> The field of biology was created by people who love to classify/name things.

More to the point, the field of biology is so complex that for the longest time we could only name and classify things. Understanding came later, when we'd accummulated enough data and had hints from chemistry and other fields.

The problem is that once we gain that understanding, we add that as one more chapter to our textbooks, one more lesson tacked on, instead of rethinking the curriculum around our understanding.
