ond, is differencesin geography and climate. The third is human biodiversity. Let's look atthree physical differences between the races. 1) Asian men tend to beshorter than white and black men. Does this matter in the mating game? Oneof America's leading hands-on researchers into this question, 7'1",280-pound basketball legend Wilt Chamberlain, reports that in his ampleexperience being tall and strong never hurt. Biological anthropologistsconfirm this, finding that tal- ler tends to be better in the eyes of mostwomen in just about all cultures. Like most traits, height is determined bythe interaction of genetic and social factors (e.g., nutrition). Forexample, the L.A. Dodgers' flamethrowing pitcher Hideo Nomo is listed as6'2", an almost unheard-of height for any Japanese man fifty years ago,owing to the near-starvation diets of the era. While the height gap betweenJapanese and whites narrowed significantly after World War II, this trendhas slowed in recent years as well-fed Japanese began bumping up againstgenetic limits. Furthermore, it can be rather cold comfort to a 5'7" Asianwho is competing for dates with white and black guys averaging 5'11" tohear, "Your sons will grow up on average a couple of inches taller than you,assuming, of course, that you ever meet a girl and have any kids." Incontrast, consider a 5'1" Asian coed. Although she'd be happy with a 5'7"boyfriend if she were in an all-Asian school, at UCLA she finds lots of boystemptingly much taller than that, but few are Asian.2. This general principle -- the more racial integration there is, the moreimportant become physical differences among the races -- can also be seenwith regard to hair length. The ability to grow long hair is a usefulindicator of youth and good health. (Ask anybody on chemotherapy.) Sincewomen do not go bald and can generally grow longer hair than men, mostcultures associate longer hair with femininity. Although blacks' hairdoesn't grow as long as whit...
