He explained that if humans were descended without any back-crossing we would be about halfway, genetically speaking, between chimpanzees and whatever organism was the other parent. One can suppose that humans are back-cross hybrids because humans are highly similar to chimpanzees at the genetic level, closer than they are to any other animal, McCarthy said. ![]() McCarthy said that in the case of chimp - pig hybridisation, the "direction of the cross" would likely have been a male boar or pig (Sus scrofa) with a female chimp (Pan troglodytes), and the offspring would have been nurtured by a chimp mother among chimpanzees, '' reported. In an article on his website, McCarthy wrote that humans are the result of multiple generations of back-crossing to the chimpanzee. The bizarre theory has been proposed by Eugene McCarthy, of the University of Georgia. ![]() Darwin must be turning in his grave! Humans may actually be the hybrid offspring of a male pig and a female chimpanzee, a US geneticist has claimed.
