The analysis confirmed previous studies that showed that Modern Humans interbred with Neanderthals and Denisovans.

Most interestingly, the researchers noticed that one percent of the DNA in the Denisovans from an even more ancient human ancestor.

Fifteen percent of the genes that this ancestor passed onto the Denisovans still exist in the Modern Human genome.

The fact that this ancestor separated from the linage that would lead to modern humans about 1,000,000 years ago is the most useful one we currently have.

The bane of all school teachers focusing on human evolution and the original "missing link," Homo Erectus was the first human ancestor to leave Africa.

It should be repeated that while Homo Erectus is the probable source of this ancient DNA, the jury is still out.
