Re: Perhaps a dumb question
Considering that everything living today is the result of every generation prior lived long enough to reproduce the next that goes back to the Cambrian era, wouldn't the entire DNA sequence be nothing but mutations?
To go from a small multi-cellular organism with parts and the continuous alteration that has occurred since it all began I would think that everything in our DNA is a mutation.

Re: Perhaps a dumb question
Maybe if they look at the genes that start with only one gene for example: olfactory. In chimps they have one gene while we have 8 or 9 genes. Clearly our olfactory abilities are reduced in humans while chimps olfactory abilities are excellent.
Just a thought.

Fears
I have to agree that it must be genetics because I should fear bees. When I was a kid I sat in a hive of yellow jackets and those bees followed me to my house 2 blocks away. I was stung luckily only 6 six times but the next day a bee was still in my house because I was stung again.
This happened back east and now I live in Arizona and I was stung again a couple of years ago. One thing I did notice is their venom is much stronger than the bees back east. I became ill from that sting.
