Note 294 — Chapter III · THEORY OF THE ORIGINAL PAIRING OR MONOGAMOUS FAMILY
Reading edition
Westermarck, op. cit., 20, 24-38, cites the literature. On the pairing seasons among men and animals, see also Hellwald, op. cit., 127 ff.; Kulischer, in ZFE., VIII, 149 ff.; and Mucke, op. cit., 67 ff. The pairing season appears to be the result of natural selection, a device of nature to make sure that the young shall be born at a time most favorable to their sustenance and survival.
