It's a fine definition, if everyone were to go by it.
Under that definition, changes are small, occur within species, are reversible, and do not result in new species. Therefore there is, or may be, another explanation for the origin of species.
If thats what you're saying and you are not trying to prove Darwinism, we have no disagreement.
I've said several times that I'm arguing against Darwinism, not against the obvious observstion that children are not genetic copies of parents. But you persist in trying to prove what I don't dispute.
I think you get distracted when you start typing and forget the topic. So, take a deep bresth and type one sentence that supports Darwinism. Then roll with that.
