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 film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

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 provides an overview of the greenhouse effect, a process that warms the atmosphere and surface of Earth.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

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.
