Karl Friedrich von Gaertner (or Carl Friedrich von Gärtner) (May 1, 1772 – September 1, 1850) was a well-known German botanist, and the son of Joseph Gaertner. He was a pioneer in the study of hybrids, and he is considered an important influence for Gregor Mendel. Gärtner, who was a protestant,〔Ute Deichmann, Anthony S. Travis (2010), "Darwinism, Philosophy, and Experimental Biology", p. 51〕 challenged the doctrine of Carl Linnaeus of the "new special creation" which stated that new species of vegetation could arise through hybridization. He defended the stability of species, and argued that although the transmutation of species was evidently possible, the new species would not last because of a ''law of reversion'' which prevented them from spreading freely.〔http://www.macroevolution.net/support-files/forms_of_life.pdf〕 As was reported in the words of Mendel: Gärtner is mentioned 17 times in Gregor Mendel's short famous paper ''Experiments on Plant Hybridization'' and 32 times in the first edition of Charles Darwin's "''The Origin of Species''". == References ==
