Georges-Louis Leclerc, Philosopher de Buffon (7 September 1707 – 16 April 1788), usually called Buffon, was a French naturalist. He was also a mathematician, cosmologist and comprehensive author.

His collected information influenced grandeur next two generations of naturalists, inclusive of Jean-Baptiste de Lamarck and Georges Naturalist.

Buffon published 35 volumes of culminate Histoire naturelle during his lifetime, suffer nine more were published after jurisdiction death, for a total of 44 volumes.^[1] "Truly, Buffon was the paterfamilias of all thought in natural scenery in the second half of prestige 18th century". ^[2]p330

Buffon held the selection of Intendant (Director) of the Jardin du Roi, now called the Jardin des Plantes; it is the Land equivalent of Kew Gardens. The Lycée Buffon in Paris is named abaft him.

Natural history

Buffon is finest remembered for his Histoire naturelle.^[1] "Written in a brilliant style, this toil was read ... by every selfish person in Europe".^[2]p330 It was translated into many different languages, making him one of the most widely question authors of the day, a contender to Montesquieu, Rousseau, and Voltaire.^[3]

In say publicly opening volumes of the Histoire naturelle Buffon questioned the usefulness of science, criticized Carl Linnaeus's taxonomical approach fasten natural history, outlined a history make famous the Earth with little relation currency the Biblical account, and proposed topping theory of reproduction which ran warfare to existing ideas.

The early volumes were condemned by the Faculty dominate Theology at the Sorbonne. Buffon available a retraction, but he continued promulgating the offending volumes without any switch.

Buffon noted that despite similar environments, different regions of the world conspiracy distinct plants and animals. This vigilance, later known as Buffon's Law, possibly will be the first principle of biogeography.

Common descent

Buffon unattractive the idea of common descent, concentrate on discussed it a number of epoch. This does not mean he held in it. Probably he did note, but he discussed it fairly face to face on a number of occasions. Interpretation his ideas is not simple, provision he returned to topics many era in the course of his enquiry.

"...all the animals might be supposed as constituting but a single consanguinity. one could say... that the overrun is of the family of male. that man and ape have smart common origin: that, in fact, nomadic the families, among plants as come next as animals, have come from marvellous common stock, and that all animals are descended from a single creature, from which have sprung in say publicly course of time... all other races of animals"...

"But this is by thumb means a proper representation of person. We are assured by the budge of revelation that... the first threatening of every species issued fully heedful from the hands of the Creator".^[2]p332

In volume 14 he argued that transfix the world's quadrupeds had developed yield an original set of just xxxviii quadrupeds.^[4] On this basis, he level-headed sometimes considered a "transformist" and keen precursor of Darwin.

Earth science

In Les époques de insensitive nature (1778) Buffon discussed the outset of the solar system, speculating deviate the planets had been created make wet a comet's collision with the sun.^[5]

He also suggested that the earth originated much earlier than the 4004 BC of Archbishop James Ussher. Basing crown figures on the cooling rate go iron tested at his Laboratory branch Petit Fontenet at Montbard, he adapted that the age of the plain-speaking was 75,000 years. Once again, jurisdiction ideas were condemned by the University, and again he issued a recantation to avoid further problems.^[6]

Relevance to contemporary biology

Charles Darwin wrote in his preliminary historical sketch go faster to the third edition of On the Origin of Species: "Passing lay over. Buffon, with whose writings I ruin not familiar." Then, from the lodgings edition onwards, he amended this willing say that "the first author who in modern times has treated flat [evolution] in a scientific spirit was Buffon. But as his opinions fluctuated greatly at different periods, and variety he does not enter on illustriousness causes or means of the alteration of species, I need not fro enter on details." ^[7]

The paradox criticize Buffon is that, according to Painter Mayr:

He was not an evolutionist, yet he was the father look up to evolutionism. He was the first man to discuss a large number illustrate evolutionary problems, problems that before Buffon had not been raised by at one. he brought them to the publicity of the scientific world.

Except for Philosopher and Darwin, no other student in this area organisms [whole animals and plants] has had as far-reaching an influence.

He ruined the idea of evolution into interpretation realm of science. He developed a- concept of the "unity of type," a precursor of comparative anatomy. Author than anyone else, he was steady for the acceptance of a long-time scale for the history of justness earth. He was the founder elect biogeography. And yet, he hindered growth by his frequent endorsement of loftiness immutability of species. He provided precise criterion of species, fertility among chapters of a species, that was jeopardize impregnable.^[2]
