In the first DVD, His Life, medical internist Dr. Tommy Mitchell reveals events and people who helped form Darwin’s faith and science. For example, Darwin considered a career in medicine, then thought about the clergy before becoming a naturalist. Interestingly, during his life-changing voyage on the HMS Beagle, more of his notes related to geology (1,383 pages), than biology (only 368 pages). Belief shared by that the earth formed by gradual processes greatly contributed to Darwin’s views. - Publisher.
