A 1 de julho de 1858 (faz hoje 159 anos) Charles Darwin e Alfred Russel Wallace apresentaram, pela 1ª vez, diante de um grupo de naturalistas, na Linnean Society of London, a teoria da evolução. Uma mudança de paradigma, trazida no paper “On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection. By CHARLES DARWIN, Esq., F.R.S., F.L.S., & F.G.S., and ALFRED WALLACE, Esq. Communicated by Sir CHARLES LYELL, F.R.S., F.L.S., and J. D. HOOKER, Esq., M.D., V.P.R.S., F.L.S, &c.”
Sobre a Tendência das Espécies em Formar Variedades e a Perpetuação das Variedades e Espécies por Meios Naturais de Seleção, foi o primeiro anúncio da teoria de Darwin-Wallace da evolução pela seleção natural, que seria impressa pela primeira vez no dia 20 de agosto. A apresentação estimulou Darwin a escrever um “abstrat” do seu livro, um resumo publicado em novembro de 1859, como A Origem das Espécies.
“The theory of evolution by natural selection was first proposed by Charles Darwin and Alfred Russel Wallace in the scientific article below. It is probably the most important scientific paper in the history of biology and it was first read at a meeting of the Linnean Society of London on July 1st 1858, before being published on the 20th August of that year in the Journal of the Proceedings of the Linnean Society: Zoology. Wallace’s essay on natural selection, which forms part of the article below, was written in the village of Dodinga on the Indonesian island of Halmahera (Gilolo) in February 1858 and posted to Darwin together with a covering letter from the neighbouring island of Ternate probably in March 1858. It’s unexpected arrival at Darwin’s home in Kent in June 1858 spurred a shocked Darwin to hastily write his famous book On the Origin of Species, which was published fifteen months later in November 1859.” (aqui)
