I noticed everyone LOVES natural selection. I know what it is, and i've read the definition from webster a few times. I wanna know, how can this inatimate object can tell a species, 'your not fitting into your enivronment well, your gone' Or how it tells a species to alter itself to improve the survibility of that species. Natural selection in not a person, place, or thing, its nothing. How can nothing tell something to change or die?

Natural selection means that organisms that DON'T fit in, are less likely to survive then the ones that DO fit in. Why is that concept so difficult to comprehend?
OK, let's put it this way, say I enroll you in a college biology course with a bunch of other people, if you pass the course and move onto the next level course that means you have "survived to reproduce", the IDIOTS like you will be less adapted to passing a biology course and thus will fail the course and not be allowed to go on to the next course, which is analogous to an animal not passing on it's genes to the next generation, whereas the SMART people will pass the course and go onto the next course, which is analogous to an animal surviving to reproduce, as the class of students takes more courses, more of the IDIOTS will be weeded out, and we will be left with smart people who are "well adapted" to a learning environment.
Natural selection and/or the environment "tells" the unfit creature it's not fit by _killing it before it reproduces_, you perfect ass. Too bad, really, that there isn't more of that going around.
It's quite simple really. There are random genetic differences that occur each time a human is produced that are different to its parents. Sometimes, these genetic differences alter the physical structures of an animal.
If the physical structures are beneficial within an environment, for example, they provide better camoflage, then the animal may live longer and be able to produce more offspring, thus sending on its own genes; and propogating the species. In the same way, if the change was not as beneficial, for example, a genetic deficiency then the animal may not be as well adapted to its environment; not live as long perhaps, or not be able to reproduce as well, thus its genes would not spread as far or as quickly and its 'type' would eventually be overrun by the more efficient animal.
THis is what is commonly known as Natural Selection. When it occurs over thousands of millions of years, then the differences can be quite drastic, as I'm sure you can imagine.
For a simple review of natural selection, several tests have been done using fruit flies, also antibiotic resistent bacteria.
Go and learn.
@Hypno Toad,
They've been programmed from childhood to believe that they need permission to live from an invisible master; thus, in their worldview, it is *supposed* to be the universal human condition.
They can't grasp the concept that they are (or once were) perfectly capable of standing on their own two feet; morally, intellectually, and spiritually. They've relinquished their potentials in blind obedience to their strange book and its invisible bogeyman...who has nothing but dreck to offer as far as human conscience is concerned.
Gravity is not a person, place, or thing, its nothing. How can nothing tell something to fall or orbit?
(Mimicking that comma splice hurt me.)
For every random positive micro-step taken, there may well be hundreds of random negative steps. Some die off immediately, some take generations to die, but the ones that just happen to work better, have a better chance of surviving and propagating.
This axiom applies to every level of life form, including ours.
What we are as the modern human race, is the sum of the strongest positive mutations ... keeping in mind that we all have inherited some individual variety of minor negative traits.
"How can nothing tell something to change or die?" I don't know, but if there's no god (as there most likely isn't), wouldn't all of the attributions to "god" in the bible be the equivalent of this as well?
Inanimate object? It's a process which is observable in nature. See the lions take the rhino with the slightly shorter legs at the end of the herd - that's a small part of the natural selection. After it is eaten, it's gone. Easy peasy.
About 99 percent of the species ever present on Earth did not change (enough), and subsequently died.
Oh, by the way; ENGLISH you dolt, learn it. People tend to listen more to you if you can spell and use grammar correctly.
"I wanna know, how can this inatimate object can tell a species, 'your not fitting into your enivronment well, your gone'"
If you think that's a stumper, consider the thermos flask. It keeps hot things hot and cold things cold, right?
How does it know?!
Just as we LOVE photosynthesis.
What inanimate object? Organisms are not inanimate objects.
Either you manage to have offspring or you don't. That's natural selection.
Every single organism has mutations. Some are so bad for the organism that it doesn't make it to birth, some are neutral, and some are beneficial. Some are connected good and bad, like sickle-cell anemia and immunity towards malaria.
Of course natural selection isn't a person or a thing, it's a natural process. How dense are you?
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
