The Problem With Superchickens

The Problem With Superchickens

Scientists recently discovered a fascinating paradox: when they bred together superproductive, egg-laying hens, they found the chickens produced fewer eggs. We examine what went wrong with these so-called superchickens, and we look at human examples of this phenomenon—a high school Model UN team and a retail giant. For more information on this episode, visit natgeo.com/overheard. Want more? David Sloan Wilson’s theories on competition and cooperation go far beyond superchickens. Take a look at an article he wrote about rethinking economics on Evonomics.com, a website started by one of his former students. And for more on his work, visit davidsloanwilson.world. Plus, retail has been through a lot over the last 50 years. To learn more about that world from the inside, check out his book, Remarkable Retail: How to Win and Keep Customers in the Age of Disruption, and his podcast, the Remarkable Retail Podcast. And read a Bloomberg article that goes into detail about what happened at Sears. Also explore: Darwin transformed the world with his evolutionary theories. He also got a lot wrong. To learn how modern science is building on his work, see our article on the subject. For subscribers: Evolution hasn’t stopped, but it is changing. Discover how humans are using technology to shape their own evolution in our article. Learn more about your ad choices. Visit podcastchoices.com/adchoices
