Until recently, anthropologists generally agreed that higher primates originated about 30 million years ago in the Al 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
higher primates cannot be identified solely by their lower jawbones
