Brow ridges

Paleolithic humans
Pronounced brow ridges were a common feature among paleolithic humans. Early modern people such as those from the finds from Jebel Irhoud and Skhul and Qafzeh had thick, large brow ridges, but they differ from those of archaic humans like Neanderthals by having a supraorbital foramen or notch, forming a groove through the ridge above each eye, although there were exceptions, such as Skhul 2 in which the ridge was unbroken, unlike other members of her tribe. This splits the ridge into central parts and distal parts. In current humans, almost always only the central sections of the ridge are preserved (if preserved at all). This contrasts with many archaic and early modern humans, where the brow ridge is pronounced and unbroken.
