Note 289 — Chapter IV
Reading edition
“Nowhere can lines of demarcation be so clearly drawn, so imperceptibly do the families of mankind blend at their circumferences. The various classifications which have been attempted are so many proofs of unity of origin; and their confliction shows the fallacy of the theory of diversity. * * * * We cannot admit that mankind can have diversity of origin while so united by one great plan. If a species or variety of the genus homo sprang up in Europe and another in America by agency of conditions existing in those localities, it would be beyond probability that they should both be formed on the same plan.”—H. Tuttle’s Origin and Antiquity of Physical Man Scientifically Considered, pp. 34–5. Boston, 1866, 12mo.
