A new study by Stanford University biologists finds an explanation for the idea that physical characteristics such as skin pigmentation are “only skin deep.” Using genetic modeling, the team has found that when two populations with distinct traits combine over generations, traits of individuals within the resulting “admixed” population come to reveal very little about individuals’ ancestry. Their findings were published March 27 in a special edition of the American Journal of Physical Anthropology on race and racism.
