The Making of the Fittest: Evolving Switches and Evolving Bodies

This is award-winning short film with transcript. Summary: Watch this film to learn about a species where we can study evolution in action, identify key genes, and peer deep into the evolutionary past. Stickleback bodies have undergone a dramatic transformation, some populations completely losing long projecting body spines that defend them from large predators. Various scientists, including David Kingsley and Michael Bell, have studied living populations of threespine sticklebacks, identified key genes and genetic switches in the evolution of body transformation, and even documented the evolutionary change over thousands of years by studying a remarkable fossil record from the site of an ancient lake ten million years ago.
