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.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.

This interactive module allows students to compare the morphological characteristics of seashells and construct an evolutionary tree.

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

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

This playlist can be used to teach several core topics in evolution by exploring examples of lizard species evolution and the effects of mass extinctions on tetrapod evolution. It can be used in undergraduate biology courses.

This playlist can be used in an online, undergraduate (majors-level) introductory biology lab to incorporate core topics in evolution, diversity of life, and ecology.

This playlist can be used to teach several core concepts of natural selection and speciation by connecting students to actual research on Caribbean anoles. It can be used in AP/IB Biology and undergraduate college courses.
