Re: how populations evolve - when is it "novel"?
The problem is: when gen1 reproduces gen2, will t200 or t500, new traits, will be formed? No!
Wrong. The answer is yes.

Re: Evidence
That doesn't falsify my claim because you are defining a new structure way too broadly. I define new structure as something along the lines of a tonsil. You cannot produce a tonsil from random mutation and natural selection where there was no tonsil before.
OK, then you need to start with an operational definition of a new structure. "Something like a tonsil" isn't any use. You need to supply a set of tests and/or operations that anyone can perform when trying to decide whether or not something is a new structure. Anyone can apply that definition and everyone who does will come the the same conclusion for a particular structure.
Of course, you can't supply such a definition, partly because you don't have a clue and partly because it's just so much easier to dismiss anything we present as "defining a new structure way too broadly".
