This paper entitled "What Darwin Didn't Know" states that Charles Darwin (1809-1882), a naturalist, had a great vision of evolution when he made a 5-year naturalist trip to South America and saw signs that plants and animal species were not fixed and permanent. It wasn't until twenty years after his trip, in the year 1859 that he published a book titled, "On The Origin Of Species" that detailed his theory on evolution. He however knew that much more research needed to be conducted. Darwin's work has had significant scientific relevance for more than 150 years. His theory on evolution basically stated that, "all life is related, species change over time in response to natural selection and new forms replace those that come before." Evolution is believed by many to be the way that biology works, and it is seen as the central organizing principle of life on earth. Darwin's theory encompassed di scoveries made in geology, like the constant motion of continent, and in genetics, when the first fossilized ancient human called the "Neanderthal Man" was discovered. The paper under review discusses Darwin's biography, his research, his theory, and what he didn't know.
