Symmetry, attractiveness,
and developmental stability among "biracial" and "uniracial" individuals.
Developmental
stability, reflected in an organism's bilateral symmetry is strongly associated
with longevity, health, and fitness. Symmetry and developmental stability
have also been shown to increase with an organism's heterozygosity. To
the extent that greater levels of heterozygosity occur among the offspring
of human biracial couples than among those of within-race matings we should
expect similarly increased developmental stability in these biracial individuals.
I will discuss some of my ongoing research on both symmetry and attractiveness
among biracial individuals relative to individuals whose parents are both
from the same race and relate it to the broader issue of heterozygosity
as a determinant of homeostasis.
