Classroom Cladogram of Vertebrate/Human Evolution

Bring together a study of two major scientific topics with a activity on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn how...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Vision is arguably the most important of the five senses, but exactly how did we come by this amazing ability?  Find out with this engaging video on the 500 million year evolution of the human eye.

Can humans be infected by animal viruses? Pupils explore the phenomenon of viral evolution and learn about how animal viruses sometimes adapt to infect humans. They see how viruses are transmitted and what pathogens need to survive. The...

The featured movie focuses on the ancestry of our four-footed friends. Find the fundamental pattern of their limbs and vertebrae in fossils of fish. After viewing, biology learners can enjoy interactive websites to zoom in on the...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

Learners transfer examples (names) of primates from their location in an outline hierarchy of primate groups into a set of nested boxes reflecting that same hierarchy. A cladogram can then be drawn illustrating how these groups are...

Some species of fish are more closely related to humans than they are to other species of fish! How did so many species, that aren't closely related, develop the same body shape? A short video explains the evolution of fish. 

Learners explore the major characteristics of the major animal phyla. They describe adaptive features that have contributed to the success of animals on land. Students explain how primate evolution provides a context for understanding...
