All mutations are completely random. but it is the natural pressures from the environment from which the animal is located that "weed out" the traits not suited for that particular environment.

well, then howcome now whenever a human or animal has an "accidental mutation" it results in brain damage or permanent physical dissability or death?

inferior traits are weeded out through natural selection.
example: malaria in africa was a very large problem. a mutation occurred that's called sickle cell anemia. this trait, or mutation, made the blood cells that malaria attack sickle shaped. malaria enlarges red blood cells until they die, but the sickle shaped blood cells were immune. this allowed the human with the mutation to live longer than others, making the human more able to pass on that superior trait.
thats all evolution is. random mutations being passed on. heck, they mutations dont even have to benefit the animal acording to the definition. but over millions and millions of years those little traits can really build up.

besides all that. i have a REAL problem with evolution being presented as fact. it's NOT, it's a theory. it has NEVER been proven as absolute, unquestionable fact. therefore, it is still a theory, and it needs to be taught and presented as one. and in public schools, if they teach me evolution, they damn well better treat it as a theory AND they better teach Creationism along with it.

a theory isnt just an educated guess. theres a lot more that goes into a theory, like evidence. creationism lacks any real scientific evidence.
theres lots and lots of proof. but science is rarely fact. newtons LAWS of motion, are technically just theories too. some proof is similarities in early development, homologous body structures, geographic distribution, and vestigial organs. until there is enough proof against evolution, then it should be the main theory, and taught in schools.
