At varied factors within the final 300,000 years, Denisova Cave has sheltered three completely different species of hominins. However with fossils from solely eight people—4 Denisovans, three Neanderthals, and the daughter of a Neanderthal/Denisovan pairing—it’s laborious to inform an in depth story about when every species lived within the cave. In accordance with a current genetic research, nevertheless, the Denisovans had been the primary, arriving round 250,000 years in the past. They usually should have been there when the primary members of our species arrived round 45,000 years in the past.

That timeline is the results of a current research of mitochondrial DNA (genetic materials handed immediately from mom to youngster) blended into the deep layers of sediment masking the cave ground. The fragments of historical DNA most likely got here from a combination of feces, decomposing stays, and shed pores and skin and hair that ended up blended with the filth of the cave ground, in line with archaeologist Elena Zavala of the Max Planck Institute for Evolutionary Anthropology, lead creator of the research.

“We all know that DNA can bind to the minerals discovered within the sediments and we have now additionally seen microfossils when analyzing the sediments beneath a microscope,” she advised Ars in an e mail. “Future research linking particular parts of the sediment to DNA preservation will assist enhance our understanding of this course of.”
