The theory of evolution by natural selection is one of the most significant scientific theories. It explains the adaptations found in organisms, the diversity of features and species, and the variation in genes that creates this diversity. With fascinating examples like Darwin's finches, bacteria, and the Tasmanian devil, this program explores the connection between genes, adaptations, survival, natural selection, and evolution.
