Famed British biologist Charles Darwin died 135 years ago on April 19. Often dubbed as the “Father of Evolution,” Darwin provided the world with explanations on the origin and evolution of living things on Earth.

Darwin was born on Feb. 12, 1809, in Shrewsbury, England, and was homeschooled with his sister Caroline until the age of 8. He was sent to a boarding school after spending a year at a day school. His father enrolled him to the University of Edinburgh to study medicine. There, he began collecting, hunting, and naturalizing rather than studying medicine, according to Charles Darwin Online.

After graduating in 1831, Darwin accepted a job on the HMS Beagle, a vessel that mapped South America’s coast over a span of two or three years. During the job, he took notes and sent samples and specimens to botanist John Henslow in England. After returning to England after five years on the vessel, Darwin found that his specimen collection amazed Henslow and geologists, zoologists, and botanists.

Darwin’s research during his job on HMS Beagle contributed to the development of theory of evolution and natural selection. He, however, took over 20 years to publish the revolutionary theory — in 1858. He was apparently concerned about the acceptance of his idea. However, the theory turned out to be groundbreaking and was eventually widely accepted in mainstream science.

Check out some of Darwin’s famous quotes gathered from BrainyQuote and Charles Darwin Online.

  • “The mystery of the beginning of all things is insoluble by us; and I for one must be content to remain an agnostic.”
  • “We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.”
  • “False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for every one takes a salutary pleasure in proving their falseness.”
  • “At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate, and replace the savage races throughout the world.”

  • “It is a cursed evil to any man to become as absorbed in any subject as I am in mine.”
  • “A man's friendships are one of the best measures of his worth.”
  • “A scientific man ought to have no wishes, no affections, - a mere heart of stone."
  • “False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for every one takes a salutary pleasure in proving their falseness.”
