Natural Selection

What does survival of the fittest mean?

• If you can bench press more weight you will survive

• The animals better adapted to an environment will survive

• Bigger animals have a better chance of surviving

Who came up with the theory of evolution?

• Charles Darwin

• Gregor Mendel

• Watson and Crick

• Rosalind Franklin

How did the dark mice appear in the desert?

• The light mice decided to be dark to blend in with the dark rocks

• The dark mice moved from a different area

• A random mutation caused darker fur color

• The dark mice are really light mice that are dirty

Why was there a decrease of light mice and increase in dark mice in DARKER areas?

• The light mice moved away

• The dark mice survived and reproduced while light were eaten

• Light mice survived and reproduced more

• It was just by chance

What was the driving environmental force that caused the increase in dark mice in darker areas over time?

• Predators ate the light mice because they were easy to see and the dark mice survived

• The mice decided to change colors

• More dark mice moved to the area

If there was an increase in lighter areas, what would you expect the mouse population to look like?

• More dark mice

• Less dark mice

• More light mice

• Less light mice

Mutations can be... (check all that apply)

• Beneficial

• Harmful

• Neutral (no effect)

• Intentional

What is a nonsense mutation?

• Has no effect on the protein

• Stops the translation process

• Changes the amino acid produced

What is a missense mutation?

• Has no effect on the protein

• Stops the translation process

• Changes the amino acid produced

What is a silent mutation?

• Has no effect on the protein

• Stops the translation process

• Changes the amino acid produced
