That’s according to a new study conducted by an international team of academics that included Southern Methodist University archaeologist David Meltzer. The team was led by the University of Cambridge in the United Kingdom, and the University of Copenhagen in Denmark.
Meltzer’s expertise includes the First People in the Americas, according to SMU. He is Henderson-Morrison Professor of Prehistory in SMU’s Department of Anthropology in Dedman College.
The study sequenced the genomes of individuals found at an ancient burial site in Russia.
The team discovered that individuals were, at most, first cousins, which showed that they had developed sexual partnerships beyond their immediate social and family group, SMU said.
Ancient genomics shed light on aspects of social life among early humans, and the results pave the way for further studies to explore variation in social and demographic strategies in prehistoric societies, according to SMU.
“This study takes us a step further toward pinpointing when and why the things that make humans unique evolved,” Robert Foley, a professor at the University of Cambridge, said.
