This is a nicely done lecture on design flaws in our anatomy and physiology, to refute claims of intelligent design.
I know exactly how creationists will reply, though, since I’ve heard it often enough. She’s making a theological argument, they’ll say, claiming to know God’s intent and making an assumption of his goals. It will be a restatement of the old chestnut, “God works in mysterious ways.”
However, that’s not the argument here. Imperfections and sub-optimal properties are an outcome of evolutionary theory; this is a positive argument that observations of the world best fit a model positing a history of accidents and refinements constrained along lines of descent. If the creationists want to complain, they first have to propose a set of predictions that would discriminate between accident and design, and starting from a god who can do anything at any whim is not a fruitful source of hypotheses.
