AN 103 Study Guide - Midterm Guide: Acheulean, Homo Erectus, Neanderthal
Document Summary
: environment, fossils (non-human primates, hominin ancestors), extant primates (primatology). Smaller zygomatic bone / bipedalism: the australophithicines: lucy 3-4 million years ago in east africa. Bipedalism fsho, mix of human and apelike features, small brain size (ie. australopithecus aferensis: homo habilis: 1. 6-2. 5 million years ago, found in east and south africa. Marks the beginning of the paleolithic time period (stone tools!) Requires planning and intelligence: homo erectus: 1. 8-200,000 bps, found in africa, asia, and europe (species is adaptable). Had a huge brain capacity, skull is rounder projecting the nose, completely bipedal, has culture, tools, evidence of hunting (fires, scavenging, and housing: pleistocene epoch: 1. 7-10,000 b. p. Glacial: much colder than present/widespread ice and snow cover. Interglacial periods: temperature approached and equaled out: acheulean handaxe: typifies homo erectus, about 1. 4 million years ago. Bifacial, hard/soft hammer techniques used for butchering, chopping and digging: homo neanderthalensis: around 600,000 to 400,000 years ago at the burst of evolutionary change.
