Darwin's theory of evolution is based on the idea that organisms with favorable variations survive , reproduce and pass these variations on is called:
homologous structures
similarities in the environment in which they live
natural selection
Populations that have advantageous characteristics will increase in number
analogous structures
comparative embryology
species
a large population of flies

similarities in the environment in which they live
natural selection
Populations that have advantageous characteristics will increase in number
analogous structures
comparative embryology
species
