Alfred Russel Wallace
The theory of evolution by natural selection.
The men Charles Robert Darwin and Alfred Russel Wallace are the co discoverers of the identified theory of evolution by natural selection.
Charles Darwin
Natural selection is what is most closely associated with Darwin.
The naturalist, Charles Darwin, who wrote On The Origin of the Species by Means of Natural Selection, was four years old in 1813. In a letter, he mentioned that one Dr. Wells presented an "Essay on Dew" (which proposed the principle of natural selection) to the Royal Society in 1813.
That is Darwin's principal of Natural Selection, sometimes called survival of the fittest.
He formulated the principle of natural selection, intersexual selection and intrasexual selection which all contributed to the study of evolution.

That selection was natural.
Alfred Russel Wallace is credited as the co-discoverer of the theory of natural selection alongside Charles Darwin. Wallace independently formulated the theory while working in Southeast Asia, sending his findings to Darwin in 1858, prompting the publication of the joint paper "On the Tendency of Species to Form Varieties" in 1858.
Darwin's principle refers to the concept of natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. This process leads to the gradual evolution of species over time.
