Prabhupāda: What is that, emancipation?
Hayagrīva: That is to say he simply presented what material he found—that is the fossils. He investigated certain life forms on these island during this trip and theorized about evolution.
Prabhupāda: That is philosophic; that is not scientific. He found something and he based his thesis on that. He cannot find out all the bodies, because there are, at the end, some section, some sect they burn the body. So how he can get information of their body, burned? So his theory is not at all scientific. It is always defective.
Hayagrīva: He spent the rest of his life writing about the material he gathered during this five-year voyage, which is a very short time. And according to his theory of natural selection, the best and the fittest survived. If this is the case, the race will necessarily steadily improve.
Prabhupāda: What does he mean by survive? What is the meaning of his dictionary, "survive"? Nobody survives.
Hayagrīva: Well, by that he means that the strong pass on their hereditary characteristics to their offspring, and that the race..., no individual survives, but that the race improves. But isn't this contradicted by the Vedas? In the present Kali... For instance, Arjuna's physical powers, prowess, was much greater, and that was, what, five thousand years ago. So isn't, instead of improving, instead of the race improving in strength and other qualities, isn't it actually...
Prabhupāda: They are degrading.
