this is your belief. its a fact that those are fins. not legs.
They are limbs. Did you even read the posts and see the illustrations?
Did you perhaps not understand it?
Simplisticly put, it means that for every bone in a whale's "fin", you can find an analogous bone in the same place of any random land walking mammal - and the same genes in both are responsible for those structures. Millions of years of evolution off course has changed the shape of those bones, quite drastically even, and some even mutated away completely. But the basic structure of the ones that remain, how they connect to one another, is virtually the same among all mammals.
This
match of bones is not present in fins.
You should read the articles you link, because this one doesn't support your case. It actually supports the opposite (no surprise there).
It is talking about the
ancestral genes of the genes that make limbs in tetrapods.
The genes they
evolved from.
As in, those ancestral genes
did not produce limbs.
One branch of off spring became the limb making genes present in mammals.
The other branch is found in sharks, among others. That branch does not make limbs.
Exactly like what the barbarian has been explaining you with the patience of an angel, that I don't even believe exists.
i can say its a vestigial legs. so we may not find all the internal structure of a real legs
Evolution says: you will find exactly zero internal structure of real legs. In any of them.
