Question

Australopithecus, Homo habilis and Homo erectus are the important ancestral stages in human evolution. Compare all three stages in terms of:
(a) Time period of existence
(b) Tools structure and used
(c) Behavior
(d) Remains location

Answer 1

Explanation:

The transition from Australopithecus to Homo is usually thought of as a momentous transformation, the fossil record bearing on the origin and earliest evolution of Homo is virtually undocumented. As a result, the poles of the transition are frequently attached to taxa (e.g. A. afarensis, at ca 3.0 Ma versus H. habilis or H. erectus, at ca 2.0–1.7 Ma) in which substantial adaptive differences have accumulated over significant spans of independent evolution.
