Desirable ANS signed “C. Darwin,” one page on a 4.75 x 3 postcard, postmarked October 27, 1872. Written from his Down House in Beckenham, Kent, a brief note to fellow naturalist Alfred Russel Wallace, in full: "Can you tell me Mr. Fr. Geach’s address? I want to send him my book—." Darwin adds the address on the reverse in his own hand. In fine condition.
In 1858, both Darwin and Wallace, through their own separate research, independently conceived the theory of evolution through natural selection. While essentially similar, their views on evolution did bear its differences: Darwin emphasized competition between individuals of the same species to survive and reproduce, whereas Wallace highlighted environmental pressures on varieties and species that forced them to adapt to their local conditions, which led populations in different locations to diverge. The men published the concept in a joint presentation of papers in 1858 entitled 'On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection.' A rare and interesting association from the foremost minds of evolutionary theory.
