context_page_description: Georges-Louis Leclerc, Comte de Buffon was a French naturalist, mathematician, cosmologist, and encyclopédiste.
  His works influenced the next two generations of naturalists, including Jean-Baptiste Lamarck and Georges Cuvier. Buffon published thirty-six quarto volumes of his Histoire Naturelle during his lifetime; with additional volumes based on his notes and further research being published in the two decades following his death.
  Ernst Mayr wrote that "Truly, Buffon was the father of all thought in natural history in the second half of the 18th century".
  Buffon held the position of intendant at the Jardin du Roi, now called the Jardin des Plantes.
context_section_description: Buffon's Histoire naturelle, générale et particulière (1749–1788: in 36 volumes; an additional volume based on his notes appeared in 1789) was originally intended to cover all three "kingdoms" of nature but the Histoire naturelle ended up being limited to the animal and mineral kingdoms, and the animals covered were only the birds and quadrupeds. "Written in a brilliant style, this work was read ... by every educated person in Europe". Those who assisted him in the production of this great work included Louis-Jean-Marie Daubenton, Philibert Guéneau de Montbeillard, and Gabriel-Léopold Bexon, along with numerous artists. Buffon's Histoire naturelle was translated into many different languages, making him one of the most widely read authors of the day, a rival to Montesquieu, Rousseau, and Voltaire.
  In the opening volumes of the Histoire naturelle Buffon questioned the usefulness of mathematics, criticized Carl Linnaeus's taxonomical approach to natural history, outlined a history of the Earth with little relation to the Biblical account, and proposed a theory of reproduction that ran counter to the prevailing theory of pre-existence. The early volumes were condemned by the Faculty of Theology at the Sorbonne. Buffon published a retraction, but he continued publishing the offending volumes without any change.
  In the course of his examination of the animal world, Buffon noted that despite similar environments, different regions have distinct plants and animals, a concept later known as Buffon's Law. This is considered to be the first principle of biogeography. He made the suggestion that species may have both "improved" and "degenerated" after dispersing from a center of creation. In volume 14 he argued that all the world's quadrupeds had developed from an original set of just thirty-eight quadrupeds. On this basis, he is sometimes considered a "transformist" and a precursor of Darwin. He also asserted that climate change may have facilitated the worldwide spread of species from their centers of origin. Still, interpreting his ideas on the subject is not simple, for he returned to topics many times in the course of his work.
  Buffon considered the similarities between humans and apes, but ultimately rejected the possibility of a common descent. He debated with James Burnett, Lord Monboddo on the relationship of the primates to man, Monboddo insisting, against Buffon, on a close relationship.
  At one point, Buffon propounded a theory that nature in the New World was inferior to that of Eurasia. He argued that the Americas were lacking in large and powerful creatures, and that even the people were less virile than their European counterparts. He ascribed this inferiority to the marsh odors and dense forests of the American continent. These remarks so incensed Thomas Jefferson that he dispatched twenty soldiers to the New Hampshire woods to find a bull moose for Buffon as proof of the "stature and majesty of American quadrupeds".
  In Les époques de la nature (1778) Buffon discussed the origins of the solar system, speculating that the planets had been created by a comet's collision with the sun. He also suggested that the Earth originated much earlier than 4004 BC, the date determined by Archbishop James Ussher. Basing his figures on the cooling rate of iron tested at his Laboratory the Petit Fontenet at Montbard, he calculated that the age of the earth was 75,000 years. Once again, his ideas were condemned by the Sorbonne, and once again he issued a retraction to avoid further problems.
