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 video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

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 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 video shows real footage of somatic cell nuclear transfer (SCNT) being performed on eggs.

This animation gives an overview of how a fertilized human egg develops into an embryo.

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

This animation shows how zebrafish can rapidly heal wounds to the heart.

This animation shows how somatic cell nuclear transfer (SCNT) creates an embryo from an egg cell and a body cell.
