On July 28, 1858, the famous Linnaean Society meeting took place in London, where Charles Darwin and Alfred Russel Wallace jointly presented their groundbreaking theory of evolution by natural selection. This event marked a significant milestone in the history of science and forever changed our understanding of the origin and diversity of life on Earth.
Darwin had been working on his theory for nearly two decades, amassing evidence from his travels aboard the HMS Beagle and conducting extensive research on various species. He had already written a substantial portion of his renowned book, "On the Origin of Species," but had been hesitant to publish his findings due to the controversial nature of the topic.
Meanwhile, Alfred Russel Wallace, a young naturalist exploring the Malay Archipelago, had independently arrived at similar conclusions about the mechanism of evolution. In early 1858, Wallace sent Darwin a letter outlining his ideas, which closely mirrored Darwin's own theories.
Realizing the significance of the coincidence, Darwin's friends, geologist Charles Lyell and botanist Joseph Hooker, arranged for a joint presentation of Darwin and Wallace's papers at the Linnaean Society. The meeting was held in the society's headquarters at Burlington House, Piccadilly, London.
The papers presented were titled "On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection." Darwin's contribution consisted of excerpts from an unpublished 1844 essay and a letter he had written to American botanist Asa Gray in 1857. Wallace's paper, "On the Tendency of Varieties to Depart Indefinitely From the Original Type," was read by Lyell.
Interestingly, neither Darwin nor Wallace attended the meeting. Darwin was at home, grieving the loss of his infant son, while Wallace was still in the Malay Archipelago, unaware of the joint presentation.
The reaction to the presentation was initially muted, as the Linnaean Society members did not fully grasp the revolutionary implications of the theory. However, the event spurred Darwin to finalize and publish "On the Origin of Species" the following year, which would go on to become one of the most influential scientific books in history.
The Linnaean Society meeting on July 28, 1858, represents a pivotal moment when the theory of evolution by natural selection was first introduced to the scientific community, setting the stage for a paradigm shift in our understanding of the natural world and our place in it.
