The genetic ancestry of the earliest Europeans survived the ferocious Ice Age that took hold after the continent was initially settled by modern people.
That is the suggestion of a study of DNA from a male hunter who lived in western Russia 36,000 years ago.
His genome is not exactly like those of people who lived in Europe just after the ice sheets melted 10,000 years ago.
But the study suggests the earliest Europeans did contribute their genes to later populations.
Europe was first settled around 40,000 years ago during a time known as the Upper Palaeolithic.
But conditions gradually deteriorated until ice covered much of the European landmass, reaching a peak 27,000 years ago.
The ice melted rapidly after 10,000 years ago, allowing populations from the south to re-populate northern Europe - during a time known as the Mesolithic. But the genetic relationships between pre- and post-Ice Age Europeans have been unclear.
Some researchers have in the past raised the possibility that pioneer populations in Europe could have gone extinct some time during the last Ice Age.
And one recent study looking at the skull features of ancient Europeans found that Upper Palaeolithic people were rather different from populations that lived during the later Mesolithic period.
In the latest study, an international team of researchers sequenced the genome (the genetic "blueprint" for a human) of a man buried in Kostenki, Russia.
They discovered a surprising genetic "unity" running from the first modern humans in Europe, through to later peoples. This, they claim, suggests that a "meta-population" of Palaeolithic hunter-gatherers managed to survive the Ice Age and colonise the landmass of Europe for more than 30,000 years.
"That there was continuity from the earliest Upper Palaeolithic to the Mesolithic, across a major glaciation, is a great insight into the evolutionary processes underlying human success," said co-author Dr Marta Mirazón Lahr, from Cambridge's Leverhulme Centre for Human Evolutionary Studies (LCHES).-READ MORE-http://www.bbc.co.uk/news/science-environment-29940694

First Europeans 'weathered Ice Age'
