James Howard responds:
We continue to use race, because there are differences in groups of people that
obviously separate them. Since these differences overlap, it is important that
a "working definition" exist. Just below is my definition; it is based on gene
expression. This form of gene expression may be affected by the environment and
interbreeding. It is somewhat plastic, therefore, I think it directly
participated in hominid evolution.
