So thousands of years ago, our ancient relatives, our ancient humans, they crossed hundreds of miles of ice that connected the Bering Strait to the Americas. And there was a new study, it was left by the University of Colorado Boulder, suggesting that these humans, they carried something interesting. There was a chunk of DNA that was inherited from an elk species of hominid, which may have allowed humans to adapt to their new home. And researchers published the results in the journal Science just recently. And the research takes a look at a species known as the Denisodans. And they're ancient relatives of humans that lived in what is the Russian south to Oceania and west to the Baton Plateau. And the Denisodans, likely extinct tens of thousands of years ago, their existence is poorly understood. Scientists identified the first Denisovan about 15 years ago from DNA in a fragment of bone found in a cave in Siberia. And like Neanderthals, Denisovans may have had a prominent browse and no chance.
