Argument #1: Transitional Fossils

[Coffee Jesus]

I hope some day you can evolve beyond insults, obscenities, and vulgarity.

It's not that we dislike you. We just want you to argue better (and use better grammar).

When evolution occurs, the rate at which a form changes is not constant. Sometimes changes in the form occur very rapidly and sometimes they occur very slowly. Trilobites appeared when evolution "settled" on a particular form.

Who or what decides this? Is evolution some sort of supreme being that says - ok, you turn into this then stop and you are gonna be this?

The ecosystem. A species adapts to its environment. If the environment changes, the species either changes with it or dies off.
As humans, we are perhaps the only species that can flourish in a wide array of enviornments.
