This is pure, baseless speculation. Again, the fossil record typically (always?) shows creatures entering and leaving the fossil record, over great periods of time, with the same morphology.
False.
Look up the progress of fossilized proto-horses. Loads of demonstrably transitional forms in a well studied line with lots of fossilized remains. The simple fact is that a 8 hand proto-horse is a transitional between a 6 hand proto-horse and a 10 hand proto-horse.
The fossil record shows creatures morphology changing over time. The only creatures whos morphology does'nt change are "optimized" for environments that don't change (e.g. sharks, 'crocs).
It is not baseless speculation, it is based on the fossil record and the well established theory of evolution.
Your namesake did'nt like dishonesty. Willfull ignorence is dishonesty.
"shows creatures entering and leaving the fossil record, over great periods of time, with the same morphology."
I guess the same thing can be said of photographs of me as a kid.
By your standard, there is no proof the kid in the pictures is an adult, since we don't see a photo of him actually growing.
