Your DNA doesn't mutate after you're born, your DNA is the same when you're born and when you die.

Yes it does. Once again, mutations occur and those become a part of your DNA.

Adaptation isn't passed on to your kids. The way it works is if there are 100 men and 50 of them aren't hairy enough and don't have fast enough metabolisms then those 50 die and don't have children. The result is children that are hairy not because their parents adapted and passed that on to them but because of natural selection only the ones who could handle their environment survived.

Once again, natural selection vs. DNA adaptation/mutation. Two different things.

Over thousands and hundreds of thousands of years, different traits are selected for and passed onto future generations. The ones that don't possess those traits tend to die and the ones that do tend to live.
|
How does one "inherit" a trait? How about the susceptibility of getting a disease more than someone else because it's in your genetic makeup? The son of an alcoholic has more of a chance of becoming an alcoholic because of gene mutations that are passed down in the form of DNA.

When DNA mutates it's because of something like radiation. Every time your cells multiply they make a copy of the DNA and sometimes radiation and things like bad copies happen where one or two things is out of place. Sometimes that leads to things like cancer.

Not entirely true. There are other causes of mutation other than radiation.

Everyone in the world doesn't look the same because people are a product of two other people.

I'm not talking about general looks. I'm talking about overall features and coloring.
You have your points and I agree with some, but I feel like we're debating two different things so there really is no winner. We're in the same area, just not playing the same game. I'm not going to debate natural selection because I wholeheartedly believe it to be scientific fact. But we're talking about different things, would you respectfully agree?
