Researchers reveal 2.5-million-year-old teeth of our ancestors suggest they ate GRASS

While we may enjoy a wide and varied diet, our ancient relatives may have preferred to stick to grass. Wear patterns on the fossil teeth from early East African hominids suggest that they may have eaten softer food than previously thought, according to new research. Wear patterns on the fossil teeth from East African hominims, including the Paranthropus boisei, suggest that they may have eaten softer food than previously thought Well-preserved scratch patterns has enabled the researchers to measure the markings to deduce what kind of the food the early human relatives would have eaten PARANTHROPUS BOISEI The skeleton belonged to a Paranthropus boisei hominid which lived across Africa side-by-side with direct ancestors of humans. Paranthropus boisei was a long-lived species of archaic hominin that first evolved in East Africa about 2.3 million years ago. Paranthropus boisei was a long-lived species of archaic hominin that first evolved in East Africa about 2.3 million years ago The researchers examined microscopic scratches on the cheek surfaces of teeth from 167 fossil specimens of Paranthropus and early Homo species from sites in Ethiopia, Kenya and Tanzania.
