Prerequisite: BIOL 22a.
"Nothing in biology makes sense except in the light of evolution," Dobzhansky said famously. Evolution is a unifying theory of biology because it explains almost everything about the living worldboth the diversity of life and the similarities among organisms. This course examines processes and patterns of evolution, including the origin and fate of variation, natural and sexual selection, inbreeding and genetic drift, the evolution of sociality, the species concept and the origin of species, biodiversity, and phylogenetics, as well as the history of life on Earth, including the fossil record and human evolution. Usually offered every year.
