BIO 346 Lecture Notes - Lecture 20: Archaic Humans, Homo Habilis, Homo Erectus
Document Summary
Oldowan simple cores with flakes shaved off. Transition from simple cores to to acheulean stone tools see the emergence over time. Neanderthals and early homo sapiens before we are behaviorally modern. Mousterian tools - spear tips, complex, attached to handles (bone/antler/horn) Upper paleolithic (last 50,000 years ago - last neanderthals in southern spain 28 kya) Venus figurines, flute (35 kya) & art (cave art) Marks behaviorally modern people - have mastered the world enough + mental capacity to be able to create things. Behavior (ability to make certain kinds of tools) - synapomorphy. Brain size - gets bigger over time (swelling of brain case) Origins of behavioral complexity & antecedents in other species. Quantified reports of aggression that resulted in death from lots of species. Based on phylogenetic relationships use numbers to see what you would expect for certain species. Estimates close to those in the paleolithic period - all hunter-gatherers.
