There has been much controversy in recent years about the teaching of evolution and/or special creation (aka:intelligent design) in schools. -- What is the difference between evolution and natural selection? How could beliefs about special creation/intelligent design be in agreement with the theory of natural selection? How could they be in disagreement?

Bacteria are certainly the most numerous organisms on Earth, they live in nearly all environments, and they are the least suspectible to being eliminated through environmental catastrophe. Are they Earth's most successful organisms? Why do you agree or disagree with this concept?

One of the distinguishing features of animals is that their cells do not have the thick outer lining known as a cell wall. plant cells have a cell wall, as do fungi cells. Why would such a feature be advantageous for plants, but disadvantageous for animals?

What I mean is for instance; some dogs have 2 spots above their eyes that are there to look like they are awake while they are sleeping, to protect them from preditors. That's pretty smart, so what or who do you think put them there. I doubt that dogs would be capable of (over time) subconciously thinking up that kind of thing. So as an ongoing and active presence what do you think it is, if you don't belive in a God? I'm not trying to prove a point or anything, I just want to know what you think.

Or is it only less likely for men?

I'm pondering this because I have a Widow's peak. Yet my brother does not. And I have read that it is the dominant trait. And none of my family has it, which leads me to believe that my father had the gene. ( I have never met him.) So, my question is, does it only commonly appear in women? Is it equal? Or is something strange going on here?
