It makes sense I would have a few percent Homo Erectus DNA, I always felt like I had to work harder than my graduate school peers. (j/k)
Some Humans Are Carrying DNA From an Unknown Ancient Ancestor
A new analysis of the genomes of the most famous of ancient humans - Neanderthals and Denisovans - has revealed an as-yet-unidentified ancestor for our species – a branch of our distant family tree without any known label to put to it.
The study also finds further evidence of interbreeding between humans and Neanderthals, but places it much earlier than we previously knew - some 200,000 to 300,000 years ago. This interbreeding would therefore add new insight into the increasingly complicated history of our emergence as a species, and of our migration out of Africa.
There is the possibility that the unknown ancestor is actually Homo erectus, an archaic human ancestor thought to have died out more than 100,000 years ago – but as no H. erectus DNA has ever been found, we don't know for sure.
