As Freeman Dyson tells it, "If we are wise, science gives us opportunities to leave things better than the way we left it." To a packed ballroom of more than 500 faculty, staff, students and alumni, Dyson expanded on how the the proliferation of genetic engineering and biotechnology soon will circumvent the Darwinian principles that have governed evolution for three billion years. His lecture, "Life After Darwin: The Open Software of Gene Transfer," spoke to the social and economic consequences of this biotechnological upheaval and the resulting explosion of biodiversity. "Biotechnology will become domesticated--no longer seen as weird and alienated," he predicts. "With new tools come new questions and new responsibilities."
