Rethinking the earliest stages of cereal domestication

A new integrated isotope study reveals that environmental conditions, rather than human selection, drove the initial increase in cereal grain size in southwest Asia around 11,000 years ago. The research found that larger grains grew under wetter conditions, while smaller wild-sized grains grew under drier conditions.

Family relationships identified in Stone Age graves on Gotland

In a new study, researchers at Uppsala University clarified family relationships in four graves from a 5,500-year-old hunter-gatherer culture at Ajvide on Gotland. DNA analyses suggest that the people were well aware of family lineages and that relationships beyond the immediate family played an important role. The analysis showed that...

From ochre to innovation

A new study reveals that early modern humans at Blombos Cave in South Africa used ochre as a multi-use tool for stone toolmaking, showcasing advanced technical skills. The discovery challenges traditional interpretations of ochre and highlights its integral role within technological systems.

Cleveland Museum of Natural History researchers propose new hypothesis for the origin of stone tools

Researchers at Cleveland Museum of Natural History propose that early humans used naturally sharp rocks as cutting tools before developing their own stone technology. This new hypothesis challenges current understanding of the origin of stone knapping, suggesting a more extensive use of natural resources than previously thought.

South African rock art possibly inspired by long-extinct species

A study published in PLOS ONE suggests that South African rock art from the 19th century may be inspired by an extinct species of tusked animal called a dicynodont. The artwork, created by the San people, features a long-bodied animal with downward-turned tusks that is comparable to fossilized remains found in the region.

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.

Research reveals longstanding cultural continuity at oldest occupied site in West Africa

A study from the Max Planck Institute of Geoanthropology found technological continuity spanning 140,000 years at Bargny 1 site in Senegal, suggesting Middle Stone Age toolkits persisted longer than thought. The research highlights long-term cultural stability in West Africa's diverse habitats.

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.

Friendship ornaments from the Stone Age

A study by University of Helsinki researchers suggests that some Stone Age ornaments were deliberately fragmented as part of social relations, bartering, or ritual activities. The analysis of geochemical composition and use traces revealed fragments from the same ornament found in different locations, indicating they were worn by two i...

In Guatemala, archaeologist from Brown helps to uncover hidden neighborhood in ancient Maya city

A recent discovery at Tikal reveals a previously unknown neighborhood designed to replicate Teotihuacan's citadel, sparking new insights into the interaction between the two civilizations. Excavations found evidence of occupation and surveillance, as well as artifacts linking Tikal to Teotihuacan's imperial power.

DNA increases our understanding of contact between Stone Age cultures

Researchers analyzed DNA from 25 Stone Age individuals and found that those buried in typical Pitted Ware culture graves were genetically similar to earlier Scandinavian hunter-gatherers. The presence of Battle Axe culture influences in some graves suggested trade and cultural exchange between the groups, rather than genetic migration.

Stone-Age social networks

A study of ostrich eggshell bead exchange reveals that relationships among hunter-gatherer groups existed across hundreds of kilometers in late Middle Stone Age southern Africa. The size of the network provided access to high ecological diversity and offered a social strategy against scarcity.

Archeological discovery yields clues to how our ancestors may have adapted to their environment

Researchers discovered bone and tooth specimens of wild camels, elephants, horses, and antelopes at Azraq Basin site, providing insights into ancestral human adaptation to changing environments. The team found evidence of butchery and suggests that humans may have faced challenges from predatory competitors like lions and hyenas.

Underwater Stone Age settlement mapped out

Researchers at Lund University have mapped out an exceptionally well-preserved Stone Age site in southern Sweden, shedding light on the lives of Mesolithic humans. The discovery includes a 9,000-year-old pick axe made from elk antlers, indicating mass fishing and a semi-permanent settlement.
