E. O. Wilson
Edward Osborne Wilson (born June 10, 1929) is an American biologist, researcher (sociobiology, biodiversity, island biogeography), theorist (consilience, biophilia), naturalist (conservationist) and author. His biological specialty is myrmecology, the study of ants, on which he is considered to be the world's leading expert.Wilson is known for his scientific career, his role as ""the father of sociobiology"" and ""the father of biodiversity"", his environmental advocacy, and his secular-humanist and deist ideas pertaining to religious and ethical matters. Among his greatest contributions to ecological theory is the theory of island biogeography, which he developed in collaboration with the mathematical ecologist Robert MacArthur, and which is seen as the foundation of the development of conservation area design, as well as the unified neutral theory of biodiversity of Stephen Hubbell.Wilson is (2014) the Pellegrino University Research Professor, Emeritus in Entomology for the Department of Organismic and Evolutionary Biology at Harvard University, a lecturer at Duke University, and a Fellow of the Committee for Skeptical Inquiry. He is a Humanist Laureate of the International Academy of Humanism. He is a two-time winner of the Pulitzer Prize for General Non-Fiction and a New York Times bestseller for The Social Conquest of Earth, Letters to a Young Scientist, and The Meaning of Human Existence.
