Charles Darwin was a British naturalist and biologist who is famous for his theory of evolution by natural selection. He is also known for his inventions such as the weather vane anemometer, the root-tip microscope, and the worm stone. He was also a prolific writer and a traveler who explored various regions and species of the world.

Early Life and Education

Charles Darwin was born on February 12, 1809, in Shrewsbury, England. His father was Robert Darwin, a wealthy and successful doctor, and his mother was Susannah Wedgwood, the daughter of a famous pottery manufacturer. He had five siblings and was raised in a Unitarian family.

Darwin showed an early interest in nature and science, collecting specimens of plants, animals, and minerals. He also enjoyed reading books on natural history, such as Gilbert White’s ‘The Natural History of Selborne’ and Alexander von Humboldt’s ‘Personal Narrative of Travels to the Equinoctial Regions of America’.

Darwin attended the Shrewsbury School, where he was not a very good student and preferred to spend his time on outdoor activities. He then went to the Edinburgh University to study medicine, but he found it boring and gruesome. He joined the Plinian Society, a student club that discussed natural history and radical ideas. He also learned taxidermy from John Edmonstone, a freed slave who had traveled to South America.

Darwin then transferred to the Cambridge University to study theology, as his father wanted him to become a clergyman. However, he was more interested in botany, geology, and zoology. He befriended several professors and students who shared his passion for science, such as John Stevens Henslow, Adam Sedgwick, and John Herschel. He also read books by William Paley, Charles Lyell, and Thomas Malthus, which influenced his later thinking.


Darwin was an inventive and creative thinker who devised several devices and instruments for observing and measuring natural phenomena. Some of his inventions are:

  • The weather vane anemometer: This was a device that measured the speed and direction of the wind. It consisted of a weather vane that pointed in the direction of the wind and a cup-shaped anemometer that rotated according to the wind speed. The device was attached to a clockwork mechanism that recorded the data on a paper strip. Darwin used this device to study the wind patterns on the Beagle voyage.
  • The root-tip microscope: This was a device that magnified the tips of plant roots to observe their growth and movement. It consisted of a glass tube filled with water that held the root tip in place and a lens that projected its image on a screen. Darwin used this device to study the phenomenon of geotropism, which is the tendency of plant roots to grow downward in response to gravity.
  • The worm stone: This was a device that measured the activity and effects of earthworms on the soil. It consisted of a large stone that was buried in the ground with a metal rod attached to it. The rod protruded above the surface and had markings that indicated the depth of the stone. Darwin used this device to study how earthworms moved the soil and altered its composition over time.

Theory of Evolution

Darwin’s most influential contribution to science and humanity was his theory of evolution by natural selection, which he developed over many years of observation, experimentation, and reflection. According to this theory,

  • All living organisms are descended from common ancestors through a long process of modification and diversification.
  • The diversity and adaptation of organisms are the result of natural selection, which is the differential survival and reproduction of individuals with favorable traits in a given environment.
  • The traits that are selected by natural selection are inherited by the offspring through heredity, which is the transmission of characteristics from parents to offspring.
  • The evidence for evolution can be found in various sources, such as fossils, comparative anatomy, embryology, biogeography, genetics, etc.

Darwin’s theory of evolution was one of the most revolutionary and controversial ideas in history, as it challenged the traditional views of creationism and religion that assumed that all species were fixed and created by God. It also had profound implications for various fields of knowledge, such as biology, anthropology, psychology, sociology, etc.

Darwin published his theory of evolution in his book ‘On the Origin of Species by Means of Natural Selection’ in 1859, after more than 20 years of research and writing. He later expanded his theory in his other books, such as ‘The Descent of Man’ and ‘The Expression of the Emotions in Man and Animals’.


Darwin’s life and works were not well received by his contemporaries or successors. He faced opposition from both religious authorities and scientific rivals who criticized or rejected his ideas. He was also accused of being an atheist or a materialist who denied the existence of God or morality.

Darwin’s reputation declined after his death in 1882, as his theory of evolution was overshadowed by the rise of other scientific theories, such as Mendelian genetics, Lamarckism, and eugenics. His works were also misinterpreted or misused by some groups, such as social Darwinists, racists, and Nazis, who claimed that his theory justified their ideologies and actions.

Darwin’s influence revived during the 20th century, when his theory of evolution was integrated with modern genetics and molecular biology, forming the modern synthesis. His theory was also supported by new discoveries and evidence from various fields of science, such as paleontology, ecology, ethology, etc.

Darwin is now regarded as one of the founders of modern biology and one of the greatest thinkers of all time. He is also admired for his curiosity, courage, and humility in pursuing his quest for truth and understanding.
