单项选择题

Until recently, anthropologists generally agreed that higher primates originated about 30 million years ago in the A1 Fayyum region of Egypt. However, a 40-million-year-old fossilized fragment of a lower jawbone discovered in Burma (now called Myanmar) in 1978 was used to support the theory that the earliest higher primates originated in Burma. However, the claim is premature for______.
Which one of the following, if true, is the most logical completion of the paragraph above

A．there are no more primate species in Burma than there are in Egypt

B．several anthropologists using different dating methods, independently confirmed the estimated age of the jawbone fragment

C．higher primates cannot be identified solely by their lower jawbones

D．several prominent anthropologists do not believe that higher primates could have originated in either Egypt or Burma

E．(E) other archaeological expeditions in Burma have unearthed higher-primate fossilized bone fragments that are clearly older than 40 million years
