I adore strange dated genre literature. Um. Except when it's THAT egregious.
I had a bit of free association regarding moth colors which I will share for your amusement. There is a famous (possibly apocryphal) case of speedy natural selection in which a type of moth which naturally occurs in white (common) and black (rare) colors suddenly had the frequency of colors switch. It turned out that the moths perch on birch trees, which have white bark. Black moths were quickly spotted and eaten by birds, often before they could pass on the black gene. But then a factory started spewing pollution, coloring the white trees black. Suddenly the white moths were getting gobbled up, and the black moths survived to propagate.
