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."
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.
