Did "caucasoid" features originate in Africa?

[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by Cass/: [qb] True, but one would expect to see these features on African fossils if they originated there. We don't. Tooth-size reduction began in Europe. http://www.iu.edu/~semliki/PDFs/BraceRosenbergHunt87.pdf "Human tooth size, crudely considered, was maintained at the same level through- out the Middle Pleistocene. With the onset of the last glaciation in the Late Pleistocene between 75,000 and 100,000 years ago, [b]dental reduction began to occur among the northernmost inhabitants of the Old World[/b] for which we have evidence. Tooth size then began to reduce at a rate of roughly 1 % per 2,000 years until the end of the Pleistocene approximately 10,000 years ago." (Brace et al. 1987) [/qb][/QUOTE]The above may very well explain the below. [QUOTE] Nubia.-Similar trends of Post-Pleistocene dental reduction are also visible beginning in the Mesolithic in Nubia (Calcagno,1983a, 1983b),although there is reason to suspect that Mesolithic tooth size there was as much as 100mm 2 larger than it was in the Middle East and Europe(Greene et al., 1967).[/QUOTE]Gradual Change in Human Tooth Size in the Late Pleistocene and Post- Pleistocene Author(s): C. Loring Brace, Karen R. Rosenberg, Kevin D. HuntSource: Evolution, Vol. 41, No. 4 (Jul., 1987), pp. 705-720Published by: Society for the Study of Evolution [QUOTE] One last question well worth more attention than it has received lies in the curiously specialized, almost more than modern, character of the Boskopoid line. By some writers, the development of Homo sapiens is correlated with civilization. It is pointed out that the Australian aborigines are macrodont and that civilized whites are microdont, and this is sometimes attributed (often with unconscious Lamarckian tendencies) to the influence of high culture. That civilization has had, and is having, vast and unknown effects through selection upon human beings, it is not my purpose to deny. But the big-brained pedomorphic [b]Boskopoids with their trend toward microdont dentition[/b] and reduced faces were no more civilized than the macrodont Australoids.

Scott and Turner 2000; Sperber 1958; Van Reenen 1964, 1966), and dental dimensions can be affected negatively by attrition shortly after eruption due to the nature of Khoesan diet (Van Reenen 1982).
