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

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

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

This hands-on activity supports concepts covered in the film Evolving Switches, Evolving Bodies about the evolution of stickleback fish. Students interpret molecular diagrams and build physical models of eukaryotic gene regulation.

This animated short video tells the story of the discovery of the coelacanth, a species that belongs to a group of lobe-finned fish that existed 400 million years ago.

This interactive module allows students to examine fossils of fish, tetrapods (four-limbed animals), and their transitional forms.
