Charles Darwin, widely considered as one of
the greatest and most revolutionizing scientists
in history, was the British naturalist who
formulated the theory of evolution. Pre-Darwin,
it was thought that each species of life on
earth came individually and that none had
ever changed its form. He confuted this notion
and demonstrated from his research that
evolution is the law of nature and all living
things on earth have descended from common
ancestors who lived millions of years ago. He
proved that animals and plants have evolved
in an orderly manner and keep on evolving
even today.
Early Life:
Born at Shrewsbury in 1809, Darwin was
raised by his eldest sister from the tender age
of eight. Young Darwin had a passion for
gathering up even insects and minerals and he
used to experiment with them. When Darwin
was 16, he joined Edinburg University to study
medicine. However, he was too gentle and
tender to become a proper physician.
Anatomy, in particular, sickened him. He hated
the surgical operations, because they had to
be performed without any anesthetics at that
time. This made Darwin a great failure as a
medical student.
Darwin said goodbye to Edinburg in 1828 and
sought admission in Cambridge to study
Theology. There, he also disregarded his
studies and was more interested in beetles
than theology. He was lucky to attain his
degree anyhow. At Cambridge, he managed to
make valuable friends, even befriending the
professors of botany and geology.
Contributions and
Achievements:
Darwin got his big break in 1831. A naturalist
was needed to travel along on a scientific
expedition – a voyage around the world in the
brigantine HMBS Beagle under the supervision
of Captain Fits Roy. Luckily, some of his
Cambridge fellows also recommended him for
the place. The voyage took around five years.
Throughout this voyage, Darwin collected
bones of extinct animals. He was curious
about the relationship between the extinct
animals and the existing ones. The unusual
marine iguana, the tortoises and the finches
on the Galapagos Islands in the pacific made
him perplexed, since similar, yet rather
distinct, forms of the same animals were found
on separate islands. These observations led to
his legendary ideas on evolution.
After the return, Darwin moved to London for a
while and compiled an account of his travels.
Darwin got married to his cousin Emma
Wedgowood in 1839. The coupled moved to
Downe House in Kent in 1844. There, Darwin
got a letter from the naturalist Alfred Russel
Wallace, who had made similar observations
about evolution separately. A collaborative
report by Darwin and Wallace was published
in 1858. Darwin publicized the theory of
evolution in his famous book, “The Origin of
Species by Natural Selection”, in 1859. The
book, which asserted that all the varied forms
of life on earth could, in the course of time,
have evolved from a common ancestry, was a
huge success. Darwin also commented that in
the struggle for life, only the ‘fittest’ creatures
would survive while others fail.
The book became controversial due to its
conflict with the religious belief about the
creation of the world. However, in later years,
it was embraced by all biologists. Darwin’s
another book, “The Variation of Animals and
Plants Under Domestication”, came out in
1868. It is considered to be his second most
significant work. The book maintains that man,
by selective breeding, could make rather
different breeds of pigeons, dogs, and some
species of plants also. His work also included
“The Various Contrivances by which Orchids
are Fertilised by Insects”, “Insectivorous
Plants”, “The Power of Movement in Plants”,
“Descent of Man”, and “The Formation of
Vegetable Mould Through the Action of
Worms”.
Later Life and Death:
Charles Darwin died at 74 and he was buried
in Westminster Abbey, fairly near to the tomb
of Sir Issac Newton. Out of his 10 children, of
whom seven survived him, four became
prominent scientists. Three of his sons went
on to become fellows of the Royal Society, just
like their legendary father.
