Macaque China reported in the journal "Cell" the creation of two crab-eating macaque monkey clones, named "Zhong Zhong" and "Hua Hua", using the complex DNA transfer method that produced "Dolly" the sheep, for the first time. As of 2005, the authors of "Mammal Species of the World" recognized the following species and species groups, aside from the white-cheeked macaque which was described in 2015: Later studies disputed some of the species groupings. For example, Li, "et al", based on DNA testing, do not recognize the "M. fascularis" group. Rather, they place the crab-eating macaque within the "M. mulatta" group and the
Macaque and have become an invasive species in some human inhabited landscapes, such as the island of Mauritius and Silver Springs State Park in Florida. Macaques can be a threat to conservation, along with a threat to human wellbeing through carrying transmittable and fatal diseases. Currently, macaques as an invasive species are handled with several control methods. Aside from humans (genus "Homo"), the macaques are the most widespread primate genus, ranging from Japan to the Indian subcontinent, and in the case of the barbary macaque ("Macaca sylvanus"), to North Africa and Southern Europe.
