Most of what Darwin himself proposed is now observed fact.
What you call "a crock" is likely just a creature of your own imagination.
Tell me exactly what Darwin proposed. Not what you think he proposed. It isn’t what you think........................
In the first edition of “On the Origin of Species” in 1859, Charles Darwin speculated about how natural selection could cause a land mammal to turn into a whale. As a hypothetical example, Darwin used North American black bears, which were known to catch insects by swimming in the water with their mouths open:
“I can see no difficulty in a race of bears being rendered, by natural selection, more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale,” he speculated.
The idea didn’t go over very well with the public. Darwin was so embarrassed by the ridicule he received that the swimming-bear passage was removed from later editions of the book.
May I quote from Speciation by Coyne and Orr?
So begins The Origin of Species, whose title and first paragraph imply that Darwin will have much to say about speciation. Yet his magnum opus remains largely silent on the "mystery of mysteries," and the little it does say about this mystery is seen by most modern evolutionists as muddled or wrong.ML/NJ
