Bret and Heather 182nd DarkHorse Podcast Livestream: Gender Surrender

In this 182nd in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we discuss the state of the world through an evolutionary lens.Show more

In this episode we discuss the herbicide atrazine, its effects on reproductive development in amphibians, its persistence in the environment, its safety testing, and its valorization by the New York Times and the CDC. We also discuss male nipples—why do they exist?—and the CDC’s ongoing capitulation to stupid with its glossary entry on chestfeeding.
