Evolution is the generation to generation change in the frequency of alleles in the gene pool and the division of populations into lineages. That this occurs is a fact. Evidence for the modes and tempos of evolution coming from laboratory genetics, population genetics, natural history, systematics, and paleontology, is so overwhelming that no scientific discipline refutes evolution. Understanding this concept is crucial to understanding all disciplines of biology including but not limited to ecology and evolutionary biology, cellular and molecular biology, and medicine. Therefore, the Biological Sciences program integrates evolution into all of its courses and does not teach non-scientific concepts based on mythology or literature.
