““{ On to contributions to evolutionary biology of 18th century French scientist, Georges-Louis Leclerc, Comte de Buffon } He was not an evolutionary biologist, yet he was the father of evolutionism. He was the first person to discuss a large number of evolutionary problems, problems that before Buffon had not been raised by anybody… he brought them to the attention of the scientific world. Except for Aristotle and Darwin , no other student of organisms [whole animals and plants] has had as far-reaching an influence. He brought the idea of evolution into the realm of science. He developed a concept of the "unity of type", a precursor of comparative anatomy. More than anyone else, he was responsible for the acceptance of a long-time scale for the history of the earth. He was one of the first to imply that you get inheritance from your parents, in a description based on similarities between elephants and mammoths. And yet, he hindered evolution by his frequent endorsement of the immutability of species. He provided a criterion of species, fertility among members of a species, that was thought impregnable.””
