[2] The greeting behaviour is generally carried out by the approaching monkey and often is followed with grooming. Recent work on four Rhinopithecus species, including the GSM, shows that these colobines possess derived genetic adaptations associated with an efficient ability to metabolize fatty acids and xenobiotics and to enable the digestion of high levels of RNA derived from their stomach microbiome.
