Gideon Lewis-Kraus writes for the NY Times on the promise and problems of ancient DNA: Imagine that the written history of our current era were lost to time, and paleogenomicists of the future were trying to explain the peopling of North America on the basis of a few bones that dated from between the 16th and 20th centuries. If these bones included the descendants of British, Spanish and French colonists as well as those of Yoruba slaves, the researchers might conclude that European migrants arrived together with African migrants and that their “sex-biased admixture” created the people known henceforth as Americans. From our perspective, those geneticists wouldn’t exactly be wrong about all this — but nobody would accuse them of being right, either.
