For those who are interested:Lahr published the results of her work in
the book "The Evolution of Modern Human Diversity:a study of cranial
variation",Cambridge University Press,1996, 460pp.
See also Daniel E.Lieberman's article "Testing Hypotheses about Recent
Human Evolution from Skulls:Integrating Morphology,Function,
Development,and Phylogeny" in Current Anthropology (1995),
vol 36,nr.2:159-197.
This article provides a critique of the 33 characters most often used
to support hypotheses of recent human evolution. The conclusion is
that the majority do not satisfy three essential criteria;being
homologous,derived,and observable for all taxa.
Of those characters that do satify these criteria,more support the
recent-African-origin hypothesis than the multiregional-origin
hypothesis.
