Fundamental Religion Promotes Evolution

I thought you could appreciate the humor (from Ars Technica).

Evolution driven by religion, at least in fish: The religion in this case is a pre-Columbian ritual that takes place annually in Mexico, where participants go to a cave and place a toxin in the water to harvest some of the fish that live there. The ceremony has now been going on for long enough that the fish at the site of the ritual have evolved increased resistance to the toxin compared to those living elsewhere in the same cave. Presumably, if this continues long enough, the ritual may come to an end simply because the fish no longer feel any effects of the toxin.
