This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

This activity guides the analysis of a published scientific figure from a study that explored inbreeding depression in a small, isolated population of wolves.

This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.

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.

This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.

This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.

This video follows Joyce Poole and other scientists working in Gorongosa National Park, Mozambique, who made the observation that many female elephants lack tusks.

This activity guides the analysis of a published scientific figure from a study that explored how dinosaurs may have regulated their body temperatures.

This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.

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.

This interactive module explores the environmental factors and species involved in five major mass extinctions.
