Step 1 : Introduction to the question "Who is considered the founder of the theory of evolution?"
...Darwinism is a theory of biological evolutiondeveloped by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Step 2 : Answer to the question "Who is considered the founder of the theory of evolution?"
Charles Darwin is best known for his contributions to the science of evolution. Darwin’s theory of evolution declared that species survived through a process called "natural selection," where those that successfully adapted, or evolved, to meet the changing requirements of their natural habitat thrived, while those that failed to evolve and reproduce died off. In 1859, he published a detailed explanation of his theory in his best-known work, On the Origin of Species. Darwin’s theory of evolution and the process of natural selection later became known simply as “Darwinism.”
