ANT101H5 Lecture Notes - Lecture 10: Homo Rudolfensis, Olduvai Gorge, Richard Leakey
Document Summary
General trends of early homo in comparison to australopithecines. Back teeth still quite large (but < australopithecines) Hammerstone bipolar percussion - rock used to strike flakes off cobble. Anvil (cid:0) direct percussion - large rock that you strike the cobble against or place the cobble on cobble against or place the cobble on. Flake - chip of rock off the cobble - sharp, useful edges - scrapers. New additions to diet: meat group sharing scavenging. Probably resulted from an adaptation to a new environment. 1st hominin species to exist outside of africa an african origin an impressive longevity. Best collection of 600,000 (cid:0) 300,000 yr old hominids ever found. Minimum 40 individuals (cid:0) adult male, female & subadults. Inconsistencies in the chronological transition of morphological changes from h. habilis to h. ergaster to h. erectus. Teeth larger than modern human, but smaller than h. habilis. Conical rib cage (different from humans who have barrel shaped rib cage)
