Nature abounds with examples of mutualistic relationships. Think of bees pollinating flowers whose nectar nourishes the bees. Each species benefits the other, and together their chances of survival are better than if they lived apart. Now scientists have found that such mutualistic relationships aren't always set in stone. Depending on environmental conditions, once-simpatico species can become competitors, and in extreme cases, one species can even drive the other to complete extinction.
