Our early ancestors, living in what is now northern Kenya, feasted on fish and other aquatic animals such as turtles and crocodiles - foods which probably played a major role in the development of a larger, more human-like brain, new research reveals.It takes quite a bit of intelligence to incorporate all of those different kinds of foods into a single diet. It is always interesting to see a report like this that basically ends "they were smarter than we thought."
The study, which offers the first-ever evidence of dietary variety among early pre-humans, appears in Proceedings of the National Academy of Sciences. A team of researchers that included Johns Hopkins University geologist has found that early hominids living in what is now northern Kenya ate a wider variety of foods than previously thought, including fish and aquatic animals such as turtles and crocodiles. Rich in protein and nutrients, these foods may have played a key role in the development of a larger, more human-like brain in our early forebears, which some anthropologists believe happened around 2 million years ago, according to the researchers’ study.
