The main point is that humans are evolved to survive - well enough to reproduce and more - on just about anything under the sun, from birdseed to chicken nuggets to seal blubber. That this is true says nothing about the "optimal human diet" ie the diet under which people function best, thus negating the (only) point of the post. I also hate Grok-appeals but there is a pretty major logical fallacy behind that post. It is certainly true that Black Angus steak and broccoli didn't exist in Paleo times, but the flip side is that they are probably, nutritionally, somewhat like what Grok ate. Certainly moreso than a whole grain bagel with fat free cream cheese.
If you are new to the PB - please ignore ALL of this stuff, until you've read the book, or at least http://www.marksdailyapple.com/primal-blueprint-101/ and this (personal fave): http://www.archevore.com/get-started/
Disclaimer: I eat 'meat and vegetables' ala Primal, although I don't agree with the carb curve. I like Perfect Health Diet and WAPF Lactofermentation a lot.
