I've been thinking a lot about evolution lately. I wonder, for example, whether the use and abuse of drugs might be considered a form of evolutionary test, a way to make up, however imperfectly, for the absence of immediate threats to survival among the privileged people of the developed world. I doubt whether there's a scientific basis for this hypothesis. But I am nonetheless taken with with idea that something deep within us cries out for near-death experiences. Perhaps the fondness for fast food could be explained with the same logic.
Anyway, all that contemplation of the human brain frying over easy in a vintage Lodge skillet came to mind when I read this story about a monkey that has, at least temporarily, "evolved" into bipedality:
Could brain damage unlock the doors to a brave new world?
