Thomas Henry Huxley was a prominent English biologist and anthropologist.

He specialized in comparative anatomy, which is the study of the similarities and differences in the structures of different species. Huxley is famously nicknamed "Darwin's Bulldog." This title reflects his energetic and controversial advocacy for Charles Darwin's theory of evolution.

One of his most significant moments was the 1860 Oxford evolution debate. In this event, he debated Samuel Wilberforce regarding the acceptance of evolutionary theory. While some historians believe parts of the debate's story are later fabrications, the event remains a key moment in the history of science.

Huxley's path to scientific greatness was unusual because he had very little formal schooling. He left school at age ten due to his family's financial difficulties. Consequently, he became a major autodidact, meaning he taught himself most of his advanced knowledge. He mastered German, which allowed him to act as a translator for Charles Darwin. He also learned Latin and enough Greek to read the works of Aristotle in their original language.

Through intense self-study, he became one of the finest comparative anatomists of the late 19th century.

His early professional training involved several medical apprenticeships. At age thirteen, he worked with John Cooke and later Thomas Chandler in London. At sixteen, he attended Sydenham College, a low-cost anatomy school. He later studied at Charing Cross Hospital under Thomas Wharton Jones. Although Huxley won a gold medal for anatomy and physiology at age twenty, he never completed his final exams. This meant he did not obtain a formal university degree.

However, his deep knowledge and exam successes allowed him to join the Royal Navy.

At age twenty, Huxley served as an assistant surgeon and marine naturalist aboard the HMS Rattlesnake.

The ship embarked on a voyage of discovery to New Guinea and Australia in 1846. During this time, Huxley focused his research on marine invertebrates. He made significant discoveries regarding the classification of these organisms. For example, he united the Hydroid and Sertularian polyps with the Medusae. He named this new class Hydrozoa.

He observed that these creatures shared a specific structure consisting of two cell layers enclosing a central cavity. This work helped clarify the relationships between many groups of animals.

Huxley's anatomical expertise extended to vertebrates and paleontology. He studied the relationship between apes and humans, a topic that was highly controversial at the time. By comparing the fossils of Archaeopteryx and Compsognathus, he correctly concluded that birds evolved from small, carnivorous dinosaurs. He also solved complex biological puzzles, such as identifying Appendicularia and Ascidians as tunicates. These organisms are now recognized as a sister group to vertebrates within the phylum Chordata. His ability to link different species through physical structure revolutionized biological understanding.

Throughout his career, Huxley held numerous prestigious positions in the scientific community.

He served as a professor of natural history at the Royal School of Mines for thirty-one years. He also held roles as the president of the Royal Society and the British Association for the Advancement of Science. In 1869, he coined the term "agnosticism." He used this term to describe a way of framing claims based on what is actually knowable versus what is not. He was a tireless advocate for scientific education in Britain and fought against extreme religious traditions.
