The divergence of our understanding begins here. If I say that you are descended from your grandfather, it's true that there is an intermediate generation to be identified. I don't see how this requires "a quantization of the continuum to asset." We don't disagree that individuals are quantifiable. It's the chain of common descent that makes up the continuum. True, each generation is made up of individuals. That's not a contradiction, or an invocation of the fallacy.
So the theory of such a continuum is an interpretation of evidence which has been quantized by fossils along the geologic way. Which is why I said this:
It cuts both ways.
