This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This interactive module explores how CRISPR-Cas9 technology works and the many ways in which scientists are using it in their research.

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

A number of interactive questions are embedded within the short film The Making of the Fittest: Evolving Switches, Evolving Bodies, which illustrates how mutations in gene regulatory regions can result in the evolution of major anatomical features.

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 interactive questions are embedded within the short film The Biology of Skin Color, which explores the hypothesis that the variations in skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

A number of questions are embedded within the short film Popped Secret: The Mysterious Origin of Corn, which explores the genetic and archaeological evidence that corn was domesticated from a wild Mexican grass called teosinte.

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.
