What [B]makes evolution occur (supposedly)? What is the agent that causes organisms to undergo evolution (supposedly)? [/B]

But what causes (supposedly) the organism to "adapt?" (I want to know the mechanism that causes the change.)
Originally posted by JesusIsAliveThe one individual doesn’t change from one form to another but its offspring will continue the genetic trait that allowed them to survive, hence the long arms.

So are you telling me that a primordial cell evolved over billions of years into a Giraffe without any mechanism causing it? For example, the mechanism that creates horsepower for an automobile is called pistons. The mechanism that turns a tv on or off is called a remote. The mechanism that sends electricity to lamps is activated by a light switch. (Do you see where I am going with this?) The mechanism that makes organisms adapt or evolve into another species (purportedly) is_________________________(fill in the blank).
Originally posted by JesusIsAliveYou are looking for an answer that doesn't exist; there is not a "thing" that causes the adaptation. It is the genetic difference between each individual thing. As in an example between humans of the same species some are stronger, smarter, and faster and so on but we are all of the same species. There is not something that causes it; it is the environment that dictates what that species has to deal with. Your examples have nothing to do with it, and even then your examples are off base. Pistons do not create the "horsepower" and the remote is not what "turns on" the TV, these things are not the main reason but part of it. Pistons without gas and a spark doesn't do squat, you can turn on a TV without a remote and without batteries you remote is useless.

Take a look at bacteria in just one year one species will die off because of antibiotics and the ones that had a stronger resistance to the medicine survived and multiplied and now that antibiotic will no longer work. This is how people start to become immune to antibiotics and the bacteria that were in you just a year ago is completely different.

Pittman, how do you define evolution?

The fundamental premise of evolution stresses the occurrence of modifications in successive generations. Now, what I wanted to know from you is what causes the species to change from, say, a fish to an amphibian, or an ape to a human?
Originally posted by JesusIsAliveThis is where your problem is (well at least with this); it is not a modification of the animal that is evolving as you would think like it grows a limb because it needs to grab a piece of fruit that day. Every animal in the same species is not the same; some are a bit different be it from aggression, intellect or physical makeup. Each will have it own little difference and way it does things.

Looking at Dolphins and Killer Whales, both of these animals have developed a hunting technique to get their pray that stay on the shore line which many times leaves them to be beached and die. With this continued practice the ones that are better suited for this get the fish/seal and live on, the ones that try and are not as good die so that trait is not passed on. Over the thousands of generations if the practice continues and environment plays a huge role in this they can start to develop stronger fins to un-beach themselves or even get farther up the shore.
You are looking for a one word answer or a name of some magical gene that causes fish to walk on land and this is were you are deluded about evolution, it is a process.
