Why Chilean Mummies Are Decomposing Afte...

About this episode
Here on Short Wave, we're getting into the Halloween spirit a little early with a look at the world's oldest mummies. They're found in modern-day northern Chile. The mummies are well-preserved, so over the past 7,000 years, some have been exhumed for scientific study. But recently, something startling happened: Some of the mummies started to decompose.

Today on the show, Regina G. Barber talks to archeologist Marcela Sepulveda about the civilization that made these mummies: the Chinchorro people. We dig into the science behind their mummification techniques and how the changing planet is affecting archeologists' ability to study the past.
