Define Evolution
Change in traits of a species/ population over time

What is natural selection?
Survival of the fittest- organisms that have a favorable trait survive to reproduce

Cross breeding between brown and white rabbits in a forest produced some rabbits that had both brown and white fur, which made it easier to hide from predators during the winter. Over time, most rabbits in the forest were born with this type of coloring. What biological concept is described in this example?
Natural Selection

wing of a hawk, wing of a butterfly

4. The example of the peppered moths living near English industrial cities demonstrates that:
a.a change in an environment can result in the evolution of species living there
b.evolution occurs so slowly that it is not possible to determine that it has happened in less than a million years
c.the environment near industrial cities have always favored dark colored moths
a. a change in the environment can result in the evolution of species living there
