Note 17 — DIVISION III. § 2. CHAPTER V. 12-21.

See E. B. Tylor in Encycl. Brit. ii, s.v. ANTHROPOLOGY, p. 114: 'The polygenist view (i.e. the doctrine of a plurality of origins) till a few years since was gaining ground. Two modern views, however (i.e. the belief in the antiquity of man and the development of species), have tended to restore, though under a new aspect, the doctrine of a single human stock.' Cf. Darwin, Descent of Man (2nd ed.), p. 176: 'Those naturalists who admit the principle of evolution ... will feel no doubt that all the races of men are descended from a single primitive stock.'
