Presentation transcript:

Evidence of Evolution

 Preserved or mineralized remains or imprint of an organism  Found in sedimentary rock  Shows, what some to believe are, intermediates between current species

Archaeopteryx

 Vestigal Structures ◦ Structures with little or no know use  Appendix, whale pelvis, eyes in blind cave salamanders

 Homologous Structures ◦ Similar design in structures that now have different functions

Embryology

 Proteins such as hemoglobin are similar in closer related species  DNA is closely related to protein production, thus in species with a common ancestor share more DNA similarity  DNA similarities parallel the proposed ancestry based on anatomy and the fossil record

 Through artificial selection we have created organisms that look and act differently than distant ancestors ◦ Dogs ◦ Cats ◦ Cattle  If we can do it artificially could it happen naturally?
