T.R. Gregory Evolution flies. According to Hogg, a physicist, the empirical support for evolution is limited to a few experiments on fruit flies and is altogether lacking in predictive tests and falsifiable hypotheses. Evolution is no different in this regard from, say, the theory of relativity.
Gravity is a scientific fact that relativity seeks to explain.
That organisms share a common evolutionary history is as much an established fact as any other in science, and the theory of evolution seeks to elucidate the mechanism or mechanisms by which this has occurred. The results of countless laboratory and field experiments strongly suggest that it does. The past 150 years of biology cannot be ignored.
