Offspring of Neanderthal and Denisovan identified for first time

Discovery suggests that distinct ancient human species may have mingled and interbred happily

A small piece of bone found in a cave in Siberia has been identified as the remnant of a child whose mother was a Neanderthal and father was a Denisovan, a mysterious human ancestor that lived in the region.

Researchers made the discovery when they examined DNA extracted from the bone and found that it contained chromosomes from a Neanderthal female and a Denisovan male. It is the first time that the offspring of such a coupling has been identified.
