=== Hybrids ===
Researchers have found that both central (''[[Central chimpanzee|Pan troglodytes troglodytes]]'') and eastern chimpanzees ([[Eastern chimpanzee|''Pan troglodytes schweinfurthii'']]) share more genetic material with bonobos than other chimpanzee subspecies.<ref>{{Cite news |last=Owens |first=Brian |date=2016-10-27 |title=Chimps and bonobos interbred and exchanged genes |work=New Scientist |url=https://www.newscientist.com/article/2110682-chimps-and-bonobos-interbred-and-exchanged-genes/ |access-date=2022-04-06 |archive-date=2022-01-28 |archive-url=https://web.archive.org/web/20220128162354/https://www.newscientist.com/article/2110682-chimps-and-bonobos-interbred-and-exchanged-genes/ |url-status=live }}</ref> It is believed that [[genetic admixture]] has occurred at least two times within the past 550,000 years.<ref>{{Cite web |date=2022-04-06 |title=Ancient interbreeding between chimpanzees and bonobos |url=https://cnag.crg.eu/news/ancient-interbreeding-between-chimpanzees-and-bonobos |access-date=2022-04-06 |website=cnag.crg.eu |archive-date=2020-12-31 |archive-url=https://web.archive.org/web/20201231062259/https://www.cnag.crg.eu/news/ancient-interbreeding-between-chimpanzees-and-bonobos |url-status=dead }}</ref> In modern times hybridization between bonobos and chimpanzees in the wild is prevented as populations are [[Allopatric speciation|allopatric]] and kept isolated on different sides of the Congo river.<ref>{{Cite web |last=Jewett |first=Katie |date=2017-04-25 |title=The Great Divide |url=https://www.biographic.com/the-great-divide/#:~:text=The%20Congo%20River%20separates%20the,this%2C%20the%20world's%20deepest%20river. |access-date=2022-04-06 |website=www.biographic.com |archive-date=2022-05-23 |archive-url=https://web.archive.org/web/20220523204316/https://www.biographic.com/the-great-divide/#:~:text=The%20Congo%20River%20separates%20the,this%2C%20the%20world's%20deepest%20river. |url-status=live }}</ref>

Within captivity, hybrids between bonobos and chimpanzees have been recorded. Between 1990 and 1992, five pregnancies were conceived and studied between a male bonobo and two female chimpanzees. The two initial pregnancies were aborted because of environmental stressors. The following three pregnancies however led to the birth of three hybrid offspring.<ref>{{Cite journal |last1=Vervaecke |first1=Hilde |last2=Elsacker |first2=L. van |date=1992 |title=Hybrids between common chimpanzees (Pan troglodytes) and pygmy chimpanzees (''Pan paniscus'') in captivity |journal=Mammalia |volume=56 |issue=4 |pages=667–669 |issn=1864-1547 |access-date=2023-12-01 |url=https://www.researchgate.net/publication/272356540 |archive-date=2024-03-09 |archive-url=https://web.archive.org/web/20240309175202/https://www.researchgate.net/publication/272356540_Hybrids_between_common_chimpanzees_Pan_troglodytes_and_pygmy_chimpanzees_Pan_paniscus_in_captivity |url-status=live }}</ref>

A bonobo and chimpanzee hybrid called Tiby was also featured in the 2017 Swedish film ''[[The Square (2017 film)|The Square]]''.<ref>{{Cite book |last=Foundation |first=Arcus |title=Killing, Capture, Trade and Ape Conservation: Volume 4 |publisher=Cambridge University Press |date=2021-04-29 |isbn=9781108487948 |pages=111}}</ref> This same male bonobo and female chimpanzee had several offspring.<ref>Bonobo-chimpanzee Hybrids, Pan paniscus × Pan troglodytes, "EUGENE M.
