The proximity of these remains to colossal-megalithic structures further fuels the debate that genetically modern humans once coexisted with a giant hominid species. Plus, high levels of Denisovan DNA are being reported throughout the world's populations. Thus, we are beginning to see that the story of human evolution is far more complicated that we could have ever imagined.
