Evolution+In+Process


 * ​Evidence in Evolution**

__ Homologous __--Similar features that came from a shared ancestor
 * Differenet animals can have similarities in bone structure

__ Analogous __--Similar functions and look alike.
 * Different embryological development.
 * For example, bird's wings develop independently through recent ancestors.

__ Vestigal Structure: __ A functionless structure that was once functionable
 * For example. human tailbones and appendix.
 * Some functionless structures may be an important function in another organism.
 * Whales have a gene that stays unchanged, or conserved, such as the gene to make hind legs.



__Similarities in Embryology__
 * 1) When an animal is an embryo, they can look similiar to another organism.
 * 2) For example a gorrilla can look like a fish.



__Similarities in Macromolecules__
 * 1) Similar structure of organisms have a more recent ancestor
 * 2) Molecules of different species are similar but not identical
 * 3) Differ in amino acids
