Homologous structures are similar structures in different species that evolved from a common ancestor. They may have different functions, but they share a similar underlying structure. Examples include the forelimbs of different mammalian species, which have different functions such as walking in humans, swimming in whales, and flying in bats, but share a similar bone structure. Analogous structures, on the other hand, are structures with similar functions in different species, but they evolved independently and do not share a common ancestor. Vestigial structures are remnants of structures that were functional in ancestral species but are no longer functional in a particular organism. Embryonic structures refer to structures that are present in the embryo but may disappear or develop into different structures during maturation. Homozygous structures are not a recognized term in biology.
