Ancient cooking pots reveal gradual transition to agriculture

Researchers analyzed ancient pottery for signs of terrestrial, marine, and freshwater organisms, finding that fish and aquatic resources continued to be exploited after the advent of farming. This suggests a gradual transition from hunting to agriculture in Western Europe, challenging previous assumptions about the abrupt shift.

Apple iPhone 17 Pro delivers top performance and advanced cameras for field documentation, data collection, and secure research communications.

Northern hunters slowed down advance of Neolithic farmers

Researchers have proposed a new model to explain how the Neolithic front slowed down as it moved towards northern Europe. The study suggests that the farmers' dispersal and reproduction were limited by the high density of hunter-gatherers in the region.

Stone Age Scandinavians unable to digest milk

A new study by researchers at Uppsala University and Stockholm University found that Stone Age Scandinavians were lactose intolerant. This discovery challenges earlier conclusions about the ancestry of modern Swedes.

I think step to the left, you think step to the east

A study reveals cultural variations in spatial relationships, with nomadic hunter-gatherers remembering body movements differently than Westerners. German children followed a consistent pattern, while Hai||om children adapted their movements based on direction.

Scandinavians are descended from Stone Age immigrants

A new study suggests Scandinavians are not direct descendants of hunter-gatherers who lived in the region during the Stone Age. The research uses DNA from ancient remains to investigate the spread of agriculture and livestock practices.

Europe's first farmers replaced their Stone Age hunter-gatherer forerunners

New research suggests that Europe's first farmers migrated into central and Eastern Europe around 7,500 years ago, bringing domesticated plants and animals with them. The study analyzed DNA from hunter-gatherer and early farmer burials, finding little evidence of a direct genetic link between the two groups.

Meat for sex in wild chimpanzees

Researchers found that male chimpanzees who share their food with females can mate more often than those who don't. Sharing meat over long periods of time doubles a male's mating success, while females increase their caloric intake without incurring energetic costs.

Wild chimpanzees exchange meat for sex

Researchers found that females copulate more frequently with males who share meat with them, compared to those who never share. This suggests that sharing meat with females improves males' mating success and may be a long-term strategy for securing mates.

ASU genetics research sheds light on evolution of the human diet

Researchers at ASU have discovered that humans have a unique genetic adaptation to starch consumption, with high-starch diets associated with more copies of the AMY1 gene. This finding provides insight into why certain populations may be better equipped to handle diarrheal diseases.

Girls prefer pink, or at least a redder shade of blue

Researchers discovered a clear preference for pink or reddish hues among women, shifting their color preference towards red and away from blue. The study suggests that this difference may be driven by biological factors, potentially related to evolution and the importance of ripe fruit in hunter-gatherer societies.

An evolutionary road less traveled

Researchers found that genetic diversity of the Mlabri is significantly lower than other agriculture-based hill tribes, indicating a severe population reduction around 500-1000 years ago. This reverts previous assumptions that contemporary hunter-gatherer groups represent pre-agricultural human populations.
