Prognathous:
Prognathy is the typical condition in most Hominid species and was found in almost all prehistoric humans. Today centres of prognathy lie in sub-Saharan Africa as well as Native Australia. In a milder form it occurs in Melanesia and New Guinea, parts of Indonesia, South Asia, and even in mountain regions of the Middle East. In America prognathy is especially found in some Lagids and Fuegids, but hardly as strong as in Africa and Native Australia. In Europe some of the more ancient types (e.g. Paleo Atlantids) can show mild prognathy. Milder forms include alveolar prognathism.
