In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

It doesn't matter if you look on land, in the air, underground, or in water—evolution is everywhere. Scholars complete worksheets with multiple question types as they progress through six online missions creating phylogenic trees. 

On the Caribbean islands, lizards expanded into different niches instead of competing for resources. Scholars discuss and learn from experts in a video how scientists prove the theory. They build phylogenetic trees based on appearances...

Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...

This is a lesson designed by a biology teacher. In it, students use maps and evidence of island age, molecular genetics, morphology, and distance apart to determine how the islands came to be occupied by different species of lizards. It...

Good visual site from PBS that presents the geologic history of sharks and acts a good introduction.
