117: Bonobos and chimps show 'a rich recognition' for long-lost friends and family

Bonobos and chimpanzees — the closest extant relatives to humans — could have the longest-lasting nonhuman memory, a study led by a UC Berkeley researcher found. Extensive social memory had previously been documented only in dolphins and up to 20 years."What we're showing here," said Berkeley comparative psychologist Laura Simone Lewis, "is that chimps and bonobos may be able to remember that long — or longer."Berkeley News writer Jason Pohl first published a story about this study in December 2023. We used his interview with Lewis for this podcast episode.Photo courtesy of Laura Simone Lewis.Music by Blue Dot Sessions.Listen to the episode and read the transcript on UC Berkeley News (news.berkeley.edu/podcasts).
