Hominid Diet Reconstruction Disscussion

Discussion points for the Sponheimer and Lee-Thorp 2003 paper for March 5th

Here are just some things to think about that we found interesting and you might have some thoughts on:

First of all, did this paper present information about Australopithecines that you found surprising?

Do you agree with the conclusion that these hominids’ more generalized diet allowed more adaptable success? Especially in regards to environmental change? And how do you think this is related to increases in brain size?

How does diet generalization steer evolution (or does it) in hominids and other organisms?

Does the limited number of individuals (dominantly from South Africa) detract from the validity of the trends presented in this paper?

Any thoughts about how further studies may work to clarify the questions presented in this paper and/or incorporate information to add validity?

Strengths and weaknesses of the analysis techniques used?

Impact that a seasonally variable diet may have on this (i.e. huge teeth and microwear consistent with processing hard foods during a certain season that only accounts for a small portion of its annual consumption)?

These are just some questions, we hope you found the article at least a little interesting and invite any additional questions, comments, or objections!
