How did the drive to reproduce unlock the incredible beauty and complexity of life on Earth? Official website: https://to.pbs.org/4sE152j #novapbs Sex changed everything—evolutionarily speaking, that is. By shuffling the genetic deck it unleashed variation, fueling diversity and throwing evolution into overdrive. But how did this radical innovation begin? From the first exchange of genes to the origins of males and females, uncover the evolutionary leaps that reshaped life. Follow the evolution of the ostrich to reveal how the egg became a breakthrough that allowed life to conquer land—and how feathers transformed into tools of courtship before they were ever used for flight. #evolution #mating #reproduction © 2026 WGBH Educational Foundation All rights reserved This program was produced by GBH, which is solely responsible for its content.
