I think the changes to our genes can occur from many things including esp. viruses and not just XMRV. I always found it odd that my grandparents were the only people NOT sick during the 1918 Pandemic. They were a nurse and a doctor and took care of others in the hospital and neither grandparent got sick. Then both grandparents and my father worked with TB people closely. I have wondered if THEIR immunity to the 1918 flu and TB might have played into MY CFIDS. Possibly their DNA/RNA was affected (damaged, or whatever) and that got imprinted into MY genes. Who knows. Interesting though.
That really is a WOW statement. Made me think a lot.
Thanks for posting it.
I have always wondered how and why evolution works, as purely random mutations don't seem to be a very good explanation for the speed and accuracy of the way creatures evolve.
