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 asynchronous course is designed to deepen educators' content knowledge in evolution, especially regarding content appropriate for teaching at the high school level.

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

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

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

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 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 animation shows how mutations can arise when DNA is damaged.

This animation explores the genetic causes and biological effects of sickle cell disease.
