A small number of lizards are introduced to an island. Their native habitat is a forest and they mostly live in trees. The island has few trees and the lizards spend most of their time on the ground where they are eaten by snakes. Over many generations the island population of lizards develop shorter toes and longer legs which allow them to run faster on bare ground. The lizards withe longest legs/shortest toes are the least likely to be caught be snakes. After several decades lizards are collected from the island and placed in enclosures. Lizards from the original forest habitat are placed in identical enclosures. Each type of lizard mates and has offspring. The offspring resemble their parents and the offspring of island lizards have shorter toes/longer legs than offspring of forest lizards (i.e the differences you see in nature are also found in a lab setting). This is an example of Group of answer choices a. both natural selection and evolution b. evolution only c. natural selection only
