In the thread To Those That Think I'm A Racist I posted the results of scientific research showing that races have different bone densities, and that these differences persist after adjustment for environmental variables. This was in response to quadraphonic's repeated claims that race is just a sociological construct, ie, it has no basis in objective, scientific fact.
I repost that research here, along with journals that have cited the research (the full pdf is available at the source site for those who are interested):

The scientific evidence supports the assertion that races have a measurable, physical reality.

Racial Differences in Bone Density between Young Adult Black and White Subjects Persist after Adjustment for Anthropometric, Lifestyle, and Biochemical Differences.
The Journal of Clinical Endocrinology & Metabolism Vol. 82, No. 2 429-434 Copyright © 1997 by The Endocrine Society
This study tested whether racial differences in bone density can be explained by differences in bone metabolism and lifestyle. A cohort of 402 black and white men and women, ages 25–36 yr, was studied at the Kaiser Permanente Medical Care Program in Northern California, a prepaid health plan.
Bone density at all skeletal sites was statistically significantly greater in black than in white subjects; on average, adjustment for covariates reduced the percentage density differences by 42% for men and 34% for women.We concluded that racial differences in bone mineral density are not accounted for by clinical or biochemical variables measured in early adulthood.
By using DXA area measurements, we confirmed that young, adult, black men and women have substantially greater BMD (Bone Mineral Density) than white persons (2– 6); this finding is true at all skeletal sites, and we have extended these observations to volumetric estimates of spinal BMD. Despite an extensive search for clinical and biochemical explanations, we were unable to account for most of the racial differences in BMD.
By midadolescence, black boys and girls have 10–15% greater bone density than their white counterparts (33). However, most of the difference would be expected to remain evident 10–20 yr later. Thus, the appearance of such a large racial difference in young adults cannot be attributed to persistent differences in metabolic or lifestyle factors...
