Well, OK, just a bit more piling on re: the Grant paper:
The very paper you quoted from indicated that it is continuous traits for which interbreeding is more 'important':
“Introgressive hybridization is effective in increasing genetic variation because it simultaneously affects numerous genetic loci. The total effect on continuously varying traits can be up to two or three orders of magnitude greater than mutation (Grant & Grant 1994).”
Do you know what a continuous trait is?
A continuous trait is one that exists along a continuum - like height. They do not create 'new' traits.
I strongly urge you to learn some basic genetics, re-think your fantasy claims, and re-formulate them as needed.
Hmm, you mean continuously varying traits, just like mutation, except two to three orders of magnitude greater?
If mutation created new information, the link to past traits would be lost and so your claim to continued ancestry would be null and void. Are you now preaching for nullification of past ancestral forms, such has already been done by the overturning of the Tree of life????
If a new trait replaces the old, then that is where the line stops, you can no longer trace back from that point. There would be no linkage to the previous trait, unless it was a continuously varying trait.
Which in reality is exactly what even a mutation is. I'll spell it out slowly so I don't loose you here.
Mutations are copy errors. They take WHAT ALREADY EXISTS and simply vary the existing trait. Nothing new was created. What existed was re-purposed to a new use. Mutations can only change what already exists. It does the exact same thing as mating does, just two to three orders of magnitude less effectively. It varied the existing trait, it did not produce anything new, but only changed the order of what already existed in the way it was written. Just as what occurs during mating, when two separate chromosomes are recombined in a unique way, just at more than one location. In fact the mating is two to three orders of magnitude greater because new genetic information is added from a separate host that did not exist in the other.
Your arguments are null and void, and you refuse to accept the fact that a mutation is a copy error. It simply rearranges what already exists. Nothing new is created in either process. Both do exactly the same thing, one simply to a greater number of loci simultaneously.
