The Galpagos Islands were formed by volcanic eruptions in the recent geological past (the oldest of the islands emerged from the ocean just three million years ago), and Darwin realized that the . Critically, Darwin suggested a highly logical alternative mechanism to explain the distribution and types of species, which he termed natural selection. His argument was that if individuals vary with respect to a particular trait and if these variants have a different likelihood of surviving to the next generation, then, in the future, there will be more of those with the variant more likely to survive. San Cristobal was the first island he checked out from September 16th, 1835.
