Description
Step 1: Read Katherine Gibsons article Epigenesis, Brain Plasticity, and Behavioral Versatility:Alternatives to Standard Evolutionary Psychology Models. In Complexities: Beyond Nature and Nurture(2005), pp. 23?33 and 37 bottom-38 (excerpt of a longer chapter; difficult)
Step 2: As you read, pay attention to the following terms and make sure you understand them:
1. Environment of evolutionary adaptation (EEA)
2. Standard evolutionary psychology models (SEPMs) these are misconceptions Gibson refutes
3. Epigenesis
4. Pleiotropy
5. Neural plasticity
Step 3: Write one sentence summarizing the ideas Gibson is criticizing (these are the SEPMs).
Step 4: Make a bullet-pointed list of the key pieces of evidence Gibson provides to support her ownargument that the EEA was highly variable rather than stable, and that its variability indicates theimportance of brain plasticity in the evolution of modern homo sapiens. Aim for 5+ bullet points.
Step 5: What does Gibson mean when she writes that brains are also epigenetic organs in theanatomical sense (p. 31)? Write two sentences explaining this. Is her information consistent with, or doesit contradict, the arguments you read about previously in Mahler and Twilley?
