Arunachal macaque status is not beyond doubt and further research might show it to be a new subspecies of Assamese or Tibetan macaques. This monkey is severely persecuted in some parts of its known distribution by locals retaliating against crop raiding. Recent surveys suggest that this species may be highly endangered in some parts of Arunachal Pradesh. Arunachal macaque The Arunachal macaque ("Macaca munzala"), a relatively large brown primate with a comparatively short tail, is a macaque native to Arunachal Pradesh in northeastern India. Its species name comes from "munzala" ("monkey of the deep forest") as it was called by the Dirang
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
