This activity explores the content and research presented in the documentary film series Your Inner Fish, which describes major transitions in the evolution of vertebrate animals, including humans.

This film explores how the genetic and anatomical legacy of a fish can be seen today in the human body.

This film explores what our hair, teeth, and hearing reveal about our evolution from ancient reptilian ancestors.

This film explores what human hands, vision, and brains reveal about our evolution from ancient primate ancestors.

This interactive module explores different anatomical features of the human body and what they reveal about the evolutionary history of humans.

This video shows the reactions of first-grade students to a replica of a Tiktaalik fossil.

This animated short video tells the story of the discovery of the coelacanth, a species that belongs to a group of lobe-finned fish that existed 400 million years ago.

This video provides an introduction to the stickleback fish and their predators, which live in freshwater lakes.

This hands-on activity supports concepts covered in the film Evolving Switches, Evolving Bodies about the evolution of stickleback fish. Students interpret molecular diagrams and build physical models of eukaryotic gene regulation.

This animation shows how changes in the regulatory switch regions of the Pitx1 gene lead to morphological differences in stickleback fish.

This activity guides the analysis of a published scientific figure from a study that tested how individual fish responded to an artificial model of a fish school.

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.
