An article published in the journal “Nature Communications” reports the discovery in today’s Laos of a tooth that was attributed to a little girl that belonged to the Denisovan species, an archaic human species still mysterious in many ways. The molar was dated between 164,000 and 131,000 years ago from the analysis of the sediments in which it was found in the Cobra Cave (Tam Ngu Hao 2), in the Annamite Chain, in Laos. The warm and humid conditions in that area offer little hope of still finding pieces of DNA but the proteins and appearance of the molar, very similar to that of a jawbone discovered in Tibet and attributed to a Denisovan, led the researchers to that conclusion.
