Neanderthal Fossil
Last 2010, scientists and researchers tried to figure out the order of DNA nucleotides or bases of a Neanderthal fossil, which they found from Croatia. Upon finishing the sequencing, it was found out and had become clear that the Neanderthal indeed tried mating with modern humans. Researchers believed that the first contact might have taken place about 60,000 years ago when they were still in the Middle East. Today, it is believed that all humans, except for the Africans, were up to a certain percentage of the Neanderthal DNA.
The Denisovans
The same happened in Asia. It is believed that human species also mated with the Denisovans – a similar group of hominin species that stayed in Asia. We couldn’t say much about them because there were only a few studies about Denisovans. Historical discoveries about them were not that much. Even the DNA that lay in them was only a few. That DNA is reflected by only up to 4 percent of the genes in some modern first Australian peoples and the other related Melanesian peoples – the inhabitants of the Melanesian area.
