Snakes use their venom for both offensive and offensive purposes for defense purposes, but new research suggests that this ability originally appeared as a strategy for attacking prey, not for self-defense.

That their venom was created for defense purposes is hardly an idea, given the amount of human suffering that these venomous snakes regularly cause.
Figures from the World Health Organization show that about 2.7 million people are bitten by venomous snakes each year, of which 81,000 to 138,000 will die. Needless to say, snakes don't hunt people, but they will strike when threatened.

We wanted to investigate whether defense is a driver for poison development."
