Human ancestors like Australopithecus – which lived around 3.5 million years ago in southern Africa – ate very little to no meat, according to new research published in the scientific journal Science. This conclusion comes from an analysis of nitrogen isotope isotopes in the fossilized tooth enamel of seven Australopithecus individuals. The data revealed that these early hominins primarily relied on plant-based diets, with little to no evidence of meat consumption.

Better graph. The only data I've seen on modern brain size differences would be due to vitamin deficiencies.
