Note 3212 — Chapter XXII · THE FORMS OF HUMAN MARRIAGE
Reading edition
Darwin, ‘The Descent of Man,’ vol. i. p. 334; vol. ii. pp. 394, et seq. Mr. Reade thinks (loc. cit. p. 214) we may infer that Gorillas are polygamous, like stags, cocks, pheasants, and other animals that battle for mates, from the fact that a trustworthy informant had seen two Gorillas fighting. But it is not only polygamous animals that fight for females.
