Tibetan macaque Tibetan macaque The Tibetan macaque ("Macaca thibetana"), also known as the Chinese stump-tailed macaque or Milne-Edwards' macaque, is found from eastern Tibet east to Guangdong and north to Shaanxi in China. It has also been reported from northeastern India. This species lives in subtropical forests (mixed deciduous to evergreen) at altitudes from above sea level. There are four recognized subspecies: The Tibetan macaque is the largest species of macaque and one of the largest monkeys found in Asia. Only the proboscis monkey and the larger species of gray langur come close to match their size among Asian monkeys. Males are
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
