Carl Christoph Vogt (5 July 1817 in Gießen, Grand Duchy of Hesse – 5 May 1895 in Geneva, Switzerland) was a German scientist who emigrated to Switzerland. Vogt published a number of notable works on zoology, geology and physiology. All his life he was engaged in politics, in the German Frankfurt Parliament of 1848-9 and later in Switzerland.
In 1847 he became professor of zoology at the University of Giessen, and in 1852 professor of geology and afterwards also of zoology at the University of Geneva. His earlier publications were on zoology. He dealt with the Amphibia (1839), Reptiles (1840), with Mollusca and Crustacea (1845) and more generally with the invertebrate fauna of the Mediterranean (1854). In 1842, during his time with Louis Agassiz in Neuchâtel, he discovered the mechanism of apoptosis, the programmed cell death, while studying the development of the tadpole of the midwife toad (Alytes obstetricians). Charles Darwin mentions Vogt's support for the theory of evolution in the introduction to his The Descent of Man, and Selection in Relation to Sex (1871).
Vogt was active in German politics and was a left-wing representative in the Frankfurt Parliament. Karl Marx scathingly replied to attacks by Karl Vogt in his book Herr Vogt (1860). Marx's defenders pointed to the fact that, years later (1871), records published after the fall of the Second Empire of Napoleon Bonaparte III indicated that Vogt had been secretly in the pay of the French Emperor.
Karl Vogt was a proponent of polygenist evolution; he rejected the monogenist beliefs of most Darwinists and instead believed that each race had evolved from a different type of ape. Vogt believed that the Negro was related to the ape. He wrote the White race was a separate species from Negroes. In Chapter VII of his Lectures on Man (1864) he compared the Negro to the White race and described them as “two extreme human types”. The differences between them, he claimed, are greater than those between two species of ape; and this proved that Negroes are a separate species from Whites.
