This animation shows how disrupting cellular processes in the intestines can lead to colon 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 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 four decades of research on the evolution of Galápagos finches, which has illuminated how species form and diversify.

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

This animation shows how human infants can digest milk using the enzyme lactase.

This animation shows how varying concentrations of a signaling molecule activate different transcription factors to determine cell fate.

This animation shows how stem cells from early mammalian embryos can be grown and studied in a laboratory.

This animation describes the formation and fates of the three germ layers in a human embryo.

This animation shows how salamanders can replace missing limb tissues with the help of cells similar to stem cells.

This animation shows how the PPAR-gamma receptor can activate fat storage and changes in hormone levels.

This animation shows how tumors use the protein VEGF to recruit blood vessels.
