Discussion 5: Ardipithecus Early Hominins date back to at least 6.7 million year

Discussion 5: Ardipithecus
Early Hominins date back to at least 6.7 million years to date. From the previous lecture on earlier primate-like species and from the lectures on the forces of evolution, you know that species change due to environmental pressures. Using the information in the short video on Ardipithecus, provide the specific reasons why this discovery rocked the field of human evolution. Be specific. Use your own words and correct anatomical terminology.
Finally, you cannot use outside sources. The point of the discussions in this class is to demonstrate to me that you understand the material. Using outside sources can easily distract from the points I make in the assignments I assign.
