I had a professor that suggested polio could have played a serious role in the development of our species. He showed the partial paralyzingly of chimpanzees forced them to "walk upright". There is also an awesome science fiction book called "Darwin's Radio". Great read. It talks about viruses and phages having a direct link to genetic mutation and symbiotic adaptation.

I trust the intelligent design part was tongue in cheek. I also read about this recently. I think it's fascinating.

I heard something about that in passing. Joe Rogan was actually talking about it on his podcast.

Intelligent design? ABSOLUTELY NOT! Over hundreds of thousands of years that relationship has evolved. It is a matter of sheer coincidental mutual adaptation through natural selection.

An interesting article. Incidentally, I never fart, I ventilate gas and so does everyone else because gas is a by product of the enzymatic process of digestion. Of course, there are those who will claim that they do neither, they must be hermetically sealed.
