Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist and anthropologist who specialized in comparative anatomy.He has become known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
Thomas Huxley, one of the small group with whom Darwin had shared his theory before publication, emerged as the main public champion of evolution. He wrote a favourable review of " Origin " in The Times in December 1859, [ 13 ] along with several other articles and delivered a lecture at the Royal Institution in February 1860.
In 1804, Dalton explained his atomic theory to his friend and fellow chemist Thomas Thomson, who published an explanation of Dalton's theory in his book A System of Chemistry in 1807. According to Thomson, Dalton's idea first occurred to him when experimenting with "olefiant gas" ( ethylene ) and "carburetted hydrogen gas" ( methane ).
In the early 19th century prior to Darwinism, Jean-Baptiste Lamarck proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory, originally ...
Using his theory, he discovered homologies showing that slightly changed body parts served different functions to meet new conditions, and he found an intermediate stage in the evolution of distinct sexes. [44] [45] Darwin's barnacle studies convinced him that variation arose constantly and not just in response to changed circumstances.
Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species. [ 17 ] [ 18 ] By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact .
