Summary

You can learn a lot about ocean health from seabirds. For example, breeding failures among certain birds have been linked to the later collapse of some fisheries. Enriqueta Velarde of the Institute of Marine Sciences and Fisheries at the University of Veracruz in Xalapa, Mexico, joins host Sarah Crespi to talk about what these long-lived fliers can tell us about the ocean and its inhabitants. Also this week, Sarah and Cathal O’Madagain of the Ecole Normale Supérieure in Paris discuss pointing—a universal human gesture common to almost all children before age 1. They discuss why pointing matters, and how this simple gesture may underlie humans’ amazing ability to collaborate and coordinate. This week’s episode was edited by Podigy.
