crotalusadamanteus said:I think the thing with bees, wasps and ants is that they are "immediate pain causing" venoms, and there for do not need the deadly effectiveness of an advanced "killing" neurotoxin. If the pain can drive the attacker away, thee is no need to kill.
Snake venoms however, you can sumize do not always cause pain. Actually, if i remember right, very few (in US) cause any pain at all till advanced stages of the envenomation. So the snake can still be killed, even eaten by the attacker, even if the attacker is bitten. So there would be a natural need for a faster acting, more toxic venom with snakes.

Perhaps, but we are talking about a Mother Nature who has designed the spines on some lizards to kill a snake that eats one slightly too large when it can't spit it back up because of the orientation of the spines causing it to lodge in the throat. In effect, individuals are designed to die to save the species. If nature "decides" that the most effective way to save a species is by mutating to the point of killing off the main threat (humanity), well things could get interesting.....
Right at this moment, what one influence on this planet is the most threatening to most species existing today?
