Not everything over there is fully functional yet, and the internal links still point to this blog, and will for the indefinite future.So all the old material will be left here for archival purposes, with comments turned off.Obviously individuals and populations exhibit genetic relationships to each other contingent upon the patterns of the variation of base pairs (A, C, G, and T) across the genomes of individuals, but there’s no reasonable way to comprehend this “by eye” when you’re talking about hundreds of thousands of markers.The authors used two simple methods to infer clustering within the data set. This method is one where the independent dimensions of variation within the data set of the markers are pulled out.Each individual then has a value position on the dimension, dependent on how that individual relates to the others.When you take multiple dimensions and transpose the data geometrically you quickly see population structure fall out of the data set.
Observe that the density seems to decrease as you approach the European American cluster.
In fact this is very close to the estimates which were produced by genealogists.
The concordance of these methods is reassuring, since the underlying phenomena is the same.
My primary concern is that here we have two literary intellectuals arguing about a complex topic which spans the humanities and the sciences.
Ta-Nehisi, as one who studies history, feels confident that he can dismiss the utility of racial population structure categorization because as he says, “no coherent, fixed definition of race actually exists.” I am actually more of a history guy than a math guy, not because I love history more than math, but because I am not very good at math.
