Structures that evolved from the same structure in a common ancestor are called homologous structures. This means that the structures have the same underlying structure and organization, even if they have evolved to have different functions in different organisms. This is evidence of common ancestry between different species. Analogous structures, on the other hand, have similar functions but evolved independently in different lineages and do not share a common ancestor. Convergent evolution occurs when similar adaptations arise independently in different lineages due to similar environmental pressures or selective pressures.
