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. In 1831, he embarked on a five-year voyage on the HMS Beagle after managing to persuade Captain Robert FitzRoy to let him join him as the ship's naturalist.

When this project failed, Cobos moved to El Progreso, a settlement on San Cristbal, and focused his efforts on the production of sugar cane, coffee, and tortoise oil.
