E. O. Wilson
Edward Osborne Wilson (June 10, 1929 – December 26, 2021) was an American biologist, myrmecologist, and evolutionary theorist renowned for pioneering sociobiology and advancing empirical understanding of social insects, island biogeography, and biodiversity.[1][2] A longtime Harvard University professor, Wilson co-developed the theory of island biogeography explaining species distribution patterns and authored seminal works like Sociobiology: The New Synthesis (1975), which applied evolutionary principles to animal and human social behaviors, integrating genetics, ecology, and ethology into a unified framework.[3][4] Wilson's monographs On Human Nature (1978) and The Ants (1990, co-authored with Bert Hölldobler) each earned the Pulitzer Prize for General Nonfiction, highlighting his synthesis of natural history observations with theoretical insights into altruism, eusociality, and human instincts.[5][6] His advocacy for conserving half of Earth's land surface to preserve biodiversity underscored causal links between habitat loss and extinction rates, influencing global conservation efforts.[4] Despite empirical foundations in decades of ant fieldwork and comparative studies, Wilson's extension of evolutionary explanations to human sociality ignited controversy, with critics in academia—often aligned with environmentalist or blank-slate paradigms—accusing him of reductionism and ideological overreach, including protests disrupting his lectures; nonetheless, sociobiology's core tenets have gained traction in behavioral ecology and genetics, vindicated by subsequent genomic evidence for heritable behavioral traits.[7][8]
