Darwinism
Darwinism comprises the natural selection concept as advanced by
Charles Robert Darwin in 1859. His theory provided the correct idea to
explain all processes and intricate mechanisms of evolution. The theory of
natural selection is considered on par with Newton’s law of gravitation and
Einstein’s theory of relativity. The monumental work of Darwin was titled as
“The Origin of species” (the original full title of the book was ‘On the Origin of species by means of Natural Selection, or the Preservation of favoured
Races in the struggle for life’).
The book of Darwin convincingly demonstrates the fact of
evolution. Further, it elaborates on the theory of natural selection as a
convincing mechanism for providing evolutionary transformations.
Charles Darwin was born in Shrewsbury, England on February 12,
1809. While studying in college at England through his friendship with
Professor J.S. Henslow, Darwin became familiar with Botany. Later he
accepted the job of a naturalist aboard the ship H.M.S Beagle. The ship was
to spend five years, in exploration around South America (1829 – 34).
During the period of five years, Darwin visited pacific islands and
many parts of the world. He returned to England in 1836. Later he worked
for a further period of 20 years to develop his theory of natural selection.
While Darwin prepared his work for publication, a similar idea to explain
evolution was proposed by another naturalist, Alfred Russel Wallace
(1823-1913) from Malay archipelago. Charles Darwin gracefully accepted
for the publication of his theory as a joint paper with Wallace. Thus the theory
of natural selection is actually titled as ‘Darwin-Wallace theory of
evolution’.
