The genome of the offspring of a Neanderthal mother and a Denisovan father.

Abstract

Neandertals and Denisovans are extinct groups of hominins that separated from each other more than 390,000 years ago1,2. Here we present the genome of “Denisova 11”, a bone fragment from Denisova Cave (Russia)3, and show that it comes from an individual who had a Neandertal mother and a Denisovan father. The father, whose genome bears traces of Neandertal ancestry, came from a population related to a later Denisovan found in the cave4–6. The mother came from a population more closely related to Neandertals who lived later in Europe2,7 than to an older Neandertal found in Denisova Cave8, suggesting that migrations of Neandertals between eastern and western Eurasia occurred sometime after ~120,000 years ago. The finding of a first-generation Neandertal-Denisovan offspring among the small number of archaic specimens sequenced to date suggests that mixing between Late Pleistocene hominin groups was common when they met.
