A young girl’s tooth, between 1640,000 and 131,000 years old, was excavated from a cave wall in northeastern Laos. The discovery could help scientists uncover information about an extinct branch of humans, the Denisovans.
The molar, between 164,000 and 131,000 years old, belonged to a girl about 4-6 years old and had not yet erupted.
A tooth believed to have belonged to a young female from the extinct human species called the Denisovans.“This is the first time that a Denisovan has been found in a warm region,” said paleoanthropologist Fabrice Demeter of the University of Copenhagen’s Lundbeck Foundation GeoGenetics Centre, lead author of the study published on Tuesday in the journal“It means that they were adapted to opposite environments, from cold and high altitude to warm and low altitude regions.
Neanderthals possessed a strong double-arched brow ridge, relatively large noses and relatively large front teeth. A common ancestor to Denisovans, Neanderthals, and Homo sapiens is thought to have lived in Africa 700,000 to 500,000 years ago, with a branch that led to Denisovans and Neanderthals splitting off 470,000 to 380,000 years ago. Homo sapiens first emerged in Africa roughly 300,000 years ago, then spread worldwide.
