ASHEVILLE, N.C. (BP) – The analysis of an old human tooth seems to have taken another bite out of the evolutionary narrative.
The discovery is expected to lead to a growing body of scientific evidence suggesting that Neanderthals, Denisovans and modern humans belong to one species. Although it seems to invalidate the theory that humans are descended from archaic subspecies that have emigrated from Africa, it fits quite well into the biblical narrative.
The tooth, discovered in the karst cave of Baishiya in Xiahe, China, nearly 40 years old is a three-root, lower second molar evolutionary scientist dates to 160,000 years and is much older than researchers expected. Scientists previously thought that the three-rooted Molar had originated in Asians long after the dispersion of Homo sapiens from Africa.
Three-toed molars are present in 40 percent of the Asian population today – Asian individuals.
The new analysis, which appeared last week in the Proceedings of the National Academy of Sciences, identified the sample as Denisovan tooth. Evolutionary scientists believe that Denisovan is an extinct archaic human and sister species of Neanderthals.
The presence of a three-root tooth in the older Denisovan specimen contradicts the idea that Homo sapiens later developed the trait itself. According to the researchers, Denisovans are more likely to mix with Homo sapiens. And where there is an intersection, there is a strong case that the two species are actually the same.
The discovery that Denisovans are likely to cross with modern humans shows that "the Denisovans and the modern Chinese are the same species as the Neanderthals and the modern man!" Jerry Bergman, a doctor, science professor and author, wrote about Creation Evolution Headlines.
The Bible says that after the Genesis flood, people who were expelled from Babylon and groups of humans were isolated.
Elizabeth Mitchell wrote in an Answers article in Genesis that isolation limited genetic variability and produced ethnic groups such as Neanderthals and Denisovans.

There is also increasing evidence that patterns of dispersion do not support the emergence of evolution from Africa.
