Detailed explanation-1: -Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual.
Detailed explanation-2: -Alfred Russel Wallace (1823-1913) was a man of many talents-an explorer, collector, naturalist, geographer, anthropologist and political commentator. Most famously, he had the revolutionary idea of evolution by natural selection entirely independently of Charles Darwin.
Detailed explanation-3: -Wallace developed some of his most important ideas about natural selection during an eight-year expedition to what was then the Dutch East Indies-modern-day Indonesia-to observe wildlife and collect specimens. Few places on earth can rival this vast archipelago’s tremendous diversity of plant and animal life.
Detailed explanation-4: -Wracked with a fever, he suffered hallucinations, but when the fever broke, the answer came to him-species evolve by adapting to their environment! Wallace knew Darwin was working on similar research. In 1858, he sent Darwin a letter outlining his ideas about evolution.
