What good is a theory of origin of species that doesn't explain the origin of the first species?
What good is it? Well, it can explain all the others.
And this is in fact what it does. Sheesh, how long have you been posting here and you're still whining and lying about mere definitions rather than any substantive question of fact?
As a working definition for discussion purposes I would be prepared to accept the one Jerry Coyne gives in his book "Why Evolution is True"
Can you quote the preceding sentence, please? I want to see if it says: "The following is the definition of the Theory of Evolution" or whether by some whilom chance it says something completely different.
So both sources appear to agree with what is included in the theory of evolution.
None of those quotations includes the phrase "theory of evolution" and so they cannot conceivably shed any light whatsoever on what the sources think it includes.
