The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture
Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

The Making of the Fittest: Natural Selection and Adaptation
The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

Got Lactase? The Co-Evolution of Genes and Culture
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

The Case of Darwin's Finches
One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...
