Who surivived in England after the last ice age? DNA analysis reveals two distinct groups

Scientists have sequenced the oldest human DNA discovered in Britain and discovered two unique population groups that lived in Britain after the last ice age.

A sample discovered in Gough’s Cave in Somerset, England, from approximately 14,000 years ago, was compared to a sample from approximately 1,000 years later, which was discovered in Kendrick’s Cave, Wales.

“We knew from our previous work, including the study of Cheddar Man, that western hunter-gatherers were in Britain by around 10,500 years ago, but we didn’t know when they arrived in Britain, and whether this was the only population that was present,” said Selina Brace, a principal researcher at the Natural History Museum in Britain, who studies ancient DNA.

By studying the remains found in Gough’s Cave, researchers were able to determine that humans were present in Britain 300 years earlier than scientists had previously thought, meaning they were present before Britain began to warm after the last ice age.
