Race Is Real, But It’s Not Genetic

0 commenti

Alan Goodman spiega su Sapiens parla della definizione di razza.

Geographic ancestry is not the same thing as race. African ancestry, for instance, does not tidily map onto being “black” (or vice versa). In fact, a 2016 study found wide variation in osteoporosis risk among women living in different regions within Africa. Their genetic risks have nothing to do with their socially defined race.

When medical professionals or researchers look for a genetic correlate to “race,” they are falling into a trap: They assume that geographic ancestry, which does indeed matter to genetics, can be conflated with race, which does not. Sure, different human populations living in distinct places may statistically have different genetic traits—such as sickle cell trait (discussed below)—but such variation is about local populations (people in a specific region), not race.
