What do we know about the early evolution of the human lineage? Beginning with the first human fossils, describe some of these fossils, listing the sites where they were found. How did these fossils differ morphologically from modern humans, and what was the paleoenvironment like when these fossils were once alive?
Added by Denise D.
Step 1
The earliest known human fossils belong to the species *Homo habilis*, which lived approximately 2.4 to 1.4 million years ago. Other significant early fossils include *Australopithecus afarensis*, with the famous specimen "Lucy" dating back to about 3.2 million Show more…

1. Describe the climate during the early Pleistocene. Explain why climate is important for understanding the evolution of early Homo. 2. List the key anatomical characteristics that are generally agreed to define the genus Homo. 3. Why has classification of early Homo fossils proved difficult? What are some explanations for the variability seen in these fossils? 4. Compare and contrast the Oldowan and Acheulean tool industries. 5. Name some specific behaviors associated with Homo erectus in the areas of tool use, subsistence practices, migration patterns, and other cultural innovations.

The earliest hominin fossil evidence to show a direct connection to non-human primates were Eoanthropus dawsoni and Australopithecus africanus. These were both discovered and identified in the early 20th century, but they contradicted each other. What was different about the morphology of the two specimens and what did these different morphologies suggest about the course of human evolution? Which specimen ultimately represented the current paradigm and why? (200-250 words)
Talk about early hominid fossil record. Name at least THREE hominids that predated modern Homo sapiens. Describe at least two physical differences for each.
