ok, of the four, three would probably be in early man's diet.
The human body can convert K1 (Spinach, Kale etc) to K2, but not very efficiently.
so, early man, who had stronger, more enameled teeth, might be more likely to have been a milenia-generational brain, egg and bone-cracking marrow eater, consuming a lot of K2 sources, before become more of a veggie/nut eater? Is that possible?
That's the theory. What makes you think that early man was a big veggie/nut eater ? Humans have been omnivores for a long time.
