Until recently, scientists assumed humans were the only species in which females went through menopause, and lived a substantial part of their lives after they were no longer able to reproduce. And they had no idea why that happens, and why evolution wouldn’t push females to keep reproducing right up to the end of their lives. But after a close look at some whale poop, and a deep dive into chimp life, we find several new ways of thinking about menopause and the real purpose of this all too often overlooked second act of life.  Special thanks to Danielle Friedman, Rachel Gross, and Kate Radke.EPISODE CREDITS: Reported by - Heather Radke and Becca BresslerProduced by - Sarah Qari and Becca BresslerFact-checking by - Emily Kriegerand Edited by  - Becca BresslerEPISODE CITATIONS:Books - Check out everything Heather Radke writes, including Butts: A Backstory, cause it’s all that good, here: Heather Radke (www.heatherradke.com).Find any one of Lucy Cooke’s book, including Bitch:On the Female of the Species, here: L
