The two theories, one biological, the other political, both had their genesis many years before they became popular, under the skillful stewardship of their respective pedagogues. In the case of Darwin, the groundwork was laid by his own grandfather, among a few others. Erasmus Darwin expressed his biological evolutionary ideas in the context of his study of plants. A man of genius but not probity, Darwin forwarded the ideas of Charles Linaeus, an earlier scientist who announced that man was just another animal, and speculated about evolution of species. Erasmus’s grandson, Charles Darwin, after a five-year expedition to the Galápagos Islands as a “naturalist,” wrote the book that launched the ideas of “survival of the fittest” and that new species emerge from the natural struggle for survival. In order for those changes to take place required millions of years, thus the automatic rejection of the Genesis account as “scientifically viable.” Natural selection was his explanation of the internal natural mechanism for evolutionary change, thus no appeal to supernatural creation was necessary.
