Wallace, Darwin, and the theory of natural selection

Abstract

On 1 July 1908 the Linnean Society of London commemorated the reading before the Society fifty years earlier of the DarwinWallace joint papers, "On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection." 1 On the first occasion only some thirty Fellows and guests had been present at a quiet, unheralded meeting; the authors themselves were absent. Now there was a large and distinguished gathering celebrating the historic event. Two of the original cast were present, the naturalist Alfred Russel Wallace (1823-1913) and the botanist Sir Joseph Dalton Hooker (1817-1911). The other two, the biologist Charles Robert Darwin (1809-1882) and the geologist Sir Charles Lyell (1797-1875) had been dead for many years. Hooker, now a venerable nonagenarian, spoke of his "halfcentury-old real or fancied memories" of that June in 1858 when his old friend Darwin received Wallace's paper on natural selection. He based his account on Sir Francis Darwin's Life and Letters of Charles Darwin, remarking with some uneasiness that, beyond the letters from Darwin to himself and to Lyell, no other documentary evidence existed of the events of those turbulent weeks before the reading of the papers. Despite a search, the letters to Darwin from Hooker and Lyell could not be found, "and, most surprising of all, Mr. Wallace's letter and its enclosure have disappeared." 2
