About a week ago I put up a post put on an analysis of a paper which reported on the ancestral make up of 50 Cubans (as well as assorted other Hispanic/Latino groups). One aspect of the paper which was somewhat notable is that 1 out of 3 Cubans were 90 percent or more European in ancestry. The notability of this is that is that 5 out of 6 Cuban Americans identify as white. That is, of European ancestry. The main caveat here is that these Cubans were sampled from New York City, and to a lesser extent the Midwest. The fact of non-European admixture in putatively white European individuals from Latin America is not surprising. Our prior expectation should be that the admixture is non-trivial, though not preponderant. For example, the majority of the white population of Argentina has Amerindian ancestry (or, more precisely ~15 percent of the aggregate ancestry of Argentineans is Amerindian). At least notionally Cuba is a much more racially mixed culture than Argentina, so non-white admixture in even white Cubans is not surprising.
Based on the above paper (and the data which you can find on other Latin American whites), as well as …
