Answer: Option A.

Alfred Wallace.

Explanation:

Alfred Russell Wallace was an English naturalist born in January 1823. He independently proposed theory of evolution by natural selection. His scientific ideas encouraged Charles Darwin to work together with him and they both published their scientific ideas in 1858.

Wallace thought that an inferior variety can coexist with another superior variety in the environment, until deteriotion forced the inferior variety to be extinct from the environment and this is totally different from Darwin's view which said that individual with heritable trait are better suited in their environment.
