This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

This animation illustrates the main stages of the water cycle in Gorongosa National Park, an ecosystem that experiences both wet and dry seasons.

This film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte.

This animation shows how a single species can give rise to many different species with distinct traits, using anole lizards as an example.

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.

This film explores four decades of research on the evolution of Galápagos finches, which has illuminated how species form and diversify.

This video explores how people developed the different breeds of dogs that exist today through selective breeding.

This animation shows how the protein MECP2 helps switch off gene expression.

This animation shows how X chromosomes are randomly switched off in most female mammals.
