Step-by-step explanation:
Georges-Louis Leclerc, Comte de Buffon, Jean-Baptiste Lamarck, and Georges Cuvier were three influential transformists in the field of biology during the 18th and 19th centuries.

Buffon proposed that species change over time due to external influences, Lamarck suggested that acquired characteristics could be inherited, and Cuvier developed the theory of catastrophism to explain the existence of extinct species.
