187 A, p. 308. Pearson looks upon' "atavism" merely as mathematically improbable variations. Ibid. , p. 314.
2 Principles of Heredity, p. 87, note.
3 Ibid. , p. 96.
46 SOCIAL DEMOCRACY AND POPULATION [516 MODES OF SELECTION According to the usage given the term selection in this essay, any influence which, without causing the appearance of new variations, tends to produce a change in the heredi- tary quahties of a population from generation to genera- tion, is a selective influence. The term, t...herefore, includes more than natural selection in the Darwinian sense. Dar- win, as has been noted, applied the term natural selection to the process by which the elimination of a certain strain was produced by a death-rate greater than the reproductive rate of that strain. It is evident, however, that a change in the amount of an hereditary characteristic in a popula- tion can be produced by differing birth-rates in differing stocks, even though there is no tendency whatever for any stock to be eliminated.
