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

Once again, natural selection vs. DNA adaptation/mutation. Two different things.
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.
Not entirely true. There are other causes of mutation other than radiation.
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? |
First of all no - we aren't arguing different things. You're spouting stuff that's wrong, and I'm setting you straight as to why what you're saying is wrong and telling you what is right. Make no mistake of that.
You say that mutations occur and it becomes part of your DNA and then you give me a link to prove your point. Except the link says:

Barbara Biesecker, M.S.: Overall, no. But in each cell there are spontaneous mutations (changes) and activation of genes. So DNA is dynamic even though you are born with all the DNA you will have in your body cells throughout your lifetime.

Proving my point exactly. Changes in DNA occur at the cellular level due to radiation and things like that but there are no overall changes in DNA.
Someone inherits a trait by that trait being passed onto them from their parents. Over time, people with certain traits are more likely to survive and have children and that's how traits develop.
The son of an alcoholic only gets that trait passed onto him because his father ALSO had that trait passed onto him by one of his parents, and if you follow the chain down far enough that same trait was introduced by natural selection for some reason or another.
Just because you spent your life becoming a body builder it doesn't make your kid any better at becoming a body builder. The kid may get that gene that gives them the ability to become one and the ability to build muscle but it is the same gene that you had that let you do the same thing and it was passed onto you from your parents.
When a DNA mutation happens it happens in a single cell, not all across the board on your body. Overall the DNA you are born with is the DNA that contains the code to everything in your life from birth - to death. Outside influences can affect that but they do not alter that code that was there when you were born.

makes sense, please continue
50 'gene 50' mutates

Neither an unborn baby or a pregnant woman has DNA that is mutating. When the egg is fertilized by sperm and that initial cell is formed it contains the DNA that will tell your cells how to build a human. That same DNA is reproduced and can be found in every single cell in your body.
