Muna-Buton macaque Muna-Buton macaque The Muna-Buton macaque ("Macaca ochreata brunnescens") is one of seven Sulawesi macaques in Indonesia. It is only found on two small islands off the south-east coast; the islands of Buton and Muna. This Old World monkey is diurnal and arboreal, although it can spend significant amounts of time on the ground. It is black with grey "boots" and a brownish colour to the fur on its back. Like other Sulawesi macaques it has a reduced tail of only about 35mm in length. Its body is about 475 - 495mm in length. The Muna-Buton macaque feeds on fruits for
Rhesus macaque The X chromosome has three times more rearrangements than other chromosomes. The macaque gained 1,358 genes by duplication. Triangulation of human, chimpanzee, and macaque sequences showed expansion of gene families in each species. The "PKFP" gene, important in sugar (fructose) metabolism, is expanded in macaques, possibly because of their high-fruit diet. So are genes for the olfactory receptor, cytochrome P450 (which degrades toxins), and CCL3L1-CCL4 (associated in humans with HIV susceptibility). Immune genes are expanded in macaques, relative to all four great ape species. The macaque genome has 33 major histocompatibility genes, three times those of human. This has clinical
