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 shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

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

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

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 video provides an overview of the types of genes that, when mutated, can lead to the development of cancer.

This film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This animation shows how a mutation that allows adult humans to digest milk can be lost or spread under different circumstances.

This animation shows how HIV infects a cell and replicates itself using reverse transcriptase.

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

This animation shows how mutations can arise when DNA is damaged.
