Religious Ceremony Leads To Evolution of Cave Fish

An anonymous reader writes "A centuries-old religious ceremony of an indigenous people in southern Mexico has led to evolutionary changes in a local species of fish, say researchers at Texas A&M University. Apparently since before Columbus arrived, the Zoque people would venture each spring into the sulfuric cave Cueva del Azufre to beg the gods for bountiful rain. As part of the ritual, they released into the cave's waters a leaf-bound paste made of lime and the ground-up root of the barbasco plant, a natural fish toxin. The rest is worth reading, but the upshot is that the fish living in the cave waters eventually got wise, genetically speaking."

    Looking at http://twitter.com/sarahpalinusa, the grammar is better than that, but I can actually feel some of the crazy.
    Admittedly, at 137 characters, that's mainly creative get-under-limit work, but I probably would have rewritten the message by the time i started doing that much character-cutting (though that's just me)

    I hate to refudiate you, but I just looked at a bunch of them and kinda disagree.

    Similar behavior by the native peoples drove half the large species in North and South America to extinction. Sort of hard to see how this could be labeled evolution.

    Er -- do you assume that fundamentalist Christianity is the only religion there is?
