This is a good example of how Scientific American has gone from a
once-respected scientific journal to a politically correct one. And
how cognitive dissonance reigns supreme in the PC community. First she
acknowledges that vegetarians (Paranthropus robustus) died out, while
meat-eaters thrived. But then she has to spread the PC meme: Meat is
still bad for you! Despite study after study after study that suggests
otherwise. She wouldn't even be here to write this article without the
meat-eaters, yet...

"The ancestral Australopithecus consumed a wide range of foods,
including, meat, leaves and fruits. This varied diet might have been
flexible to shift with food availability in different seasons,
ensuring that they almost always had something to eat. Paranthropus,
according to the elemental analysis, was largely a plant eater, which
matches up with previous studies of tooth morphology and wear
patterns. It also helps to explain the massive jaw structure they
possessed, which could have come in handy for tough food stuffs and
earned one specimen the nickname “nutcracker man.” Early Homo, on the
other hand, went in for a meat-heavy diet—possibly enabled by the use
of tools for hunting and butchering."
