Document Summary

Coninued from last week: the development of language. Language allowed individuals to more accurately and directly express their desires and intenions. It"s complicated to keep track of everyone"s relaionship. Language is closely ied to complex group interacions. If ur living in a large group, lang is efecive but we use it in an even more complicated way. Trying to convince other people of your acions emoions etc that aren"t actually true: say things that make it seem like you like someone when you don"t, hey are you doing if you answer accurately . The trend in encheophlizaion started 4 millions ago, so no one thinks language showed up a long ime ater. The jump in enchepalizaion maybe shows where language showed up b/ theories on bipedalism. Over the course of homo evoluion, theres been a strong selecion for obligate bipedalism. Humans are using this quadrupeds bone incorrectly, only for 4 mil yrs. Stone tool is only one type of tool.
