Such as when you're swimming, and even when you havent drank anything, you still gotta go. Does our skin take in water when we swim?

Evolution is impossible. People act like religious people are less credible because they accept creationism based on blind faith. Yet, most people believe evolution just because they read it in a sciaence textbook. Isn't that blind faith as well? There is not enough evidence to convince me that evolution happened. If life was sponatneously created, that would mean that a DNA strand would have had to be formed randomly. Just one DNA molecule is miles long, and much of it is the same in all species. Even the first DNA strand must have been at least 50% identical to ours. SO how could this have happened all by itself? Plus the development os sex organs and organs of convenience oculdn't have happened. Two organisms must have mutated opposite sex organs or organelles simultaneously in the same area for sex organs to develop. Natural selection indicates that if we were not exactly the way we are, we would have die. Why are there no species similar to human beings?Icouldsaymorebutimoutofrm

If from experiences that life doesn't come from dead meat, or out of broth, then how do the first organisms get here? Is it possible for the proccess to happen again? I know that biologist think that electricity helped. But, why didn't lab experiments make new life? How did the Acids come together?

Why? And why can a human die anytime in his/her life. How can a human die. How can a human live his/her life knowing that he/she going to die. How do a human live everyday.

I know it would be almost infinitely unlikely, but wouldn't it be technically possible to have twins that are both identical and fraternal? I.e., they come from different eggs but coincidentally have the same DNA?

My friend's 12 year old sister has a friend who has blond hair and blue eyes. Her mother is Korean. I didn't think that this is possible, because blond hair, blue eyes is recessive, and I'm pretty sure that these genes aren't found in the Korean population. Now the mother could be half Korean (my friend wasn't sure), which would make the blond haired, blue eyed child possible. But for the sake of this question, I'm assuming the mother is full Korean, and the kid wasn't adopted.

So far, no opposable thumbs, fire or (to my knowledge) vocal chords to allow communication. No tool-making abilities either, and few social rituals. But if http://uk.answers.yahoo.com/question/index;_ylt=Ag3mflkzaExNaLIWnidRKUcgBgx.?qid=20060617151152AA5IK9H comes to pass, it strikes me that being aquatic might give you a bit more stability to survive the apocalypse that wipes out the humans.
