Extinct cave bear DNA lives on in brown bears

28.08.2018

Modern brown bears are carrying a bit of genetic material passed down from the cave bear, in a study that suggests extinction does not always vanquish a species’ genes.

The now published study of the complete genome of four cave bears from different regions of Europe from Spain to the Caucasus from the period between 71,000-34,000 BC shows that at least part of this genome is still to be found today in the genome of the brown bear. Ron Pinhasi, from the Department of Evolutionary Anthropology, says, "For the first time ever, DNA from an extinct Ice Age species has been found in a still-living population - apart from the human lineage." still be able to participate in the evolutionary process for tens of thousands of years.
