The capacity for language is of course a complex "trait" resulting from the interactions of many different physiological and neuroanatomical traits, thus there is no simple "mutation" involved. The selective pressures involved can be summed up in the concepts of socialization and cooperative hunting. That is, improved communication within a band if early "ape-men" would lead to increased efficiency in hunting and reduced social friction between troup members. Social structures could be formed and maintained with less of the potentially damaging fighting typical of other primates, resulting in a generally stronger band. These factors would lead to a greater succes for the band and other bands like it, which is, essentially by definition, a selective advantage for improved communication. Over time these improvements would easily accumulate until the complete adaptive suite we see in modern humans was attained, giving full language competancy. -- Sarima (Stanley Friesen) {trwrb|allegra|cbosgd|hplabs|ihnp4|aero!uscvax!akgua}!sdcrdcf!psivax!friesen or {ttdica|quad1|bellcore|scgvaxd}!psivax!friesen
