DNA From An Unknown Human Species Has Been Detected In Pacific Islanders

Surely you’ve heard the phrase “missing link” when it comes to evolution, but perhaps you’re unsure of what it means. The “missing link” theory is the idea that human evolution has a distinct series of species evolution that leads up to modern human, or homo sapiens. We already know some of those species and in what order, or however they evolved, like Neanderthals and homo-habilis, both early human-like species. We know that that these species eventually led to the evolution of modern human through morphological analysis (they look like humans) and also molecular analysis (DNA similarities).

We know of at least 12 different genuses within the homo species, and also a couple others that were similar to current species. Today, DNA analysis of extant humans has unveiled a possibly new homo genus that has not yet been identified. As the world of science further dissects the human genome, we can look more and more closely at the differences between populations and pull together the story of human evolution even better.

A recent analysis of extinct hominid DNA in extant human DNA, particularly in Pacific Islander populations, has shown a new lineage of human ancestry. In Pacific Island DNA, scientists have found remnant ancient human DNA has led to a new discovery that may have evolutionary scientists going back to their drawing boards.

Scientist Ryan Bohlender has found data to suggest that a third group of hominids, separate from Neanderthals and Denisovans (which are common DNA fragments in most humans today).

Bohlender found that in the DNA of modern Pacific Islanders, there is significant overlap between that of the Denisovan genome (which was only discovered in 2008) and present day east Asian populations. Most Asian populations have about 0.1 percent of Denisovan DNA, indicating that something different is going on here.

Alternatively, he suggests that maybe there is not a third population, but perhaps a misunderstanding about the relationship between early humans that needs to be reanalyzed.
