What are the 4 theories that support evolution?

Evolution may refer to both the observed phenomenon and the theoretical framework explaining observations in terms of what we know of that phenomenon. Phenomena need no support, just verification. Theories aren't usually supported by other theories, but by observational data. Just so for evolutionary theory: it's supported by the observations in embryology, genetics, comparative genomics, palaeontology, ethology, zoology, microbiology, molecular Biology, and so forth.
