As scientists, researchers and scholars have retraced the evolution of mankind over the centuries, there have been two other humanoid species that mankind has been found to be most closely related to: Neanderthal and Denisovan.
Now, evidence has surfaced that the island people of Melanesia might just have DNA reflecting involvement of a third species that the world has never seen before. Currently, researchers think that this mystery DNA originated in the South Pacific, just northeast of Australia.
One scientist by the name of Bohlender has studied DNA and its historical ties for years, and he tells us that we have yet to piece together all of ancient human history. While he agrees that humans are closely related to both Neanderthals and Denisovans, he also believes that there is a third species that represents a small portion of the human population today.
One study conducted earlier this year discovered links between Neanderthal DNA and certain conditions, like depression, cardiovascular disease and others. It also found that HPV was likely transmitted between Neanderthals and Denisovans.
Because of these finds, Bohlender believes that the true history of Neanderthals is most likely quite different than the history widely believed today. He’s confident that there are things that happened along the Neanderthal’s species timeline that we are not aware of; we’re missing a part of the picture.
His theory is that this third species is one of the missing links to explaining why these specific tribespeople in Melanesia possess DNA that is currently not seen anywhere else in the world. Of course, this is just a theory at the moment, as there is no concrete evidence suggesting a third human-like species existed.
Thus far, they have only found a few bones and teeth that could be tied to a potential missing link, so until a huge discovery is made, this unknown human DNA will remain a mystery.
