Proportions from Faces Yann C. Klimentidis, Mark D. Shriver
Ethnicity can be a means by which people identify themselves and
others. This type of identification mediates many kinds of
social interactions and may reflect adaptations to a long
history of group living in humans. Recent admixture in the US
between groups from different continents, and the historically
strong emphasis on phenotypic differences between members of
these groups, presents an opportunity to examine the degree of
concordance between estimates of group membership based on
genetic markers and on visually-based estimates of facial
features. We first measured the degree of Native American,
European, African and East Asian genetic admixture in
