While this episode is one of my favorites, one thing is particularly laughable: it is supposed to be about evolution, yet even Prof. Mathers do not seem to know the difference between an ape and a monkey. He repeatedly calls what seems to be a chimpanzee a "monkey." At one point, when Cathy asks him why the chimpanzee did not further evolve, he explains that this type of "monkey" did not evolve into man, bespeaking another confusion--that we evolved from apes rather than that we had a common ancestor. How much the writer should have known about such matters in 1963 is an interesting question...
