At least nine fossilized teeth, one canine tooth and eight molars, of a previously unknown species of apes found in Africa were discovered by a team of researchers from Ethiopia and Japan who then compared the 3-D make up of the teeth to other fossils that date back as far as 8 million years and found that the fossils are likely a "direct ancestor" of apes currently living in Africa and that the new ape fossils were that of a species of gorilla who ate mostly plants high in fiber.
アフリカで発見されたこれまで未知の種の類人猿の少なくとも9本の化石化した歯、うち1本は犬歯、8本は臼歯が、エチオピアと日本の研究者チームに発見され、彼らは次にその歯の3D構造を800万年前にさかのぼる他の化石と比較し、その化石は現在アフリカに住んでいる類人猿の「直接の祖先」である可能性が高く、新たな類人猿の化石は繊維質の多い植物を主に食べていたゴリラの種の歯であることを発見した。
