How human intervention is creating a new urban species

75ft Above NYC: Redesigning the Modern Chicken | Part 2 | SLICE EARTH · 11:28 · Video: SLICE Earth · Watch at the source

In short: High above the industrial sprawl of Queens, chickens are adapting to a radical new ecosystem. This video explores how selective breeding and anthropogenic forces are transforming the domestic chicken into a distinct urban bird.

The documentary examines the evolution of Gallus gallus domesticus through human-led manipulation of morphology. From high-stakes social hierarchies in Brooklyn Grange to European genetic laboratories, experts use selective breeding to create hyper-specialized results, such as Bantam breeds and record-breaking vocalists capable of 21-second crows.

By analyzing 13,000 specimens from the European Poultry Show, the film documents how human intervention has pushed these birds into a new era of biological diversity. It highlights the shift from traditional backyard farming to a sophisticated, anthropogenic redesign of one of the world's most diverse avian species.
