Thomas Henry Huxley was an
English biologist who was termed "Darwin's Bulldog" for his defense of
Charles Darwin's theory of
evolution. His scientific debates against [Richard Owen]
? demonstrated that there were close similarities between the cerebral anatomy of
humans and
gorillas. Interestingly, Huxley did not accept many of Darwin's ideas (e.g. gradualism), and was more interested in advocating a
materialist professional science than in defending
natural selection.
A talented popularizer of science, he coined the term Agnosticism. Huxley was also the grandfather of Aldous Huxley.
