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 interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

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 video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

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 tutorial describes three examples of recent human adaptations: lactose tolerance, sickle cell disease, and bitter taste perception.

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

This tutorial describes how animals differ in their abilities to heal wounds and regenerate lost body parts or damaged tissues.
