That's an opinion piece from the Huffington Post. Is that more credible than legitimate scientific sources? Nah, I don't think so.
Eating Meat Made Us Human, Suggests New Skull Fossil
Eating Meat Made Us Human, Suggests New Skull Fossil
Fragments of a 1.5-million-year-old skull from a child recently found in Tanzania suggest early hominids weren't just occasional carnivores but regular meat eaters, researchers say.
The finding helps build the case that meat-eating helped the human lineage evolve large brains, scientists added.
"I know this will sound awful to vegetarians, but meat made us human," said researcher Manuel Domínguez-Rodrigo, an archaeologist at Complutense University in Madrid.
Sorry, vegans: Eating meat and cooking food is how humans got their big brains
Sorry, vegans: Eating meat and cooking food is how humans got their big brains
Vegetarian, vegan and raw diets can be healthful, probably far more healthful than the typical American diet. But to call these diets “natural” for humans is a bit of a stretch in terms of evolution, according to two recent studies.
Eating meat and cooking food made us human, the studies suggest, enabling the brains of our prehuman ancestors to grow dramatically over a few million years.
Although this isn’t the first such assertion from archaeologists and evolutionary biologists,
the new studies demonstrate that it would have been biologically implausible for humans to evolve such a large brain on a raw, vegan diet and that meat-eating was a crucial element of human evolution at least a million years before the dawn of humankind.

Meat eating behind evolutionary success of humankind, global population spread, study suggests
Carnivory is behind the evolutionary success of humankind. When early humans started to eat meat and eventually hunt, their new, higher-quality diet meant that women could wean their children earlier. Women could then give birth to more children during their reproductive life, which is a possible contribution to the population gradually spreading over the world. The connection between eating meat and a faster weaning process is shown by a research group from Sweden, which compared close to 70 mammalian species and found clear patterns.
You were evolved to be a herbivore whether you like it or not.
