ANTH 101 Lecture Notes - Lecture 12: Paranthropus, Homo Habilis, Louis Leakey
Document Summary
Eventually, the robust australopithecines (or paranthropus) went extinct. Most likely, the gracile australopithecines evolved into later homo. Australopithecines little evidence of tool use, only found in africa definitive bipedalism. The differences suggest that the robust species evolved for eating tough plants. The leakeys were able to date the fossil to 1. 75 to 0. 25 mya using the new potassium- argon dating method. Zinj was later renamed a. boisei (or p. boisei) Mary and louis leakey discovered the first fossils of h. habilis at oduvai gorge in. The leakeys found human remains in association with stone tools, and thus named the species h. habilis. H. habilis dates from 2. 4 to 1. 5 mya. The cranial capacity of h. habilis is 550-800 cm3. There are at least 8 to 10 recognized species of homo. They range in date from ~2. 4 mya to the present and are now found on all continents. Humans have cranial capacities that range from 500 to 1350 cm3.
