and 50,000 years of genetic isolation.
"Thorin", one of the last Neanderthals to walk the planet, was part of a previously unknown lineage that was isolated for 50,000 years, a new analysis of his DNA finds.
Discovered in 2015 at the entrance to the Grotte Mandrin rock shelter in the Rhône River valley of southern France, Thorin — nicknamed after a dwarf in J. R. R. Tolkien's "The Hobbit" — has sometimes been called the "last Neanderthal" because he may have lived as recently as 42,000 years ago, close to when our closest human relatives disappeared. Although only his teeth and portions of the skull have been recovered so far, Thorin's genome was analyzed to better understand when and how Neanderthals disappeared.
