Explore the dark side of evolution in this lecture that examines how evolutionary conflicts manifest in nature through infanticide, siblicide, and sexual antagonism. Delve into the biological mechanisms and selective pressures that drive these seemingly destructive behaviors, understanding how they actually serve adaptive functions in the struggle for survival and reproduction. Learn about parent-offspring conflicts, sibling rivalry that leads to siblicide, and the evolutionary arms race between males and females that results in sexual antagonism. Analyze case studies from various species to understand how these conflicts shape behavior, morphology, and life history strategies. Discover the theoretical frameworks that explain why natural selection can favor behaviors that appear harmful to individuals or groups, and examine the conditions under which these conflicts arise and persist in populations.
