Highlights
An ancient child from Siberia is believed to be the only know individual whose parents were from two different species. The studied remains belonged to a girl who had a Neanderthal mother and a Denisovan father.
The ancient teenager
Found in Denisova Cave, this child — known as “Denisova 11” — was at least 13 years of age at the time of her death. Analysis of a piece of her bone found that the girl died more than 50,000 years ago. The cause of her death and how she lived is still being investigated.
This discovery occurred through ancient DNA analysis, whereby a small piece of the teenager’s bone was pulverised, the DNA extracted, and then sequenced. The sequence was then compared to previously analysed samples from Neanderthals, modern humans, and Denisovans. Her genetic traits could only be explained if her mother was a Neanderthal and her father was a Denisovan.
Species replaced by humans 40,000 years ago
Neanderthals and Denisovans inhabited Eurasia until about 40,000 years ago when they were replaced by modern humans (Homo sapiens). But before this replacement occurred, there appears to have been a fair bit of mingling going on whenever the different groups met.
