Instead of me saying not hey haven't and yo saying yes they have , give me one specific example.
For the umpteenth time: Greenish Warblers
Plus, for the third time, Abert's squirrel.
Sub populations are the same species.
Yes, until they are not. Decide now. Are you equating "kind" with "species" or with "clade"?
Not true. All anyone has sid is that it happened. There is always a variety of traits but they NEVER result in evolution. No mutation has ever produced a lifeform that was not the same as its parents. Hair color, skin color etc are the result of dominant and recessive genes and mutation are not necessary for them to change in the offspring.
"Never"? "No mutation has ever...."? Pretty strong statements. Do you have the research to back that up?
Science is inductive, not deductive. It does not pretend to have discovered everything. If you asked a naturalist in 1600 whether there were any black swans, he would say no, but he would not say that they could "never" be discovered. In fact, they were. They are Australian
Neither you or anyone else has provided the biological evidence of HOW, natural selection chooses traits.
We have, or at least, we have presented evidence we believe shows it. If it is not the kind of evidence you want, you have to tell us what the kind of evidence you want looks like.
Traits are preprogramed by the genes. If a gene is dominant, the kid will het the traint. If it is recessive, he will not.
Have you decided that you no longer believe that mutation is real? What you are describing is true (or would be if stated more clearly) when the genes are inherited without mutation. Even with mutation, it is mostly true, but the allele or gene the offspring inherits is on that in the parent is only in the seminal cell. All of the parent's other cells are unmutated. The grandparent did not have it, and the parent did not inherit it.
How does naturel selection, even if it is true, cause an A to become a B? Explain the biology that makes it possible.
An A does not become
a B. No one who knows anything about evolution believes that. I even stated so at the begining of the post in which I explained how breeding and Natural Selection work.In that post, you accept that over time, with controlled breeding a pack of dogs can become a pack of foxhounds, or bloodhounds, or a pack of collies or shepherds. You also accept that nature can shape this breeding or at least you seemed to.
So what scientific reasoning can you give me for claiming that with even more time, more separation from other breeds, more specialization two different breeds can never become so separate as to become separate species. And then explain
exactly why the Eastern and Western breeds of the Greenish Warbler are, in your opinion,
not separate species. They cannot breed with one another and in time they will only continue to become less and less similar.
