I knew that some whacked out liberal vegan would come up with something to prove eating red meat did us great harm. Just as they found a “gene” for being a queer now we have a molecule that gives us aids because we eat red meat. It’s seems strange to me that mostly gays and drug users get aids, does that meant the rest of us don’t eat meat?

I think you may have misread, or failed to understand, the article.

It seems there was a price to pay for some of the beneficial mutations that led to genus Homo some three million years ago.

Actually there are no such thing as beneficial mutations. Plus the first sentance said that eating red meat by homo sapiens produced a molecule that led to us having aids. I strongly disagree with that and I misread nothing. This guy is blaming red meat for something that is caused by certain life styles, and is covertly saying red meat bad, veggies good.

There is almost always a “price to pay”. The concept is called antagonistic pleiotropy, also known as “no such thing as a free lunch”.

No wonder the Communists hated Biology, all that competition, unequal outcomes and trade offs. ;)
