Chapter 12, Problem 8WIO

Summary Introduction

To determine:

The mode of natural selection in which Green Fraggles become visible due to dust storm to Gorgs, who tend the gardens and try to kill the Green Fraggles, whereas gray Fraggles blend easily into the dusty background, how these event will affect evolution in the Fraggles.

Concept introduction:

A dust storm blankets the green garden of the Fraggles in gray. The green Fraggles, therefore, become visible to the Gorgs, who tend the gardens and try to kill the Fraggles to protect their crop. The gray Fraggles, however, blend easily into the dusty background. These events will evolve the gray Fraggles and mode of natural selection in directional selection.
