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.

Well, sure, I agree. But I was questioning why less enamel today and going back to your supposition that less thick tooth enamel might be a multi-generational deficiency of K2,
so, if you can’t get a lot of K2 out of veggie’s, and early man was a leaf-eating omnivore, then why would early man’s tooth enamel be thicker 1.6 million years ago, then today, when man has more access to k2 sources?
the wild guess questions I’m supposing are, is the thicker enamel in early man genetic leftovers from some meat-eating ape ancestor, or Did man gradually lose the ability to manufacture K2? or did the gene for stronger enamel degrade??

...he became nicknamed “nutcracker man”, although Bosei appears to have been a leaf chewer. Leakey thought him to be fruit eating as the teeth are similar to chimpanzees. The omnivour diet would have composed of roots, seeds, eggs, fungi, insects and perhaps reptiles. There is no signs of bone crunching on any teeth.
