"embraced... evolution as fact". So ends all science. The scientific method requires theories to be thought fallible and up to criticisms, corrections and improvements. To suggest that Evolution, including all of its presumptions, is not open to considerable criticism rubs against my arm hair and is the stuff in my appendix.
The unscientific need to circle up the wagons around Evolution is harming our academic nature.
And "No," I do not need to propose an alternative theory for the above to be true.
