ANTHRO 101 Lecture Notes - Lecture 20: East Los Angeles College, Gluteus Maximus Muscle, Homo Ergaster
Document Summary
East and south africa 1. 8 mya. Cooler climate entering ice age (due to change in earth"s tilt) Derived super-orbital (lots of bone by the eye along the brow ridges) and occipital torus (back of the head) unique to h. ergaster, flatter face, higher skull, small teeth. Same body proportions as modern humans fully terrestrial. Modern pelvis (birth canal relative to skull size similar to modern humans) Found 5 crania in georgia 1. 8 mya. Some in china 1. 8 mya-30 kya. Lots of bamboo in asia maybe used as tools instead of stones. Entered europe from africa to spain, italy. Thicker skull, larger faces, pronounced occipital torus and brow ridge, sagittal keel (thickening between parietal lobes centre of skull; not linked to sagittal crest), stockier build (due to colder climate) relative to h. ergaster. Removal of cortex in pebbles to create a sharp edge all around. Tool maker had a design in mind.
