Ryan Bohlender, a geneticist at the University of Texas, was doing basic research on a certain population of people and discovered something just didn’t add up. He was researching the genetic information of the Melanesians, native people who live in Melanesia in Papua New Guinea.
Genetics analysis has shown that the native people of this region have high amounts of two ancient human lines, Neanderthals and Denisovans. People around the world may carry a little bit of this type of ancient DNA, but the native people of Melanesia carry it up to 4%, which is the highest researchers have seen. Even though the presence of ancient human DNA was found and seemed nothing new, another third presence of ancient DNA was found in their genetic code. And this was a mysterious type, no one had ever seen or accounted for.
This third “alien” DNA couldn’t be linked to anything, which made a twist to human evolution. What are some speculations are that this third type of DNA may have been related more with the Neanderthals and Denisovans, which may have mixed and extinct later. The only clue we have from this “mysterious” link is by their DNA.
The native people of Melanesia have a lesser amount of Neanderthal DNA, and a higher amount of Denisovans and the third, mysterious type of DNA. Denisovans DNA was recently discovered in the Denisova Cave in Russia and dates to an ancient human DNA lineage. People in Siberia and even down to Asia had shown the presence of these archaic genes.
What leaves this third mysterious DNA a mystery is that unlike the Denisovans and Neanderthal DNA, there aren’t any physical remains to compare it with.
Dr Bohlender goes on to say:
“‘Overall, our findings confirm the human family tree is more complicated than we think it is.”
The native people of Melanesia also showed another shocking superpower in their DNA — they were able to become resistant to viruses, increase their blood glucose levels and break down fats, just by their unique metabolism thanks to their “uncommon” and “alien-like” DNA.
