You say
"A real test would be to show that a single-celled organism can evolve into something other than a single-celled organism. Or how about a reptile evolving into a mammal?"
Putting aside the more ludicrous aspects of these as requirements for evidence, would the experimental evidence of fruit flies undergoing mutation leading to the development of a second pair of wings instead of halteres, four winged insects being the ancestral form (obviously in terms of evolutionary theory), be sufficient. I know this isnt as dramatic as the proofs you suggest but it is in the same vein surely? Or all the many homeotic mutations of sepals and petals in plants which produce morphologies resembling other species.
