[QUOTE]Originally posted by DD'eDeN: [QB] Our Ancestors Were Breeding With At Least Four, But Potentially More Species Of Other Hominins http://www.iflscience.com/editors-blog/our-ancestors-were-breeding-with-at-least-four-but-potentially-more-species-of-other-hominins/ " But that wasn't the only cross-species sex our ancestors got up to. Known only from a few fragments of bones, the enigmatic Denisovans evolved from the same branch that gave rise to the Neanderthals, and are thought to contribute to between 3 and 5 percent of the genomes of aboriginal Australians. That is literally all we know about the Denisovans. But even more mysteriously, it seems that there is genetic evidence for another species that may have lived in Southeast Asia around the same time as the Denisovans and us. While no physical fossils have ever been found, genetic analysis of Pacific Islanders seems to show that a distinct species of ancient human, thought to be another sister group to the Neanderthals and Denisovans, may have been breeding with our ancestors as they moved into Southeast Asia. Who these may have been, nobody knows. Some suggest that the environment in this part of the world means that fossils are unlikely to survive, while others argue that as we know so little about the genetic diversity of the Denisovans, this mysterious DNA could still be from them. Yet this is not the first time that researchers have discovered what they think is evidence for an ancient species of human hidden in our genes. Analysis of people's genetics in Africa show that something similar may have occurred there too, with suggestions of another cross-species romance. But there is still a hole in African genetics. "Africans have been underrepresented in genetics research - they're not as well studied as European and Asian populations, yet they are more diverse genetically than any other group," Dr Bohlender said. With the rich evolutionary history of hominins within Africa, this will likely yield even more interbreeding events, and it is highly likely there are other yet to be revealed instances from other parts of the planet. As ever, things are never quite as straightforward as they first seem." [/QB][/QUOTE]
