Biography of Charles Darwin
Introduction
Charles Robert Darwin (1809–1882) was an English naturalist, geologist, and biologist best known for his contributions to the science of evolution. His theory of natural selection revolutionized biology and remains a cornerstone of modern science.
Early Life and Education Charles Darwin
Born: February 12, 1809, in Shrewsbury, England.
Family: Son of Robert Darwin (a wealthy doctor) and Susannah Wedgwood (daughter of the famous potter Josiah Wedgwood).
Education
Studied medicine at the University of Edinburgh (1825–1827) but disliked it.
Transferred to Christ’s College, Cambridge (1828–1831), intending to become a clergyman but developed a passion for natural history.
influenced by botanist John Stevens Henslow and geologist Adam Sedgwick.
Key Observations by Charles Darwin
Galápagos Islands: Noticed variations in finches and tortoises on different islands, suggesting adaptation.
Fossils in South America: Found extinct species resembling living ones, hinting at evolutionary changes.
Geological Formations: Studied coral reefs and earthquakes, supporting Lyell’s uniformitarianism (gradual geological changes).
Development of the Theory of Evolution
After returning, Darwin spent years refining his ideas:
Thomas Malthus’s Essay on the Principle of Population (1798) – competition for limited resources.
Charles Lyell’s =Principles of Geology (1830–1833) – Earth’s gradual changes.
Alfred Russel Wallace – independently conceived natural selection (1858), prompting Darwin to publish.
Natural Selection: Organisms with advantageous traits survive and reproduce, passing on those traits.
Descent with Modification:- Species change over generations from common ancestors.
Struggle for Existence:- Overpopulation leads to competition.
Major Publications by Charles Darwin
1859: On the Origin of Species by Means of Natural Selection – introduced evolution by natural selection.
1871: The Descent of Man, and Selection in Relation to Sex – applied evolution to humans and discussed sexual selection.
Other works: The Expression of the Emotions in Man and Animals
(1872), The Power of Movement in Plants (1880).
Reception and Controversy of Charles Darwin
Supporters: Thomas Huxley ("Darwin’s Bulldog"), Ernst Haeckel, Joseph Hooker.
Opponents: Religious groups (opposed to humans evolving from animals), some scientists favoring Lamarckism or special creation.
Debates: Famous 1860 Oxford evolution debate between Huxley and Bishop Samuel Wilberforce.
Later Life and Death of Charles Darwin
Lived in Down House, Kent, continuing research despite poor health.
Died: April 19, 1882; buried in Westminster Abbey near Isaac Newton.
Legacy
Modern Evolutionary Synthesis: Combined genetics (Mendel) with natural selection.
Impact on Science: Foundation of biology, genetics, paleontology, and anthropology.
Influence Beyond Science: Affected philosophy, ethics, and social sciences.
Criticisms and Modern Views
Early gaps (e.g., lack of genetics understanding) were later filled.
Evolution is now supported by DNA evidence, fossil records, and observed speciation.
Conclusion
Darwin’s work remains fundamental to biology, shaping our understanding of life’s diversity and interconnectedness.
