This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

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 video describes how prehistoric extinction rates are calculated from fossil data in a paleodatabase and compared to modern extinction rates.

This animation shows how a single species can give rise to many different species with distinct traits, using anole lizards as an example.

This film explores four decades of research on the evolution of Galápagos finches, which has illuminated how species form and diversify.

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.

This film tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

This animation provides an overview of the greenhouse effect, a process that warms the atmosphere and surface of Earth.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

This animation shows how varying concentrations of a signaling molecule activate different transcription factors to determine cell fate.

This animation shows how stem cells from early mammalian embryos can be grown and studied in a laboratory.

This animation describes the formation and fates of the three germ layers in a human embryo.
