Using cobraa, we present evidence for an extended period of structure in the history of all modern humans, in which two ancestral populations that diverged ~1.5 million years ago came together in an admixture event ~300 thousand years ago, in a ratio of ~80:20%. Immediately after their...

• A 7000-year-old genome from the Caucasus links the Volga’s first herders to farmers of W. Asia • Human DNA points the spread of farming through the Caucasus to the Eastern European steppes...

Skeletal remains of a group of foragers massacred around 10,000 years ago on the shores of a lagoon is unique evidence of a violent encounter between clashing groups of ancient hunter-gatherers, and suggests the “presence of warfare” in late Stone Age foraging societies...

Gene flow from Neandertals has shaped the landscape of genetic and phenotypic variation in modern humans. We identify the location and size of introgressed Neandertal ancestry segments in more than 300 genomes spanning the last 50,000 years. We study how Neandertal ancestry is shared among...

it's a preprint and it claims a Eureopean origin for Proto-Indo-Anatolian, contrary to an earlier study that claims a western Iranian or Transcaucasian origin for Indo-Europeans : The Yamnaya archaeological complex appeared around 3300BCE across the steppes north of the Black and Caspian Seas...

It's a bias problem physicists seem to be aware of, but not the IPCC?

https://www.nature.com/articles/s41586-023-06865-0#additional-information The broad lines are already known for a decade, but the resolution becomes higher and higher. It is also becoming increasingly difficult to absorb the vast amount of information.

In remote Siberia, hunter-gatherers built complex defenses 8000 years ago. We can now see there are many societies in the archaeological record who are hunter-gatherers but have many of the features we traditionally assumed were associated with farmers...

Today, there are more than 8 billion human beings on the planet. We dominate Earth’s landscapes, and our activities are driving large numbers of other species to extinction. Had a researcher looked at the world sometime between 800,000 and 900,000 years ago, however, the picture would have been...

In northwestern Africa, lifestyle transitioned from foraging to food production around 7,400 years ago but what sparked that change remains unclear. Archaeological data support conflicting views: (1) that migrant European Neolithic farmers brought the new way of life to North Africa1–3 or (2)...

Despite the localisation of the southern Caucasus at the outskirt of the Fertile Crescent, the Neolithisation process started there only at the beginning of the sixth millennium with the Shomutepe-Shulaveri culture of yet unclear origins. We present here genomic data for three new individuals...

?British-Irish ancestry has an impact on Scandinavia from the Viking period onward ?Eastern Baltic ancestry is more localized to Gotland and central Sweden ?Modern Scandinavians have less non-local ancestry than Viking Age samples ?The north-south genetic cline is mainly due to differential...

AbstractThe human microbiome has recently become a valuable source of information about host life and health. To date little is known about how it may have evolved during key phases along our history, such as the Neolithic transition towards agriculture. Here, we shed light on the evolution...
