Gibbon–human last common ancestor

The gibbon–human last common ancestor (GHLCA, GLCA, or G/H LCA) is the last species that the families Hominidae and Hylobatidae (i.e. the orangutan–gorilla–chimpanzee–human last common ancestor on one hand and gibbons on the other) share as a common ancestor. It is estimated to have lived 15.9 to 17.6 million years ago (T_GHLCA) during the early Miocene.
