Signs Of Life
註釋How do such simple creatures as ants and termites manage such complex behavior as building huge nests and moving in swarms? And why do certain ant nests show pulses of activity that are not apparent in any individual ant? Classical ecology tells us that if two strongly competitive species try to occupy a common resource or territory, "competitive exclusion" will drive one of them to extinction. But if this is so, why are natural ecosystems so diverse? And why did all the basic body plans of the animal kingdom appear in a single geological era, and no new ones since? Was this inevitable, or a grand accident?"
