I read an interesting theory once about the emergence of modern man. Based on a number of genetic studies, it appears that humans went through a genetic bottle neck sometime between 100K-50K years ago. At that point there were perhaps less than a thousand humans alive, and no one knows exactly what brought this about. The article I read suggested that our ancestors were preyed upon nearly to extinction by Neanderthals and other hominids. Then, somehow a series of genetic mutations gave us the ability and social skills to organize in larger groups of fifty or more and develop proto-armies larger than the bands of our competitors, while at the same time heightening our aggressive tendencies. This turned the tables on the Neanderthals and we hunted them to extinction..
The Neanderthal EPA put humans on the Endangered Species list. Through centuries of habitat restoration & conservation, captive breeding programs, and managed hunting, we were saved from extinction.
We showed our gratitude by wiping out the Neaderthals, down to the last man, woman and child.
So, does anyone STILL want to save the Snail-Darter?
