Whatever deviation has the better chance of survival will have more offspring. It's the beautiful simplicity of evolution.

Natural selection isn't really a force as much as a result. (Please hear me out or else my first sentence makes no sense.) The mutations are random (as you know). However, it's not like 99% of mutations are bad. Some are neutral, some are bad, and some are good. If an organism gets a good trait, it survives longer and has more opportunities to mate. The offspring starts to get a different gene pool, resulting in a seperate organism. (The old type of organism may die out or simply live with fewer members.) Natural selection simply means that organisms that are more fit survive and reproduce.
THIS IS THE MOST IMPORTANT IDEA I HAVE TO OFFER: According to dictionary.com, select has many different meanings, including possessing special or valuable attributes. Natural selection uses selection in that sense of the word. Besides, a rose by any other name would still be controversial.

I am a Christian. Natural selection occurs when one has an advantage over another. An example is a certain species of moth. One was black and one was white. All of the black moths were dark and hard to see by predators, therefore they were not eaten. All of the white moths were much easier to see and were eaten. Therefore, the black moths lived to reproduce many more offspring than the white moths, and the white moths eventually died out, leaving only black moths. This is a real example, although I don't remember the species of moth. If you honestly want to know the answers to your questions, instead of asking us, why don't you take a college course and get educated by experts on this topic? I don't understand why you are asking us. Most of us are probably not experts.
Natural selection IS NOT ACCIDENTAL MUTATION! It is simply the survivial of one species who has an advantage in the environment in which they live. Evolution takes place over millions and millions of years, so each little change adds up to bigger changes over time.
I am a Christian and believe in evolution!!! There is nothing wrong with that. You don't have to believe in evolution, but please become educated on the topic so you don't make Christians look ignorant. How can we ever show the world Christ when we are so close-minded ourselves? Why don't you ask questions like: how can we more effectively help the poor, how can we stop so many teenagers from getting pregnant, etc? These would be questions that would benefit humanity.

"Mother Nature" is a mere personification.! Selection is done by the environment. Those few mutations that make a creature more fit to survive in its environment are passed on to future generations. Those that make it less fit result in the extinction of that line. What's so difficult about that?

I do have self belief in God. yet this somewhat exhibits which you don't comprehend what organic decision is in the 1st place. this occasion might sound stupid even though it exhibits that organic decision acts in extreme college case in point: only the best teenagers come on the right of the class only the main gifted excel in the humanities- organic decision is in basic terms an insignificant term people have coined for the pressures that happen needless to say which settle on who could be the the winner/survivor. Now of direction the call rigidity in college is going to be the instructor,different scholars etc no longer the same pressures that act in the wild >In user-friendly words its in basic terms opposition. only the suitable wins.<

The species itself makes the selection, if it is better adapated for survival in the surroundings it survives and propagates. If it is not it fails and dies off. More species have gone extinct than survived in the history of the planet. Most mutations fail, some survive.

Other animals. The fast deer lives, the slow one gets eaten. The fast mountain lion lives, the slow one starves. The crow that learns to eat berries as well as worms lives when all the worms die, while the crow that eats only worms starves.
It is a balance. Deer and mountain lions make constant small improvements. If they didn't, one or the other would starve. If all deer were capable of 100-mph sprints, none would get eaten by mountain lions and they would eat all the grass in the mountains in a generation or two, then starve to death. If all mountain lions were capable of 100-mph sprints (and were hunting slow deer), none of their cubs would die and they would soon eat all of the deer, then starve.

Individuals make their choices based upon their experience and instincts. We choice who we want to help us procreate, thereby assuring our continuing existence. We shun people with deficiencies (actual or imagined) in favor of those we believe to be worthy (usually those who are like us).

Selection does not imply an intelligence behind the selection.
If you're going to debate scientific reasoning, please take the time to educate yourself rather than simply attempting to poke feeble holes through misguided and misinformed interpretation.

it's not just berth and mutation, its also things like standing on the train track thinking the train will move :)
