In the Neolithic, agriculture took root gradually

The study reveals that genetic mixing with hunter-gatherers increased locally over time during the Neolithic expansion, leading to a complex colonization process. Early farmers had a demographic advantage, with an effective population size five times larger than hunters.

When ideas travel further than people

A new study reconciles opposing views on the spread of Neolithic farming by combining archaeology and genetics. The research found that cultural changes occurred through both people migration and the spread of ideas, depending on the region and period.

Ancient DNA analyses imply brucellosis evolved with development of farming

Researchers analyzed ancient DNA from an 8,000-year-old sheep bone and found evidence of Brucella melitensis, a pathogen causing significant harm to livestock. The study suggests that brucellosis evolved around the same time as farming development, with early farmers creating conditions for pathogen host-jumping.

Stone Age strategy for avoiding inbreeding

A new study from Uppsala University found that Stone Age hunter-gatherer communities in Western Europe deliberately formed distinct families to avoid inbreeding and maintain genetic diversity. The research analyzed the genomes of several individuals buried at iconic sites in France, dating back to around 6,700 years ago.

Ancient genomes reveal immunity adaptation in early farmers

Researchers found that a large genetic region responsible for immune responses showed rapid evolution and more Mesolithic hunter-gatherer ancestry, suggesting that genetic variants already present in Europe were passed down preferentially. This suggests that diversity in immune genes may be just as important as adaptation to lifestyle.

Violence was widespread in early farming society, study says

New research suggests that violence and warfare were prevalent in many Neolithic communities across Northwest Europe during the period of farming adoption. Over 10% of skeletal remains from 180 sites dating back to 8000-4000 years ago showed evidence of weapon injuries, including blunt force trauma and penetrative injuries.
