🧬 Darwin Day — and the Evolution of Ideas

---

But like evolution itself, scientific understanding does not appear in a single leap.
It grows gradually. It builds on earlier forms. It adapts. It refines.

Just as species evolve over time, knowledge evolves too.

Darwin’s theory of natural selection was revolutionary — but it was not created in isolation. It was part of a much longer intellectual journey shaped by many thinkers before him and alongside him.

• Erasmus Darwin (1731–1802)
  Early ideas about species change and common ancestry.

• Jean-Baptiste Lamarck (1744–1829)
  One of the first to propose a formal theory of evolution.

• Georges-Louis Leclerc, Comte de Buffon (1707–1788)
  Suggested that species might change over time.

• Étienne Geoffroy Saint-Hilaire (1772–1844)
  Proposed structural unity among animals.

• Georges Cuvier (1769–1832)
  Founder of paleontology; demonstrated extinction.

• James Hutton (1726–1797)
  Introduced the concept of “deep time.”

• Charles Lyell (1797–1875)
  Developed uniformitarian geology — crucial for Darwin’s thinking.

• William Smith (1769–1839)
  Pioneer of stratigraphy and fossil succession.

• Carl Linnaeus (1707–1778)
  Created the modern classification system.

• Thomas Robert Malthus (1766–1834)
  His work on population pressure influenced Darwin’s idea of natural selection.

• Robert Chambers (1802–1871)
  Published Vestiges of the Natural History of Creation (1844), preparing public debate on evolution.

• Alfred Russel Wallace (1823–1913)
  Independently conceived natural selection; their findings were presented jointly in 1858.

• Joseph Dalton Hooker (1817–1911)
  Botanist and close collaborator of Darwin.

• Richard Owen (1804–1892)
  Developed the concept of homology in comparative anatomy.
  https://en.wikipedia.org/wiki/Richard_Owen
   
• Gregor Mendel (1822–1884)
  Discovered the laws of inheritance — later essential to evolutionary biology.
  https://en.wikipedia.org/wiki/Gregor_Mendel
   

Darwin explained how natural selection works.
The 20th century explained how inheritance makes it possible.

• Ronald Aylmer Fisher (1890–1962)
  One of the founders of population genetics.
  In 1918 he mathematically reconciled Mendelian inheritance with natural selection, and in The Genetical Theory of Natural Selection (1930) he gave evolution a rigorous statistical foundation.
  https://en.wikipedia.org/wiki/Ronald_Fisher
   
• Theodosius Dobzhansky (1900–1975)
  A central architect of the Modern Synthesis.
  His book Genetics and the Origin of Species (1937) demonstrated that evolution could be observed and measured in real populations.
  https://en.wikipedia.org/wiki/Theodosius_Dobzhansky
   
• Ernst Mayr (1904–2005)
  Developed the biological species concept and clarified mechanisms of speciation.
  His work integrated systematics, geography, and evolutionary theory into a unified framework.

Together, they transformed Darwin’s 19th-century insight into the comprehensive evolutionary biology we recognize today.

It is about the long, collective journey of human curiosity.

Just as species evolve through countless generations,
ideas evolve through countless minds.

Science is not a monument.
It is a living process.

Darwin didn’t work alone — he connected centuries of curiosity into a powerful framework in On the Origin of Species (1859).

And evolution — both biological and intellectual — continues today.

And that may be the most evolutionary idea of all.
