Re: Bump for jjsemsch
Both are "mechanisms" of evolution.

Mutation introduces new genes.
Natural selection changes gene frequency over time.

Re: Bump for jjsemsch
You misunderstand what I mean when I say "new genes"

Yes, one translation of that would be this - "entirely new genes"
However, new variations on existing genes is more representative of what I am talking about.

When Ford introduces a "new car", its a variation on previous cars. I assume you don't show up at the Ford dealer every Presidents' day feeling underwhelmed.
