What does it mean to be a wild animal in a world dominated by humans? A recent study found that city-dwelling raccoons’ snouts are getting shorter—a sign of domestication. Another study on dark-eyed juncos living on a Los Angeles college campus found that their beaks changed shape during the COVID-19 lockdown, when there wasn’t as much food and trash on campus.
Evolutionary biologist Pamela Yeh and animal domestication expert Raffaela Lesch join Host Flora Lichtman to discuss how wildlife is evolving in urban areas, what it means to be domesticated, and when we can expect to have a pet raccoon sleeping at the foot of the bed.
