Who was known as "Darwin's bulldog" for defending his theories?

Thomas Henry Huxley earned the nickname "Darwin's bulldog" due to his vigorous defense of Charles Darwin's theory of evolution through natural selection. Huxley's support was crucial during a time when Darwin's ideas faced significant skepticism and opposition from both the scientific community and the general public. Huxley was known for his eloquent and passionate debates on evolutionary theory, particularly during discussions at scientific societies and public lectures. His arguments helped to clarify and validate Darwin's ideas, making them more acceptable to a wider audience. Huxley's work in comparative anatomy and his commitment to empirical evidence greatly contributed to the establishment of evolutionary biology as a scientific discipline.
