British naturalist Charles Darwin sets out from Plymouth, England,
aboard the HMS Beagle on a five-year surveying expedition of the
southern Atlantic and Pacific oceans. Visiting such diverse places as
the Galapagos Islands and New Zealand, Darwin acquired an intimate
knowledge of the flora, fauna, and geology of many lands. This
information proved invaluable in the development of his theory of
evolution, first put forth in his groundbreaking scientific work of
1859, On the Origin of Species by Means of Natural Selection.
Darwin’s theory argued that organisms gradually evolve through a process
he called “natural selection.ö In natural selection, organisms with
genetic variations that suit their environment tend to propagate more
descendants than organisms of the same species that lack the variation,
thus influencing the overall genetic makeup of the species. Most
scientists quickly embraced the theory that solved so many puzzles of
biological science, but orthodox Christians condemned the work as
heresy. Controversy over Darwin’s ideas deepened with the publication of
The Descent of Man, and Selection in Relation to Sex (1871), in which he
presented evidence of man’s evolution from apes.
By the time of Darwin’s death in 1882, his theory of evolution had
become generally accepted. In honor of his scientific work, he was
buried in Westminster Abbey beside kings, queens, and other illustrious
figures from British history. Subsequent developments in genetics and
molecular biology led to modifications in accepted evolutionary theory,
but Darwin’s ideas remain central to the field.
