Trying to connect behavior to evolution

I have started a few threads on this in the past that did not go over too well.

Links to prior threads:

Can behavior affect our DNA

I followed a conversation on this yesterday, and it got me to thinking of ways our behavior might be translated in someway to our genetic code we passed on… The only thing I could think of was that chemicals and hormones produced in our brain might react more with certain sperm stimulating them to have a better chance of reaching the egg. I was amazed to discover how close the relationship is between our brain and our semen.

DNA question

What are some of the fantastic possible aspects of DNA that serious scientists suspect. Is there any evidence that the host can alter his own DNA by his behavior.

Question about sperm cells

I know that a sperm is a single cell but how does that cell come into existence, is there a process where another cell changes into a sperm cell? Having just one cell makes it hard to comprehend.
