Environmental Change and Human Evolution

You need to discuss the specifics of the two articles. Three-time periods are reviewed in the article:
2.9 to 2.4 million years ago
1.9 to 1.6 million years ago
195,000 years ago until 123,000 years ago
Describe what happened in each time period! What were the environmental changes? There are four different
species that you need to discuss: Australopithecus afarensis, Paranthropus sp., early Homo, and Homo
sapiens. Discuss all four. Which one fits with which time period? Tell me how they changed physically,
behaviorally, and culturally.
