A new study in Nature examines over 2,000 years of population history in Argentina's Uspallata Valley, showing local hunter-gatherers adopted farming rather than it being introduced by migrants. Later, maize-dependent groups from nearby areas migrated into the region amid climate instability, disease, and population decline. Kinship networks helped communities endure without evidence of violence.

A new computational analysis of Paleolithic artifacts reveals that humans over 40,000 years ago engraved structured symbols on tools and figurines, indicating early forms of information recording. These signs, found mainly in southwestern Germany, show complexity comparable to the earliest known writing systems that emerged millennia later. Researchers suggest these markings were purposeful, predating formal writing by tens of thousands of years.

A 2.6-million-year-old jawbone discovered in Ethiopia's Afar region marks the first known fossil of the robust hominin Paranthropus from that area. Found about 1,000 kilometers north of previous sites, the specimen suggests this early human relative was more adaptable and widespread than previously thought. Led by University of Chicago paleoanthropologist Zeresenay Alemseged, the discovery challenges long-held views on hominin competition and evolution.

A new study challenges the view of scavenging as a primitive fallback for early humans, portraying it instead as a smart, reliable survival strategy that shaped our evolution. Led by Spain's CENIEH, the research emphasizes how carrion consumption provided essential nutrition with less effort than hunting. Human traits like strong stomach acid and long-distance mobility made scavenging particularly effective.
