Charles Robert Darwin (12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist. He contributed significantly to the science of evolution. Darwin proposed that all species descended from common ancestors over time. This idea is now a foundational concept in science. Working with Alfred Russel Wallace, he introduced the theory of natural selection. This process explains how branching patterns of evolution occur through the struggle for existence.
