Thomas Henry Huxley (1825-1895)

In nineteenth century Great Britain, Thomas Henry Huxley [3] proposed connections between the development of organisms and their evolutionary histories, critiqued previously held concepts of homology, and promoted Charles Darwin?s theory of evolution [4]. Many called him Darwin?s Bulldog. Huxley helped professionalize and redefine British science. He wrote about philosophy, religion, and social issues, and researched and theorized in many biological fields. Huxley made several methodological contributions to both invertebrate and vertebrate embryology [5] and development, and he helped shape the extra-scientific discourse for these fields.
