In addition to agricultural know-how, the intrepid farmers brought their genes: They interbred with hunter-gatherer communities to create modern humans living in Europe today.
"Genetic variation of today's Europeans was strongly affected by immigrant Stone Age farmers, though a number of hunter-gatherer genes remain," study researcher Anders Götherström, of Uppsala University in Sweden, said in a statement.
The results of this study, to be published in the April 27 issue of the journal Science, match up well with previous archeological evidence of farming in Europe.
