===Hybrids===
Primate [[Hybrid (biology)|hybrids]] usually arise in captivity,<ref name="songs">{{cite journal |title=Songs of hybrid gibbons (''Hylobates lar'' × ''H. muelleri'') |author=Tenaza, R. |year=1984 |journal=American Journal of Primatology |volume=8 |issue=3 |pages=249–253 |doi=10.1002/ajp.1350080307|pmid=31986810 |s2cid=84957700 }}</ref> but there have also been examples in the wild.<ref name="natoccur">{{cite journal |year=1966 |title=Naturally occurring primate hybrid |author=Bernsteil, I.

Although they belong to genera that have been distinct for several million years, interbreeding still occurs between the [[gelada]] and the [[hamadryas baboon]].<ref>{{cite journal |last1=Jolly |title=Intergeneric Hybrid Baboons |journal=International Journal of Primatology |year=1997 |volume=18 |issue=4 |doi=10.1023/A:1026367307470 |pages=597–627 |first1=C.
