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
