Spotting ancient sites, from space

A Harvard archaeologist developed a system to identify early human settlements based on satellite image analysis, uncovering approximately 9,000 possible sites in northeastern Syria. This technique simplifies the process of finding ancient settlements, allowing for more efficient and targeted surveys.

Fish on the menu of our ancestors

A study of a 40,000-year-old human skeleton found high levels of nitrogen isotopes suggesting regular consumption of freshwater fish. This suggests that early modern humans in China had access to fish as a food source before the development of effective fishing gear.

Which way 'out of Africa'?

Researchers find fossil river channels in Libya with a distinctly volcanic signature, supporting the theory that monsoon rains fueled rivers to the Mediterranean. The discovery provides an alternative route for early human migrations out of sub-Saharan Africa.

Dawn of human matrilineal diversity

A team of researchers analyzed 600 complete mtDNA genomes from indigenous populations across Africa to discover the early demographic history of human populations before they moved out of Africa. The study reveals that these early human populations were small and isolated for tens of thousands of years.

Stone tools reveal ancient seafood diet

A new study of ancient stone tools in Eritrea reveals that early humans harvested seafood in Africa around 125,000 years ago. The discovery suggests a widespread adaptive strategy in early human behavior that spread across the continent between 115,000 and 125,000 years ago.
