A new scientific discovery may have shed light on the history of the human species (video below).
Evidence reportedly showed that people in tribes living on the island of Melanesia possess elements of DNA that are completely different than other humans and that have never been seen before.
University of Texas Genetics and DNA scientist Ryan Bohlender conducted a study to see if he could determine how we’re connected to our ancestors, the Neanderthals, and the Denisovans. During the study, Bohlender found that we might actually have a third ancestral carrier.
“We’re missing a population, or we’re misunderstanding something about the relationships,” he said of his research, Newsiosity reported. He concluded that humans might not have the complete view of their species’ history given the research, which is a major breakthrough in DNA and genetics research.
“Europeans have no hint of Denisovan ancestry, and people in China have a tiny amount – 0.1 percent, according to Bohlender’s calculations. But 2.74 percent of the DNA in people in Papua New Guinea comes from Neanderthals,” Tina Hesman Saey said of Bohlender’s research.
“And Bohlender estimates the amount of Denisovan DNA in Melanesians is about 1.11 percent, not the 3 to 6 percent estimated by other researchers. While investigating the Denisovan discrepancy, Bohlender and colleagues came to the conclusion that a third group of hominids may have bred with the ancestors of Melanesians.”
The third species has not yet been discovered.
