Phylogeny and Classification of Gibbons (Hylobatidae)in studies on wild and captive gibbons in the past decade, our knowledge on this enigmatic primate group has increased tremendously. Accordingly, we learned that the gibbon family is more diverse than previously known even just two decades ago. Today, four genera, 19 species and a total of 25 taxa a
