This podcast episode explores the fascinating phenomenon of pruney fingers, unraveling the scientific mechanisms behind their wrinkling, which involve vasoconstriction, and discussing their possible evolutionary advantages. While there is compelling evidence supporting the idea that pruney fingers enhance grip in wet conditions, the hosts engage in a thought-provoking debate on whether this feature is a true adaptation or simply a byproduct of biological processes, ultimately highlighting that the underlying reasons for finger pruniness remain a complex and unresolved mystery.
