Ancient teeth hint at canoodling between early human relatives - ABC News - Breaking News, Latest News and Videos
Overview
An analysis of ancient teeth gives researchers a rare physical glimpse into close interactions between different early human relatives hundreds of thousands of years ago. The dental evidence, which suggests intimate contact and gene flow among groups, complements more recent archaeological work such as the Nile Delta cemetery excavation in Egypt, where burial remains reveal changing social practices over centuries. Together these lines of evidence help link individual biological interactions to broader cultural and population changes through time.
