This interactive module allows students to examine fossils of early humans and compare them to modern primates.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

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

This interactive module explores different anatomical features of the human body and what they reveal about the evolutionary history of humans.
