Lab #1: Problem How is color an adaptation?

This lab we will be conducting at the end of class after we have learned some key evolutionary concepts. You need to understand all of the steps of the Scientific Method in order to be successful in your first lab!

PG 606How do scientists explain the fact that living things are well suited to where the live?

AdaptationsWhat is adaptation?

Adaptation:A trait that makes a living thing able to survive in its surrounding

Example of an adaptation: Webbing bw the toes of a bird
