Why do you all say nothing about evolution was an accident or just "created"?
I'm not going to go on a little rant about how the Bible is real and whatnot, I personally believe in evolution, and I do believe in other things as well, even if it isn't necessarily any type of divine thing like God; so please just listen.
Not all evolution happens from environmental stresses, so yes, evolution can happen randomly and on accident.
This is quite rare, but there are times when mutations happen in genes. When these mutations are beneficial, they can often cause evolution. These mutations are in fact random. So please, know your stuff before you say something, if you don't it's only going to bring criticism and won't help you to prove your point at all.
@whoever answered first: Actually they do. It's called allopatric speciation. If a one population of a species gets separated from another in a different environment, that environment puts stresses on the ``trapped`species, and only the individuals well suited to the stresses will survive, which leads to Natural Selection. Eventually a new species will be formed, or evolved, and they won`t be able to reproduce with the old species.
edit again: this part wasn't about mutations, most evolution is just from desirable traits that come from sexual reproduction (according to my textbook anyway). The environment is what causes the evolution, because if it weren`t for changes in the environment, leading to stresses, then the species wouldn`t have to evolve.

You are 100% correct. Evolution, as we now understand it, is the result of a combination of natural selection and random mutations. If the mutations help the organism adapt to changing conditions, then that mutation will survive. Now let me throw an idea at you. Could you conceive of the possibility that an outside agent could engineer mutations in Earthly organisms so as to create a new species? Who's to say that didn't happen? Intelligent design on a limited basis, combined with natural evolution? How about that?

No form of evolution is caused by "environmental stresses". Mutations happen by accident and those mutations prove to be beneficial to the particular environment in which an animal lives.
That animal then has a better chance of passing on it's genes until the mutation becomes a part of the animals make up.
EDIT: Yes, but the new environment doesn't CAUSE the mutations and therefore the environment doesn't CAUSE evolution. It happens randomly.

Sounds like a straw man to me. People are aware that the mechanism of evolution mainly involves genetic mutation, genetic drift and natural selection.
