Differences between gracile and robust australopithecines
What are the similarities and differences between gracile and robust australopithecines? What, if anything, can this tell us about their lifestyle (such as, but not limited to, diet, social structure, etc.) and the environment in which they lived? Finally, explain if you think robust hominids should be in the genus Australopithecus or Paranthropus.

Explain how epigenetic modifications provide an important mechanism
Explain how epigenetic modifications provide an important mechanism for developmental changes that lead to specialized body parts and cell types. How do the protein complexes called trithorax and polycomb group complexes participate in this process?
