Summary

Story summary

Research from Penn State indicates migration was the main factor in the spread of farming in prehistoric Europe.
A study in Nature Communications found cultural transmission contributed only 0.5% to agricultural practices.
Inter-group mating was infrequent, with under 3% of farmers and foragers mixing, resulting in distinct genetic lineages.
These findings may lead to a reevaluation of other prehistoric cultural changes using genetic and archaeological data.
