Venom Evolution 4of5

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?

Rattlesnakes would not need to evolve stronger venom to beat the squirrels as long as the snakes are able to find enough baby squirrels (or other animals) to survive and reproduce.

Squirrels are also communal animals, so a "slightly more effective" bite might not even be enough when its friends are around to scare-off or kill the snake. It really depends which animals evolves the best trait first.

Everything about American culture is based on excess, from the food portions to the gushing emotion of their television.

It is a product of their short history combined with the countries excessive wealth. That combination inevitably leads to gluttony of every kind.

the tails from the squirrels are deadlyer then the snakes

Why does american speakers always have to make it sound like an action movie? It's such a strange habit of the american culture, and it distracts so much from the message.

Imagine how much extra info he could present in the time he uses at refrasing the same basic information in various dramatic sentence structures. Annoying as hell!

But also a little funny, and sometimes it even add some good to the oveall presentation. But shot up, and give me some raw info instead trailerfying the subject.
