Scientists have produced a digital image of a genome tens of thousands of years old with the resolution of a typical living person's, enabling them to describe the life of prehistoric humans in great detail, they reported in Thursday's issue of Science magazine. <\/p>\n
Led by Svante Paabo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, the scientists have created the highest-quality genome sequence of prehistoric humans yet. <\/p>\n
Therefore, the Denisovans as the group has been called after the Siberian cave harboring its fossils: a finger bone and two teeth are much better known genetically than Neanderthals, although there are hundreds of specimens from them. <\/p>\n
There is no difference in what we can learn genetically about a person that lived 50,000 years ago and from a person today, Paabo said Wednesday in a conference call with reporters. <\/p>\n
The international team of researchers used only genetic material from a tiny finger bone from a girl that lived in Siberia tens of thousands of years ago. The specimen was found in a cave in 2008 and, based on preliminary genetical analyses by the team in 2010, was attributed to a novel group of humans closely related to Neanderthals. <\/p>\n
The scientists owe their insights mainly to new technological advances in sequencing of prehistoric DNA. <\/p>\n
All forensics on ancient DNA were originally developed for modern DNA, said Matthias Meyer of the Max Planck Institute, lead author of the article. <\/p>\n
He was responsible for developing approaches that take into account challenges typical for prehistoric genetic material, such as its scarcity and degraded state. <\/p>\n
Using the DNA, the scientists reconstructed the appearance of the Siberian girl: She had brown eyes and dark hair and skin. <\/p>\n
Also from genetic information, the scientists pieced together the girl's pedigree and compared it with that of modern humans and Neanderthals. <\/p>\n
