Notes on Charles Darwin's Life and Work

Early Life

  • Birth: February 12, 1809, in Shrewsbury, Shropshire, England
  • Family Background:
    • Father: Robert Waring Darwin, a prominent physician known for his size and stature.
    • Mother: Susannah Wedgwood, died when Charles was 8 years old.
    • Grandfather: Erasmus Darwin, a noted scientist who theorized evolution in the poem "The Loves of the Plants" and was a member of the Lunar Society of Birmingham.
  • Education:
    • Early education provided by his sister Caroline and later the Reverend G. Case.
    • Attended Dr. Butler's school in Shrewsbury, later enrolled at the University of Edinburgh at age 16.

University Life

  • University of Edinburgh: 1831-1833, where he became disillusioned with medicine due to poor teaching.
  • Transition to Clergy: Encouraged by father to pursue clergy; enrolled at Christ’s College, Cambridge.
  • Influences: Notable figures included JS Henslow (who arranged Darwin's voyage on the Beagle) and Adam Sedgwick (geologist).

Voyage of the Beagle

  • Departure: December 27, 1831, from Devonport as the ship's resident naturalist.
  • Research Focus: Studied various subjects including meteorology, biology, and geology.
  • Key Observations:
    • Explored the Cape Verde Islands, Brazil, and the Galápagos Islands.
    • Noted species variation, particularly finches, which later contributed to his theory of natural selection.

Development of the Theory of Evolution

  • Natural Selection: Observed variations among species and realized some traits were advantageous for survival.
  • Key Influences: Inspired by Malthus’ work on population control, which helped him finalize his theory of natural selection.
  • Publication: "Origin of Species" published in 1859, presenting evidence for evolution.

Later Life and Publications

  • Continued Research: Conducted extensive studies on various biological and botanical subjects.
  • Major Works: 10 additional publications post-Origin, including work on cross-pollination and sexual selection.
  • The Descent of Man: Explored human evolution and similarities with primates.

Challenges and Criticism

  • Criticism: Encountered opposition from religious figures and scientists like Adam Sedgwick and Richard Owen.
  • Legacy: Widely regarded as the father of modern biology and evolution, influencing scientific and social thought.

Final Years

  • Health Issues: Suffered from chronic illnesses but continued to publish and conduct research.
  • Death: April 19, 1882, buried in Westminster Abbey alongside Isaac Newton.

Conclusion

  • Legacy: Recognized for profound contributions to science and thought, sparking discussions on evolution that continue to this day.
  • Influence of Others: Acknowledgment of Alfred Wallace's contributions alongside Darwin's work.
