This sent me on an evolutionary thought tangent -- once upon a time, being able to see in the dark would have been such a huge evolutionary advantage that it might have propagated pretty quickly (might, depending on the vagaries of the gene pool); now, however, it's worthless for survival in a large part of the world. I wonder what other traits have surfaced and faded in a similar manner.
