Venom Evolution 5of5

Venom confers an amazing advantage as a predator to any organism who has it. It often means that the bearer does not have to be as big or fast in the battle of survival. It also has the advantage of providing a fantastic defence mechanism against your potential predators. It is in esscence, chemical warfare. Various forms of venom usually contain a vast array of different toxins which can inflict damage in many different way. How did venom evolve? In response, how have predators and prey alike, evolved their own response to dealing with venom?

Great series, thanks for posting it! (Though I was hoping they'd talk about Frys research of Colubrids...:)

Alas, whenever you discuss snake venom, you invariably spend the time on vipers, elapids and occasionally hydrophiids. Boomslangs are so under rated.

man dont fuck with snails

Then the venomous species says to predators : dont eat me please. And they behave that way too. But they choose to eat others when they are hungry. So it is foul play.

[icemindreallife]

the inverted process of producing toxin and producing the normal constructive food for other animals, is the meaning of survive, food and venom. It is very strategical about venom. The human protein, carbohydrate, and fat is what the body is made from. But if species does not do anything about this, then they will attract other animals to prey on them. eventually they reverse the process of feeding, and produce venom.

[icemindreallife]

If humans are unable to hunt for food, they will evolve glands that produce venom, and they will hunt more easily, that is how vampires extinct, because humans don't accept humans who have fangs and eventually all humans are civilized.
