Darwin joins the Plinian Society in Edinburgh
While at Edinburgh Darwin became a member of a student natural history group called the Plinian Society. He spent time with Robert Grant, a marine biologist and sponge expert. Darwin’s work with Grant is considered to have had an influence on his thinking. It was while at Edinburgh that Darwin wrote his first scientific paper, on bryozoans. -
Darwin Experiment
Darwin conducts experiments to prove that seeds, plants and animals could reach oceanic islands, where they might produce new species in geographic isolation. On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection. -
Natural Selection
Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved". Darwin's process of natural selection has four components: Variation, inheritance, high rate of population growth, differential survival and reproduction.

The Theory of Evolution
Darwin published an explanation of his theory in his best-known work, On the Origin of Species by Means of Natural Selection. In the next century, DNA studies provided scientific evidence for Darwin's theory of evolution. In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.The theory of evolution is based on the idea that all species are related and gradually change over time. -
The Variation of Animals and Plants under Domestication
The Variation of Animals and Plants under Domestication is published. Exploration of the mechanisms of variation, including the principle of use and disuse, the principle of the correlation of parts, and the role of the environment in causing variation, at work in a number of domestic species.
