  12. 4-Genetic Evidence Signs and Lines 3 Min. http://www.youtube.com/watch?v=_Ol492CLkdY

  13. 5-Embryology – Theory of Recapitulation Theory of Recapitulation: developing embryo go through stages resembling their ancestry evolution. The Theory: Ontogeny Recapitulates Phylogeny A discredited but famous theory 1866 Real Evidence – similarities in early stages indicates a similar ancestry, that appears briefly, but then continues onward with variation – gills / legs / tails – Hox Genes

  14. 5-Embryology Pig Calf Rabbit Human

  15. 6-Vestigial Organs An organ that no longer performs its original function Top 10: 1. Human Appendix 2. Male Nipples 3. Fake sex in lizards - all female - some act like males 4. Sexual organs in dandelions 5. Wisdom Teeth 6. Blind Fish - isolated population with original in light 7. Coccyx - human tail bone 8. Erector Pill - muscle for erecting hair 9. Hind leg bones of whales 10.Wings of flightless birds Other: hair

  16. 7-Biochemistry & Molecular Biology Same core molecules at work The chemistry for life is the same or incredibly similar in very dissimilar species

  17. 8-Adaptive Radiation

  18. 8-Divergent Evolution

  19. 8-Convergent Evolution

  20. 8-Coevolution
