In 1831, British naturalist Charles Darwin sets out from Plymouth, England, aboard the HMS Beagle on a five-year surveying expe
dition of the southern Atlantic and Pacific oceans. Visiting such diverse places as the Galapagos Islands and New Zealand, Darw
in acquired an intimate knowledge of the flora, fauna, and geology of many lands. This information proved invaluable in the dev
elopment 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, o
rganisms with genetic variations that suit their environment tend to propagate more descendants than organisms of the same spec
ies that lack the variation, thus influencing the overall genetic makeup of the species. Most scientists quickly embraced the t
heory 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 prese
nted 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 develop
ments in genetics and molecular biology led to modifications in accepted evolutionary theory, but Darwin’s ideas remain central
to the field.
