Our closest evolutionary relatives, the Neanderthals (Homo neanderthalensis), were once spread across Europe and as far east as the Altai Mountains in southern Siberia.

Our closest evolutionary relatives, the Neanderthals , were once spread across Europe and as far east as the Altai Mountains in southern Siberia.

Our new study is the first to analyse ancient DNA from the teeth and bones of multiple Neanderthals who lived at around the same time. The fossils came from archaeological excavations of Okladnikov Cave in the mid-1980s and Chagyrskaya Cave since 2007. The teeth and bones came from 13 individuals: 11 from Chagyrskaya Cave and two from Okladnikov Cave. Seven of the Neanderthals were male and six were female. Eight were adults and five were children or adolescents.

Taken together with the evidence for their close family connections, these indicate the Chagyrskaya Neanderthals must have lived – and died – at around the same time.Our analyses also revealed this Neanderthal community had extremely low genetic diversity – consistent with a group size of just 10 to 20 people.
