Extinct Species of Early Human Survived On Grass Bulbs, Not Meat
Philip Ross writes "Fresh analysis of an extinct relative of humans suggests our ancient ancestors dined primarily on tiger nuts, which are edible grass bulbs, settling a discrepancy over what made up prehistoric diets. According to a new study published in the journal PLOS One, the strong-jawed ancient hominin known as Paranthropus boisei, nicknamed 'Nutcracker Man,' which roamed East Africa between 2.4 million and 1.4 million years ago, survived on a diet scientists previously thought implausible."
The paleo movement is frustrating for anthropologists. Humans ate pretty much whatever they could get their grubby little hands on: meat, nuts, edible leaves, roots, fruit, etc. We did eat quite a bit of plants, though. Mostly because they didn't run away.
Vegans who insist we're herbivores are equally frustrating, however.
A somewhat minor nitpick, but...
It is generally thought that Paranthropus bosei is an /offshoot/ of the line that ultimately led to modern man, not a direct ancestor. We share ancestors, but do not descend from his line. The two lines diverged about 3 million years ago to follow their own evolutionary paths - homo towards an omnivorous diet and world domination, panthropus to munching on nuts and extinction.
He was a relative, not an ancestor.
You can get B12 from fermented foods, milk products, eggs, and algae. In fact, it's not even produced by animals, only by bacteria.
B12 is produced by bacteria in fermentation tanks and then ends up in tablets for vegans to eat, and in animal feed for farm animals to eat. The B12 you get from meat comes from the same exact place as the stuff in tablets.
There are actually no essential nutrients created by animals.
