Who created the theory of evolution

Darwinism is a theory of biological evolution developed 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.

I'm sure the teacher wants Charles Darwin because he confirmed it - but the theory was actually created by Jean-Baptiste Lamarck but that is very little known
