Indeed that is the problem. The understood Darwinian sense of "evolution" tends to have its own place in the dictionary. In the one I'm looking at right now, it's 2a (the theory) and 2b (the historical process) out of a total of five. As I mentioned already, "biological change over time" could refer to the rotting of fruit.
Per "morphology," I could cheat and Google it, but I'm going to guess Goethe, mostly because Y.W. suggests "Young Werther."
Correct! Goethe fancied himself as being something of a scientist, although none of his scientific work carried much merit.
