Presentation Transcript

  1. Chapter 15Section 3

  2. Evidence of Evolution • found in the fossil record • the geographical distribution of living species • homologous structures of living organisms • similarities in early development or embryology.

  3. Natural Selection • Acts directly on the genes (test question) • The struggle for existence means that members of each species compete regularly to obtain food, living space, and other necessities of life.

  4. Fossils include(test question) • Eggs • Footprints • Body parts

  5. Most fossils form in sedimentary rocktest question) • (

  6. vestigial organs(test question) • The organs of many animals are so reduced in size that they are just vestiges, or traces, of homologous organs in other species • vestigial organs may resemble miniature legs, tails, or other structures.

  7. Similarities in Embryology

  8. Homologous body structures
