  • Analogy vs Homology

    Analogy, or analogous structures, is actually the one that does not indicate there is a recent common ancestor between two organisms Even though the anatomical structures being studied look similar and maybe even perform the same functions, they are actually a product of convergent evolutionJust because they look and act alike does not mean they are related closely on the tree of life.
