Vestiges of the Natural History of Creation in the context of "Transmutation of species"

Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist and anthropologist who specialised in comparative anatomy. He has become known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution.

The stories regarding Huxley's famous 1860 Oxford evolution debate with Samuel Wilberforce were a key moment in the wider acceptance of evolution and in his own career, although some historians think that aspects of the surviving story of the debate are a later fabrication. Huxley had been planning to leave Oxford on the previous day, but, after an encounter with Robert Chambers, the author of Vestiges, he changed his mind and decided to join the debate. Wilberforce was coached by Richard Owen, against whom Huxley also debated about whether humans were closely related to apes.

Robert Chambers FRSE FGS (/ˈtʃeɪmbərz/; 10 July 1802 – 17 March 1871) was a Scottish publisher, geologist, evolutionary thinker, author and journal editor who, like his elder brother and business partner William Chambers, was highly influential in mid-19th-century scientific and political circles.

Chambers was an early phrenologist in the Edinburgh Phrenological Society. He was also the anonymous author of Vestiges of the Natural History of Creation, which was so controversial that his authorship was not acknowledged until after his death.
