bringing up another recent study:

Iron Age and Anglo Saxon Genomes from Eastern England. Schiffels, Haak, etal. 2015.

This qualitative study focused on ancient DNA from a number of Iron Age and Anglo Saxon cemeteries in the Cambridge area of SE England, referenced against modern populations.

Key points.

  • The East English derive 38% of their ancestry from Anglo-Saxon immigrants

  • The closest genetic distances on the Continent between the Anglo Saxon settlers and present day Europeans was to the Dutch and Danish.

  • They found evidence of admixture and intermarrying. Individuals with both Iron Age British, and Anglo Saxon ancestry.

  • People of Iron Age British ancestry were adopting and embracing Anglo-Saxon culture and grave goods.

  • The richest graves were of local Iron Age British ancestry (with Anglo Saxon cultural artifacts). The poorest graves were recent Anglo-Saxon arrivals.

My conclusion:

  • We have to be careful about who we regard as the Celts. A Celtic culture did exist, but it wasn’t necessarily brought to the British Isles and Ireland by an Iron Age people. It may have developed on the Western Atlantic Seaboard from earlier Bronze Age peoples.

  • Those Bronze Age peoples, predominantly descended, from Eurasian Steppe Pastoralists, that had swept across Europe, bringing innovations. They are the oldest peoples of Ireland and the British Isles, but they did not form a homogeneous Celtic Fringe. There must be more to it.

  • The Anglo-Saxon event in SE Britain was a major and significant migration. However, it was not the genocide of Bede's claims. Hengist and Horsa were clearly mythological origin characters akin to Romulus and Remus.

  • The modern day English are an admixed population. They have a foot both in earlier British ancestry, and in Anglo-Saxon / North Sea migration.
