Hello, everybody. Welcome to a new episode of The Decenter. I'm your host, as always, Ricardo Lopes, and today I'm joined by Dr. Erica Cartmill. She's professor of cognitive science, anthropology, and animal behavior at Indiana University. She studies the acquisition and evolution of human language.

So, Doctor Cart Mill, welcome to the show. It's a pleasure to everyone. Thank you so much, Ricardo. I really appreciate your inviting me on.
