This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

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

A number of questions are embedded within the short film The Origin of Species: The Beak of the Finch, which explores four decades of research on the evolution of the Galápagos finches.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

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

This tutorial describes the principles of DNA sequencing and sequence assembly, and shows how they apply to different sequencing techniques.

This tutorial describes how DNA microarrays called Virochips are designed to detect known viruses and discover new ones.

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

This tutorial explains how scientists analyze and interpret the large data sets generated by DNA microarrays.

This interactive, modular lab explores the techniques used to identify different types of bacteria based on their DNA sequences.
