The number of recognized primate species has increased dramatically in recent years (Rylands and Mittermeier, 2014).This is due to many factors, including more extensive field surveys in previously inaccessible parts of the developing world, increased sampling of genetic diversity among wild populations of primates, and changes in criteria by which species are identified (see Fleagle, 2014 … Gibbons are small, so we call them the lesser apes.
