This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

This film explores the evolutionary connection between an infectious disease, malaria, and a genetic condition, sickle cell disease.

This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.

This film describes the scientific principles and the research efforts involved in the development of a gene therapy for a congenital form of blindness, and how a young patient benefited from this medical breakthrough.

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

This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

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 transcription factors find their binding sites in real time. It is based on data from an imaging method that can track single molecules in a living cell.

This film explores how mutations in gene regulatory regions have resulted in major changes in the anatomy of freshwater populations of stickleback fish.

This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

This film explores the genetics and evolution of lactase persistence in humans.

This animation shows how a variety of proteins interact to regulate the transcription of eukaryotic DNA into RNA.
