People moved east to west, less so north to south. See how the differently colored clusters form distinct horizontal bands? The red, blue, purple, and green dots fan out from right to left. This pattern means DNA confirms the descendants of immigrants to the East Coast moved westward.While people certainly moved back and forth from the north to south as well, if people had moved in the same volume from north to south, you’d see the bands fanning downward and not just from east to west.But instead you can see powerful forces pushed people westward, even showing that the Mason-Dixon line separates some of the clusters. Catherine Ball, chief scientific officer at Ancestry and the leader of the study, commented to Wired: “I have to admit I was surprised by that. This political boundary had the same effect as what you’d expect from a huge desert or mountain range.”
