Asteroids like this, they think, have occasionally crashed into the earth with catastrophic consequences, and they strive to calculate how frequently these inopportune meetings occur...

But if they occur at all, they could shake the foundations of evolutionary biology and call into question the current concept of natural selection. Should the Alvarez theory be correct, says Harvard Paleontologist Stephen Jay Gould, the importance of competition between species diminishes. If every so often a megablast opens up a broad array of ecological niches, then new creatures can flourish without having to crowd out the old. "If you ask the question, 'Why are we here?' " says Gould, "the answer is, 'Because the dinosaurs disappeared...

Despite these bright prospects, success is not assured and will probably not occur without the active help of those in positions of academic leadership. For all the experiments and publicity, we still have little first-rate software.

Small wonder, since good programs often require more than 200 hours of preparation for a single hour of instruction. To surmount this barrier, university administrators will have to do much more than shower their campuses...
