The genetic map of Europe, which shows the genetic relationships between various European populations and which was published in Current Biology, “bears a clear structural similarity to the geographic map,” the New York Times’s Nicholas Wade writes. “The major genetic differences are between populations of the north and south (the vertical axis of the map shows north-south differences, the horizontal axis those of east-west). The area assigned to each population reflects the amount of genetic variation in it.” Finland is quite divergent, as is, to a lesser extent, southern Italy. Thanks to Richard for the link.
