How did the ancestors of modern horses differ from today's horses?

• They were larger and had hooves.

• They were smaller and had distinct toes.

• They had wings.

• They were aquatic.

What advantage do taller giraffes have over shorter ones?

• They can run faster.

• They can reach higher leaves for food.

• They are more colorful.

• They have better camouflage.

Why did the brown beetle population increase over generations?

• They had more offspring.

• They were more attractive to mates.

• They had a better camouflage on the brown table.

• They were faster than green beetles.

What was the initial allele frequency for light brown and black fur mice?

• 0.3 for light brown, 0.7 for black

• 0.9 for light brown, 0.1 for black

• 0.5 for both

• 0.7 for light brown, 0.3 for black

What is the main reason light brown fur mice became more common?

• They were more aggressive.

• They were larger in size.

• They had better camouflage against predators.

• They reproduced faster.

What is the primary mechanism discussed that leads to evolution?

• Mutations

• Natural selection

• Genetic drift

• Gene flow

What happens to traits that are not beneficial for survival?

• They decrease in frequency.

• They become dominant.

• They remain unchanged.

• They become more common.

What is the outcome for organisms that cannot survive in their environment?

• They become the dominant species.

• They are unlikely to reproduce and pass on their genes.

• They migrate to a new environment.

• They thrive and reproduce.
