Evolutionary Thinking Quotes
This quotation from this letter was one of the key items of evidence showing that Wallace had independently developed the concept of Evolution before Darwin published his famous treatise. Darwin began formulating his theory of natural selection in the late 1830s but he went on working quietly on it for twenty years. He wanted to amass a wealth of evidence before publicly presenting his idea. During those years he corresponded briefly with Wallace (right), who was exploring the wildlife of South America and Asia. Wallace supplied Darwin with birds for his studies and decided to seek Darwin's help in publishing his own ideas on evolution. He sent Darwin his theory in 1858, which, to Darwin's shock, nearly replicated Darwin's own…. Joseph Dalton Hooker arranged for both Darwin's and Wallace's theories to be presented to a meeting of the Linnaean Society in 1858. However, Wallace seems to have been onto the idea of evolution over a decade before as this quotation shows.
