This activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.

This activity explores images of animals with a mutation that affects coloration, which serve as phenomena for learning about skin color genetics and evolution.

In this activity, students explore how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color. The activity complements the film The Biology of Skin Color.

In this case study, students use real data to propose hypotheses, make predictions, and justify claims with evidence, as an exploration of concepts presented in the short film The Biology of Skin Color.

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 the different gaits employed by animals and how the nervous system is able to switch between gaits.

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