Our ancestors were in physical contact with another species of human as recently as 25,000 to 30,000 years ago, a study of lice reveals.
Researchers found that people todayattract two genectically distinct types of head lice. One is found worldwide and evolved on the ancestors of our species, Homo Sapiens.
The other, found only in the Americas evolved on another early human species. Prof. Dale Clayton, who led the US study said: 'Kids today have lice that evolved on two species of cavemen. One led to us, the other became extinct.'
