New ancestor to humans discovered

Andaman Islanders have DNA fragments of a third ancestral line.

Scientists at the Institute of Evolutionary Biology (IBE) ... have discovered a new type of now extinct hominid that lived in south-east Asia. This species, not described to date, is an ancestor of humans like the Neanderthals and the Denisovans and they crossed with modern humans tens of thousands of years ago.

The genetic analysis of a group of individuals from the Andaman Islands in the Indian Ocean has revealed that their DNA contains fragments that do not correspond to modern humans who left Africa about 80,000 years ago. When comparing these sequences with those of Neanderthals and Denisovans, scientists have seen that they also are clearly different. The researchers of the IBE have concluded that this DNA belongs to an extinct hominid that shares a common ancestor with the other two but has a different history.

Soon, perhaps, a DNA fragment unrelated to earth bound species will be postulated. 

First, Ruth, I like your new Avatar, as I have enjoyed the others. You look especially gentle in this one coupled with a curious eye. 

Now, to the common ancestor of chimpanzees, as well as African, European, East Asian, and the Asia & Pacific humans. Even the now extinct Neanderthal, Denisova, and the unknown southeast Asian group. 

The "so-called Out of Africa, from which all modern humans are descended, came about in a single migration.
