From the dealer's sale description: "Autograph manuscript signed and titled "Descent of Man" by Darwin, an original leaf from chapter I of The Descent of Man. c. 1870. One page comprising two sheets joined in the process of drafting the work. Blue paper. Headed "Chapt I" and numbered "10." Revisions and corrections in the author's hand. There are a few small differences between this text and the printed edition, for Darwin made additional changes to the work when it was in proofs." An ink finger or thumb print on the verso may be Darwin's.

The text of the draft corresponds to Descent 1: 9-10.



[later insertion in Darwin's hand:] Ch. Darwin.— Descent of Man.

Chapt I

ancient type of structure? It might, also, be naturally enquired whether man, like so many other animals, has given rise either to varieties sub-races, differing but slightly from each other, or to races differing so much, that they may be doubtfully classed as species? How are such races distributed over the world; how when crossed do they react on each other's characters? And so with many other points. The enquirer would next come to the important point, whether man tends to increase at so rapid a rate, as to lead to occasionally severe struggles for existence, consequently to any beneficial variations, whether in body or mind, being occasionally preserved, injurious ones eliminated.
