An innovative method reveals that an ancient trinket was handled by a woman some 20,000 years ago.
“It’s almost like you open a time travel machine,” says study co-author Elena Essel, a molecular biologist who works on ancient DNA at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. “With each sample we are able to learn a bit more and make more inferences about how these people lived.”An animal’s genetic material is stored deep within the pores of its bones and teeth.
Mitochondrial DNA — which is handed down from mother to offspring — extracted from the pendant show that the object is roughly 19,000 to 25,000 years old and that the tooth belonged to a wapiti, also known as an elk . Analysis of nuclear DNA from the ornament suggests that it had been made or worn by a femalewhose genetic make-up resembles that of north Eurasian individuals who lived around the same time but were previously known only from remains found farther east in Siberia.
