Barbary macaque and exclusion of monkeys from water sources are major causes of cedar bark stripping behaviour in Barbary macaques. Density of macaques, however, is less correlated with the behaviour than the other causes considered. The Barbary macaque was named by Carl Linnaeus in 1758, along with numerous other species named in that same year. The scientific name is "Macaca sylvanus". Phylogenetic and molecular analysis with other primates has been done. Studies concerning interspecific DNA variation within the genus "Macaca" show that the Barbary macaque is most related to the Asian macaques. Scientists have also studied the Y-chromosome; however, this has proven
Arunachal macaque and 3500 m above sea level, making it one of the highest-dwelling primates. It belongs to the "M. sinica" species-group of macaques, along with the Assamese macaque ("M. assamensis"), the Tibetan macaque ("M. thibetana"), the bonnet macaque ("M. radiata") and the toque macaque ("M. sinica"). The Arunachal macaque is apparently physically similar to the Assam and Tibetan macaques, while genetically closely related to the bonnet macaque of southern India. This is probably the result of convergent evolution, where organisms evolve similar physical features due to similar environmental selection pressure, while genetically they may have different origins. However, its full specific
