Develop a comprehensive analysis of modern evolutionary theory. Explain the mechanisms of natural selection, genetic drift, gene flow, and mutation, including their relative importance in different evolutionary scenarios. Discuss the levels of selection debate (gene, individual, group). Analyze major evolutionary innovations including multicellularity, sexual reproduction, and social behavior. Apply evolutionary theory to explain the evolution of cooperation through kin selection, reciprocal altruism, and group selection models. Discuss how evolutionary theory integrates with other biological disciplines including developmental biology, ecology, and genomics.
