In Photos: A Bone from a Denisovan-Neanderthal Hybrid

A huge discovery

This bone fragment, called "Denisova 11," was found in 2012 at Denisova Cave in Russia by archaeologists. New DNA evidence reveals the bone originally came from a girl or woman who was the daughter of a Neandertal mother and a Denisovan father.

Hidden treasures

The valley in Siberia where the Denisova Cave archaeological site sits. It has yielded many new insights into some of our extinct, ancient human relatives.

Layers of history

This stratigraphic profile of the East Chamber in Denisova Cave can reveal the ages of different archaeological finds.

Researchers unearth the past

Richard (Bert) Roberts, Vladimir Ulianov and Maxim Kozlikin (clockwise from top) excavate in the East Chamber of Denisova Cave. The cave was already known to contain Neanderthal and Denisovan bones, though not necessarily from the same period.

Clean room

Here, the clean laboratory at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, where the ancient DNA was analyzed. Researchers must be meticulous to avoid contaminating ancient DNA samples.
