Editor's picks

Illustration of a teenage girl who is the offspring of a Neanderthal (Homo neanderthalensis) mother and Denisovan (Homo sapiens denisova) father. A bone fragment with this hybrid ancestry was found in the Denisova Cave in Russia. The bone belonged to a female who was at least 13 years old and died around 90,000 years ago. It was known from genetic analysis of other fossils that the two species had interbred, but this is the first first-generation offspring of such a pairing to be found.
