New research released Thursday by Stanford University biologists indicates that in a single generation, human beings have evolved to the point where they can no longer hear anything college basketball commentator Dick Vitale says. 'It's amazing the ways our genome will adapt to help us survive,' said lead researcher Dr. Ramona Collier, who designed a study subjecting 540 undergraduate students to recordings of Vitale's commentary and frozen-pizza commercials. 'Humans whose auditory systems can't process Vitales voice arent distracted by his overzealous yelling, repetitive catchphrase usage, or weak, unfocused analysis. Consequently, they are more alert to potential threats, opportunities to reproduce, and other information vital to their lives.' Collier suggested it is surprising Vitale himself has not yet been thinned from the herd, as he makes an easy target for predators who can hear his shrieks, spot his flailing arms, and smell his unabashed bias toward Duke.
