Bronze Age European warriors
University of Leicester researchers discover a European male-specific population explosion that occurred between 2000 and 4000 years ago
- Researchers determined DNA sequences from the Y chromosomes of 334 men belonging to 17 populations from Europe and the Middle East
- Study shows that almost two out of three (64%) modern European men belong to just three young paternal lineage
- Male-specific population expansion was widespread, and surprisingly recent, focusing interest on the Bronze Age
Geneticists from the University of Leicester have discovered that most European men descend from just a handful of Bronze Age forefathers, due to a ‘population explosion’ several thousand years ago.

Archaeological evidence and linguistic evidence converge in support of an origin of Indo-European languages on the Pontic-Caspian steppes around 4,000 years BCE. The evidence is so strong that arguments in support of other hypotheses should be reexamined.

This map shows the location of the Upward Sun River site in Alaska where the remains of two infants were found in an 11,500-year-old burial. A new University of Utah analysis shows the infants belong to two genetic groups or lineages known as B2 and C1. The maps shows other Native American groups throughout the Americas that are part of the same lineages.
University of Utah scientists deciphered maternal genetic material from two babies buried together at an Alaskan campsite 11,500 years ago. They found the infants had different mothers and were the northernmost known kin to two lineages of Native Americans found farther south throughout North and South America.
By showing that both genetic lineages lived so far north so long ago, the study supports the “Beringian standstill model.” It says that Native Americans descended from people who migrated from Asia to Beringia – the vast Bering land bridge that once linked Siberia and Alaska – and then spent up to 10,000 years in Beringia before moving rapidly into the Americas beginning at least 15,000 years ago.
“These infants are the earliest human remains in northern North America, and they carry distinctly Native American lineages,” says University of Utah anthropology professor Dennis O’Rourke, senior author of the paper set for online publication the week of Oct. 26 in the journal Proceedings of the National Academy of Sciences.

We estimate mixture proportions using a method that gives unbiased estimates even without an accurate model for the relationships between the test populations and the outgroup populations (Supplementary Information section 9). Population samples are grouped according to chronology (ancient) and Yamnaya ancestry (present-day humans).

In some cases, small bands of potentially as few as 20 to 30 people could have been moving over very large areas, over the whole of Europe as a single territory, according to Professor Ron Pinhasi, principal investigator on the EU-funded ADNABIOARC project.
This demographic model is based on new evidence that suggests populations were much smaller than is generally thought to be a stable size for healthy reproduction, usually around 500 people. Such small groupings may have led to reduced fitness and even extinctions.
‘As an archaeologist and anthropologist, I was quite shocked to see how limited, how small the population numbers were. You know, shockingly small,’ said Prof. Pinhasi, based at University College Dublin, Ireland.
‘I think that what happened, it’s on a catastrophic level of demography for a long time in human evolution,’ he said.
