> Mankind evolved to eat red meat. We developed fire for it.
I read somewhere that in some sense minkind devolved to eat red meat. Some gene was damaged, which helped humans to do a marathon activity to track red meat running away (IIRC something to do with an ability of blood to carry oxygen), but humans lost a key enzyme to process fatty acids from red meat. So mankind got more proteins but started to die from heart desease. Probably it was no so bad then because an average lifespan was too short to develop severe symptoms.
