Red Tattoo

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.

Diving Adaptations in Sea Nomads

This activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

Coloration in Vertebrates

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

Skin Color and Human Evolution

This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

New Laetoli Footprints and Hominin Body Size

This activity guides the analysis of a published scientific figure from a study that used footprints formed millions of years ago to estimate the heights of early human ancestors.

Patterns in the Distribution of Lactase Persistence

This activity extends concepts covered in the film Got Lactase? The Co-Evolution of Genes and Culture. Students analyze data from the scientific literature to draw conclusions about the geographic distribution of lactase persistence.

Understanding Variation in Human Skin Color

In this activity, students extend the concepts covered in the short film The Biology of Skin Color through the application of models and mathematical thinking to explain how genomic variation and human ancestry can explain differences in skin color, a polygenic trait.

Zebrafish and Skin Color

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.

Amylase Copy Number and Diet

This activity guides the analysis of a published scientific figure from a study that investigated whether there is a correlation between a population’s diet and copies of a certain gene.
