Document Summary

Historical special creation: thought the all species: created independently, do not change over time, created recently, at the same time. However, observations suggested otherwise: species change over time, extinction, time-series of species appearance, environments had changed over time (places that are now mountains, use to by underwater, relatedness of species si(cid:373)ilarity (cid:449)ithi(cid:374) di(cid:448)ersity (cid:862)tree of life(cid:863) Early definition evolution: the development of new types of living organisms form pre-existing types.

Darwin is the parent of modern evolutionary theory because: provided evidence that evolution had occurred, proposed natural selection mechanism of evolution, could explain adaptation, provided evidence that evolution would occur by natural selection.
