the whole thing about women having generally longer legs and shorter torso is also not statistically significant either, i understand
I found a decent study of human limb and torso lengths vs height when there was another one of these threads, which had studied lots of skeletons in the USA - it might have been connected with the Smithsonian. Anyway, it found that there is no difference in average proportions between men and women, despite the oft peddled myth.
There is a difference between white and black people, with white people having evolved longer torsos (along with longer narrower noses) as an adaptation for colder weather. Obviously that was based upon US data so basically Northern European origin vs West African. I don't know if it remains true for all races from cold vs warm climes but that would be logical.
