We now have "reverse evolution".

Throughout mankind's anthropological history the more intelligent apes have always been the ones to survive while the lesser intelligent apes perished. However, now that we have evolved into 21st Century Humans, our course of evolution is starting to turn back. Less-intelligent people are mating with equally inferior intellects thus producing many children of even lesser intellect than their parents. Meanwhile, the smarter beings are using birth control as they are aware that the population of the Earth is nearing its maximum and the smarter people are also aware of how difficult it is to feed more than 2 children. As more and more lesser-intellects are entering the work force we begin to see tell-tale signs of "devolution" such as increased crime, more war, more poverty and electing George W. Bush as President.
