Document Summary
Two hypotheses: divine creation, god created organisms exactly as we see them today by a miracle, species do not change, they are fixed , creation occurred in the recent past (6,000 years ago) Divine creation (cont. : prevailing paradigm for 2,000+ years, consistent with the view that miracles occur and god intervenes in daily affairs, its usefulness began to fail about 400 years ago. This was a good hypothesis because it was simple, and it stimulated research into exploring god"s creations. It was not a good hypothesis because it depends upon supernatural explanations (miracles) and it can not be adequately tested (anything is possible with a god) Lamarack proposed: evolution by acquired characteristics : 50 years later charles darwin published: the origin of species (1859) claiming evolution occurred by natural selection. This changed him from an ordinary creationist to an extraordinary evolutionist.
