It was on this day in 1858 that joint papers about the theory of evolution, written by Charles Darwin and Alfred Russel Wallace, were presented to the Linnean Society of London.
Wallace was only 25 at the time that the papers were read, and Darwin was 49. Darwin had begun formulating his theories about natural selection about 20 years earlier, but he was a slow, methodical worker, and he thought that since no one else had the same ideas, he might as well take his time.
Young Alfred Russel Wallace, on the other hand, had no such hesitations. He'd done his fieldwork in Malaysia and Indonesia, studying animals there, based in good part on geology. He came up separately with the idea of natural selection as the mechanism of evolution. When Darwin found out about it, he was shocked, so he rushed to get his ideas into print.
The truth is that neither man dreamed up his theory of evolution out of nowhere. For many years, scientists had known that evolution existed — that species were created and became extinct over time. The problem was, they didn't know why.
Neither Darwin nor Wallace was present to read his own paper on this day in 1858. Wallace was still in Malaysia, and Darwin was mourning the death of his young son Charles. The meeting itself was long and boring, with an announcement of donations and gifts to the society, then a new member of the council was elected, and a long tribute was delivered in memory of a member who had recently died. Then the presentation of papers began, first an excerpt from Darwin's On the Origin of Species, then a letter from Darwin, then Wallace's paper, "On the Tendency of Varieties to Depart Indefinitely from the Original Type." After that, there were five more papers presented — other topics included "The Vegetation of Angola" and "Hanburia, a new genus of Cucurbitaceae." The meeting took several hours, and most of the gentlemen who heard the papers were so lethargic from all the information thrown their way that they didn't realize that anything out of the ordinary had happened. So even though this is the day that one of the most revolutionary ideas in science was delivered to the public, it barely made a wave.
Darwin's On the Origin of Species was published a year later.
