Hunter-gatherers got on fine with Europe’s first farmers
We know that our species originated in Africa and likely reached Europe from the southeast no later than 42, years ago. During the last ice age some 33,, years ago, when a permanent ice sheet covered northern and parts of central Europe, modern humans in southwest Europe were isolated from groups further to the east. When the ice sheet retreated, some of these hunter gatherers eventually colonised Scandinavia from the south about 11, years ago, making it one of the last areas of Europe to be inhabited.
But exactly who these individuals were and how they got there has remained a puzzle for researchers. Now we have sequenced the genomes of seven hunter gatherers, dated to be 9,, years old, to find out.
After the first farmers colonised Europe, local hunter-gatherers hung around for two lived alongside each other for millennia and even shared burial sites. are 10, to 11, years old – and so date from before European farming. into central Europe, first from the east and then from the south-west.
The term is often abbreviated as WHG. Among modern-day populations, WHG ancestry is most common among populations of the eastern Baltic. Western Hunter-Gatherers WHG were identified as a distinct ancestral component in a study published in Nature in They were found to have contributed ancestry to all modern Europeans , including Early European Farmers EEF , who were however mostly of Anatolian descent.
Southern areas of the eastern Baltic were found to be more closely related to WHG than northern and eastern areas. Modern populations of the eastern Baltic thus harbors a larger amount of WHG ancestry than any other population in Europe. A study published in Nature in February included an analysis of a large number of individuals of prehistoric Europe. Of the nine samples of Y-DNA extracted, six belonged to I haplotypes particularly subclades of I2a , one belonged to C1a2 , one belonged to R , and one possibly belonged to J.
Of the eleven samples of mtDNA extracted, nine belonged to U51b haplotypes, one belonged to U5a2c , and one belonged to an U2 haplotype. These results suggested that WHGs were once widely distributed from the Atlantic coast in the West, to Sicily in the South, to the Balkans in the Southeast, for more than six thousand years.
Samples of Y-DNA extracted from these individuals belonged exclusively to R haplotypes particularly subclades of R1b1 and I haplotypes particularly subclades of I2. The males at these sites carried exclusively haplogroup R1b1a and I mostly subclades of I2a haplotypes.
A New Origin Story for Dogs
The Neolithic lifestyle, including farming, animal domestication and the development of new technologies, emerged in the Near East around 12, years ago and contributed profoundly to the modern way of life. The Neolithic spread rapidly across Europe, mainly along the Danube valley and the Mediterranean coastline, reaching the Atlantic coast around BCE. The existing archaeogenetic data from prehistoric European farmers indicates that the spread of farming is due to expanding populations of early farmers who mixed little, if at all, with indigenous hunter-gatherer groups.

Scotland) to By contrast, all directly dated individuals who post-date ments cluster tightly near Iberian and Central European Middle British Mesolithic individuals with various European hunter-gatherer Phy-Mer: a novel alignment-free and reference-.
However, the routes and genetic composition of these postglacial migrants remain unclear. Surprisingly, among the Scandinavian Mesolithic individuals, the genetic data display an east—west genetic gradient that opposes the pattern seen in other parts of Mesolithic Europe. Our results suggest two different early postglacial migrations into Scandinavia: initially from the south, and later, from the northeast.
The latter followed the ice-free Norwegian north Atlantic coast, along which novel and advanced pressure-blade stone-tool techniques may have spread. These two groups met and mixed in Scandinavia, creating a genetically diverse population, which shows patterns of genetic adaptation to high latitude environments. These potential adaptations include high frequencies of low pigmentation variants and a gene region associated with physical performance, which shows strong continuity into modern-day northern Europeans.
The Scandinavian peninsula was the last part of Europe to be colonized after the Last Glacial Maximum. The migration routes, cultural networks, and the genetic makeup of the first Scandinavians remain elusive and several hypotheses exist based on archaeology, climate modeling, and genetics.

‘Cheddar Man,’ Britain’s Oldest Skeleton, Had Dark Skin, DNA Shows
He lived about 10, years ago in the Mesolithic period, the middle part of the Stone Age. Scientists have now reconstructed his features, demonstrating that he was part of a population of ancient Western Europeans that, scientists have shown in recent years, had dark skin. Research has shown that fair skin pigmentation — long considered a defining feature of Europe — only goes back less than 6, years.

Tens of thousands of years ago, before the internet, before the Industrial Revolution, before literature and mathematics, bronze and iron, before the advent of agriculture, early humans formed an unlikely partnership with another animal—the grey wolf. The fates of our two species became braided together. The wolves changed in body and temperament. Their skulls, teeth, and paws shrank.
Their ears flopped. They gained a docile disposition, becoming both less frightening and less fearful.
Use of domesticated pigs by Mesolithic hunter-gatherers in northwestern Europe.
DNA taken from the wisdom tooth of a European hunter-gatherer has given scientists an unprecedented glimpse of modern humans before the rise of farming. The Mesolithic man, who lived in Spain around 7, years ago, had an unusual mix of blue eyes, black or brown hair, and dark skin, according to analyses of his genetic make-up. He was probably lactose intolerant and had more difficulty digesting starchy foods than the farmers who transformed diets and lifestyles when they took up tools in the first agricultural revolution.
The invention of farming brought humans and animals into much closer contact, and humans likely evolved more robust immune systems to fend off infections that the animals passed on.
Central to this discussion is the diet composition and nutrition of contemporary hunters and gatherers, who are frequently conscripted as model.
The spread of domesticated plants and animals throughout Europe between and cal BC involved a complex social and economic interplay between indigenous Mesolithic hunter-gatherers and incoming Neolithic farmers. Although contacts between these two groups were a feature of the social landscape 1 , 2 , 3 , the conduits through which the exchange and transfer of particular technological, subsistence and social elements might have occurred, and the scale of interaction remain hotly debated.
In northern Europe, a number of claims have been made regarding the possibility that some hunter-gatherers had access to domestic animals 5 , 6. Of the dozen or so previous assertions made for the presence of domestic sheep, goat, cattle or pig in Mesolithic contexts from Denmark, northern Germany, Poland and the Netherlands, almost all fail scrutiny in terms of their postulated early dates or their identification as domestic animals 5 , 6 Supplementary Table S1.
Although these remains have been interpreted as the likely importation of joints of meat rather than live cattle 8 , they clearly indicate late Irish Mesolithic links with continental European farmers at a time when no other evidence for such a connection exists in the archaeological record for Britain 9. There remains as yet, however, no convincing evidence in continental northern Europe that late Mesolithic hunter-gatherers had access to domestic animals other than dogs 5.
In the archaeological record of northern Europe, a long period of coexistence circa — cal BC has been documented between late Mesolithic groups and fully agricultural early Neolithic communities 1 , 2 , 3. In contrast, the contemporary Neolithic farming economy was characterized by intensive exploitation of domestic plants and animals such as sheep, goat, cattle and pigs 4 , 19 , 20 , Although early Neolithic LBK domestic sheep and goats clearly originated from the Near East—as no wild progenitors of these species existed in Europe 21 —it is possible that domestic cattle and pigs may have had a local origin because of the Pan-Eurasian distribution of wild aurochsen and boar.

Prehistoric Hunters—Gatherers: The Emergence of Cultural Complexity focuses on the emergence of cultural complexity among hunter—gatherers. This book presents the demographic, ecological, and social perspectives that add to the understanding of the emergence of more elaborate organization. Organized into four parts encompassing 17 chapters, this book begins with an overview of previous perspectives on cultural complexity and suggests directions in the study of change.
This text then proposes a synthesis of both ecological and social approaches as a more powerful interpretative framework for the study of complexity. Other chapters consider the relationship between population and social complexity in an elaboration of major argument regarding demographic pressure and cultural change. This book provides as well an intriguing look at the regional consequences of their focus on whaling.

All rights reserved. Three waves of immigrants settled prehistoric Europe. It has long nourished white racism, and in recent years it has stoked fears about the impact of immigrants: fears that have threatened to rip apart the European Union and roiled politics in the United States. Now scientists are delivering new answers to the question of who Europeans really are and where they came from. Their findings suggest that the continent has been a melting pot since the Ice Age.
Europeans living today, in whatever country, are a varying mix of ancient bloodlines hailing from Africa, the Middle East, and the Russian steppe. The evidence comes from archaeological artifacts, from the analysis of ancient teeth and bones, and from linguistics. But above all it comes from the new field of paleogenetics. During the past decade it has become possible to sequence the entire genome of humans who lived tens of millennia ago.
The result has been an explosion of new information that is transforming archaeology.

In conjunction with this discordance between our ancient, genetically determined biology and the nutritional, cultural, and activity patterns of contemporary Western populations, many of the so-called diseases of civilization have emerged. In particular, food staples and food-processing procedures introduced during the Neolithic and Industrial Periods have fundamentally altered 7 crucial nutritional characteristics of ancestral hominin diets: 1 glycemic load, 2 fatty acid composition, 3 macronutrient composition, 4 micronutrient density, 5 acid-base balance, 6 sodium-potassium ratio, and 7 fiber content.
The evolutionary collision of our ancient genome with the nutritional qualities of recently introduced foods may underlie many of the chronic diseases of Western civilization. Genetic traits may be positively or negatively selected relative to their concordance or discordance with environmental selective pressures 1. When the environment remains relatively constant, stabilizing selection tends to maintain genetic traits that represent the optimal average for a population 2.
