That chart ignores that humans have been using tools & fire to process our food before we even became homo sapiens. You don't need to evolve better meat eating teeth if you instead evolved more dexterous that can create tools to cut up the meat; you don't need strong stomach acid to kill harmful bacteria if you evolved a brain smart enough to use fire to kill the bacteria, and so on.

Plus every single stone age tribe we have observed, from the Inuit of northern North American to the aboriginals of Tasmania, from the remote Amazon tribes to the Khoisan of southern Africa, were all regularly eating meat when the first people who knew how to write things down encountered them. If humans are 'supposed to be' frugivores, how come no group of humans (outside of a fringe movement in countries that have by historical standards huge amounts & varieties of food available) have decided to eat that way? Its not like the Sentinelese are being peer pressured by other groups to eat meat.
