ANTH 410 Chapter Notes - Chapter 1: Parallel Evolution, Multilinear Map, Divergent Evolution
Document Summary
Questions: steward pdf article and m & w the patrilineal band : towards the beginning of the pdf article, steward talks about convergent and parallel evolution. Steward is almost certainly more concerned with the role of parallel evolution in cultural evolution. He discusses at length the dismissal of divergent trends as the result of differing environmental factors and unimportant to the ultimate picture of following of general trends which is seen in parallel evolution. Regardless steward time and time again throughout the article dismisses concepts key in convergent evolution like diffusion, clearly indicating that he is far more concerned with parallel evolution in the process of cultural evolution. Convergent or divergent evolution applies more to evolutionary biology vs. cultures. For parallel evolution have to have a common ancestor but according to darwinian science everything has a common ancestor ultimately. The general phenomena is convergence but parallel phenomena are a special case of convergence. Homology: similar due to a common ancestor.
