Some men reach for the stars, while others stare at the ants on the ground. That observation helped turn E.O. Wilson into one of the most esteemed writers, scientists and naturalists of this or any era. The "Nova" (7 p.m., PBS, check local listings) profile "The Ant Man" is narrated by Harrison Ford.
Now 78, Wilson claims he's still the same "boy" who spent his "savage years" deep in the Alabama woods studying nature. A boyhood fishing accident cost him his sight in one eye, and helped propel him toward the study of tiny creatures he could examine with a microscope through his one remaining eye.
Wilson's fascination with bugs led him to study possible genetic reasons behind their behavior and highly structured societies. His 1975 work "Sociobiology," which argued that evolution could explain social behavior in insects, and possibly even in humans, sparked wide controversy.
In more recent decades, Wilson has been widely praised for his public crusade to raise awareness of the threats to the diversity of life on Earth. Naturalist and filmmaker David Attenborough says Wilson will "go down in history for opening the world's eyes to biodiversity." Not bad for an Alabama boy obsessed with bugs.
