This episode \u2014first released in 2009 and then again in 2015, with an update \u2014 asks, what is \u201cnormal\u201d? Maybe it exists, maybe not. We examine peace-loving baboons with Stanford neuroscientist Robert Sapolsky, talk to Stu Rasmussen, whose preferred pronouns were he/him (https://zpr.io/nUdsZawNmhwt), and his neighbors in Silverton, Oregon about how a town chooses its community over outsider opinions. And lastly, we speak with an evolutionary anthropologist, Duke University\u2019s own Brian Hare, and an evolutionary biologist Tecumseh Fitch, then at the University of St. Andrews, Scotland, now at the University of Vienna, Austria, about foxes who love to snuggle.And what we find is that normal \u2014 maybe the only normal \u2014 is change.\nEPISODE CREDITS\xa0Reported by - Aaron CohenProduced by - Soren Wheelerwith help from - Annie McEwenCITATIONSArticles -Stu Rasmussen\u2019s NYT Obituary (https://zpr.io/nUdsZawNmhwt).\nTheater -\xa0Andrew Russel\u2019s \u201cStu for Silverton\u201d (https://zpr.io/Jn5JP276pwhj) the play based on Stu Rasmussen\u2019s life.\xa0\n\xa0\nOur newsletter comes out every Wednesday.
