Fish Origins Revealed in DNA
In this episode, we’re investigating the origins of Hawaiian reef fishes with Dr. Brian Bowen’s lab at the Hawai‘i Institute of Marine Biology. The Hawaiian islands are in the middle of the Pacific Ocean Basin and far away from other coral reefs—meaning that Hawaiian reef fishes originally arrived as larvae, traveling in currents from westward in Japan or southward from the Line Islands. Dr. Bowen and his researchers are using genetic tools to uncover the mystery of where Hawaii’s reef fish came from. — Season 5, Episode 3.
