Comparison of inferred spread of farming from archaeological sites and spread of NEOL (A) and YAM (B) ancestries. A and B, Left define first arrival as the first time slice in which a grid point has more than $50\%*an{c}_{MAX}$ of the ancestry depicted, where $an{c}_{MAX}$ is the maximum value that ancestry reaches at that point throughout the entire timeline. A, Center and B, Right are the result of using a more strict cutoff: $75\%*an{c}_{MAX}$ ancestry. A, Right is a spatially kriged map of first arrivals of farming practices, based on radiocarbon-dated archaeological sites.
