Introduction Charles Darwin born 12 February, 1809 was an English geologist and naturalist. Alfred Wallace born 8 January 1823 was a British explorer, naturalist, geographer, biologist and anthropologist. Darwin and Wallace are highly regarded for their significant contributions to the theories of evolution. It is very important to compare the individual lifestyles, contributions, and beliefs of Darwin and Wallace in order to develop a clear and comprehensive understanding of their concepts of natural selection in evolution. According to Janet Browne (2010) in her biography of Darwin, she describes the similarities in the life experiences of Darwin and Wallace that led them to independently arrive at the theory of natural selection. Both Wallace and Darwin were inspired by the readings such as Charles Lyell and Thomas Malthus. Browne notes that, “Even so, the parallels between Darwin’s and Wallace’s ideas are no less remarkable for their cultural symmetry. Their similarities are further demonstrated by them sharing similar geographical exploration and travel experiences and their mutual appreciations of their marvels of nature and overwhelming desire to comprehend them…” (Browne 2010: 357). The two theorists examined the concepts of natural selection independently until its publication. By the 1958, Darwin had already developed his idea on natural selection but had not published it as he was still collecting more evidence. After his previous research had been destroyed in his journey back to England from Brazilian Amazon, Wallace resumed his research on natural selection while at Archipelago which was marked by his famous “letter to Darwin” that contained an essay discussing a theory very similar to Darwin’s. The situation was very challenging as these two theorists had been independently studying the same topic with almost similar outcomes. These events led to
