Since 2002 it has channeled the heat produced through insulated pipes toward greenhouses where tomatoes are grown commercially on 42 acres...

It's a controversial claim, one disputed by anthropologist C. Owen Lovejoy of Kent State University. "Brains don't expand because they were permitted to do so," he says. "They expand because they were selected"--because they conferred extra reproductive success on their owners, perhaps by allowing them to hunt more effectively than the competition...
