2 - Geographic Distribution

Distantly Related but Similar

Closely Related but Different

5-Embryology – Theory of Recapitulation

Theory of Recapitulation: developing embryo go through stages resembling their ancestry evolution.

The Theory: Ontogeny Recapitulates PhylogenyA 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

6-Vestigial OrgansAn organ that no longer performs its original function

Top 10:1. Human Appendix2. Male Nipples3. Fake sex in lizards - all female - some act like males4. Sexual organs in dandelions5. Wisdom Teeth6. Blind Fish - isolated population with original in light7. Coccyx - human tail bone8. Erector Pill - muscle for erecting hair9. Hind leg bones of whales10.Wings of flightless birds

Other: hair

7-Biochemistry & Molecular Biology

Same core molecules at work

The chemistry for life is the same or incredibly similar in very dissimilar species
