Darwin's contribution was the theory of natural selection that explained the mechanism behind evolution.
Wallace's contribution was almost similar to what Charles Darwin's theory of evolution is. Is that helpful?
his development in science is that he created the natural selection
No, natural selection is believed to result in evolution.
Natural selection means survival (and breeding) of the fittest, it is key to the evolutionary process.
Perhaps not, but evolution can exist without natural selection.
Natural selection is one of the 'guiding' principles of evolution.
he discovered natural selection and the theory of evolution
Evolution by natural selection.
It didn't, actually. While natural selection isn't the complete story of evolution, it is the single most important part of it, and all discussions of evolution must inevitably involve natural selection in some form.
