Question

4. Australopithecine success and adaptations are a constant source of discussion. a. Some researchers believe that early Australopithecus success can be attributed to tool using. Explain the logic and the evidence (if there is any) that backs this assertion. b. While early Australopithecus success is difficult to understand, some later Australopithecines have clear dietary specializations that aided in their long existence on the savannas. Explain the adaptive advantages associated with Robust australopithecines. Explain the traits and why you think this was helpful to these hominins.

Answer 1

Australopithecus iis a collection of Homonin species that lived 4.18 - 2 million years ago. Bone fossils found in Euthopia indicated use of stone in butchering animals. Also they showed presence of canine teeth which indicates meat was a part of their diet.

More massive skulls and larger teeth make a hominin robust,Key features were having a larger brain, and eating harder foods like seeds and nuts. These features allowed individuals to crush and grind hard foods such as nuts, seeds, roots, and tubers in the back of the jaw which helped them survive in the savansa.
