Document Summary
First homo sapiens appeared about 200, 000 years ago (previously thought to be 160, 000 years ago) (brown, 2005) Were basically referred to as humans with big brains. Groups slowly get bigger humans seem to need to spend about 20% of their time groo(cid:373)i(cid:374)g/pree(cid:374)i(cid:374)g. releases o(cid:454)(cid:455)to(cid:272)i(cid:374) the (cid:271)o(cid:374)di(cid:374)g or (cid:862)lo(cid:448)e(cid:863) hor(cid:373)o(cid:374)e. There is unlikely a genetic cause for even mother/daughter bonds. They arise through touch and communication (nagasawa, 2012) 130,000 years ago, some homo sapiens begin to talk (still some did not have language a group in present-day israel for example did not talk even 100,000 years ago) Need (cid:373)ore effi(cid:272)ie(cid:374)t (cid:862)pree(cid:374)i(cid:374)g(cid:863) / (cid:862)groo(cid:373)i(cid:374)g(cid:863) (cid:894)(cid:272)o(cid:374)(cid:374)e(cid:272)ti(cid:374)g / o(cid:454)(cid:455)to(cid:272)i(cid:374) release(cid:895) = (cid:272)o(cid:373)(cid:373)u(cid:374)i(cid:272)atio(cid:374) the most important part of their environment had become other humans.
