Things evolve, or so I'm told, when they are faced with a problem that could wipe them out, or at least harm them. Such as trees growing taller, sharks jumping out of the water, and insects that blend into their surroundings. But haven't we, as people, attacked and destroyed about everything that could wipe us out? The way I see it, we no longer need to evolve, because of guns and pesticides, and gentic farming. Has evolution, therefore, stopped within our societies, or are we just stuck in a transitional phase, waiting for aliens or small pox to come and get us?
