To move lower is entropy confirming creation. To move in the same direction would not be a change, just a descendant. To move higher is evolution.
Entropy refers to changes in the energy content of systems. Changes in the morphology over successive generations of a population are not changes in entropy.
But none of that really address the point I made in my post, which is, you are wrong to attribute your quote to Darwin; he never wrote what you said he did.
