《梳毛、八卦及语言的进化》 / Grooming, Gossip and the Evolution of Language

[[GroomingGossipAndEvolutionOfLanguage|《梳毛、八卦及语言的进化》]] is the [[RobinDunbar|Robin Dunbar / 罗宾·邓巴]] book discussed in 83.梳毛、八卦及语言的进化：人际关系“邓巴数”，咱不服不行. In the episode’s presentation, the book argues that language did not arise only for hunting, myth, instruction, or abstract information transfer; it also arose because larger human groups needed a scalable substitute for one-to-one social grooming.

The source treats the book as a bridge between evolutionary psychology and ordinary life. It moves from primate grooming and [[DunbarNumber|Dunbar Number / 邓巴数]] into office chatting, gendered conversation hypotheses, dialects and slang, religion, art, internet communication, and [[PodcastIntimacy|podcast intimacy]].

• Language can replace some grooming because it lets one speaker include several listeners at once.
• Gossip and small talk are socially functional even when they carry little formal information.
• The book’s appeal in the episode comes from making daily behavior legible without reducing people to simple instincts.
