In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

This animation shows how disrupting cellular processes in the intestines can lead to colon cancer.

This film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

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 zebrafish can rapidly heal wounds to the heart.

This tutorial describes the various forms of “fat” — from a tissue, to a cell type, to a class of molecules.

This tutorial explores how fat is digested, transported, stored, and used for energy.

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