I don't know about Wallace, but Darwin spent a lot of his time in the Galapagos Islands where he saw what he thought was natural selection in action without interference from, or as a response to, outside sources like mankind.
Wallace's contribution was almost similar to what Charles Darwin's theory of evolution is. Is that helpful?
Charles Darwin and Alfred Russel Wallace proposed the theory called Natural Selection. This theory explained evolution.
At the Linnaen Society meeting sometime in 1858 Charles Robert Darwin and Alfred Russel Wallace had both their papers presented before the Society on which they proposed the idea of natural selection as a mechanism of evolution.

Wallace.
he was the co-founder of natural selection, along with founder Charles Darwin
Charles Robert Darwin and Alfred Russel Wallace.
The later. Darwin's writings, which are documented, preceded Wallace's evolutionary formulations by some time.
The men Charles Robert Darwin and Alfred Russel Wallace are the co discoverers of the identified theory of evolution by natural selection.
The foreign scientist who influenced Charles Darwin's theory of evolution through natural selection was Alfred Russel Wallace. Wallace independently developed a similar theory to Darwin's, prompting them to present their ideas jointly in 1858. Darwin is credited with the theory of evolution by natural selection, but Wallace also made significant contributions to the field.
The scientist Alfred Russel Wallace actually studied the idea of natural selection before Charles Darwin. Wallace and Darwin later became research colleagues, but Darwin became more well known after publishing "The Origin of Species".

Both Charles Darwin and Alfred Russel Wallace independently discovered natural selection.
