To mark Father's Day, Radiolab shared a special crossover episode from its nature-focused spin-off, Terrestrials, to spotlight the unusual roles of fathers in the animal kingdom.
Introducing the episode, host Lulu Miller pitched the story as a "special little meditation on dads in the animal world" designed to expand listeners' understanding of what fatherhood can look like. Rather than sticking strictly to human stories, the episode dives into the stranger corners of Earth's biology, promising a "dadventure" that bridges the gap between the two shows.
While some listeners tune in to Radiolab strictly for its traditional deep-dive journalism, this crossover demonstrates how Terrestrials is successfully establishing its own identity by bringing a lighter, more whimsical focus to the network's feed.
