Lesson 7

How Can We Explain How Anoles Evolved Bigger Toe Pads?

Big Idea:

The same process of natural selection applies with present-day animals – anoles – but it’s easy to misunderstand it.



Students use data from a video about anoles to test whether their natural selection model could explain how anoles got bigger toe pads. They examine statements made by other people about toe pad adaptation in anoles. If necessary, they revise the statements to align with the framework they have developed.
