Talk:Brow ridge

I edited the section which read "The closest living relatives of man, the Great Apes, have very pronounced supraorbital ridges. The evolution of man therefore is thought to have included a gradual reduction of the ridges. The size of the ridges is typically used as a rough indicator of date and therefore of stage of evolution." because it was uncited and untrue. Evolutionary theory says nothing about development in "stages," and the supraorbital tori of hominids have been found to "grow" and "shrink" over time without any clear progression.
