Evolution Quiz

What best explains why species are often adapted to their environment?

• The traits in a population randomly change.

• Species evolve new traits through mutation.

• Species study their environment and learn the best way to survive.

• Members of a population with adaptive traits are more likely to survive and reproduce than the rest of the population.

According to the model, how are humans driving the evolution of antibiotic-resistance in bacteria?

• Antibiotics are a selective pressure that favor resistant bacteria.

• Sensitive bacteria mutate slower inside the human body.

• Lots of humans are getting sick.

• Humans produce food that cause antibiotic resistance.

Research shows that cheetahs have extremely low genetic diversity. What is the significance of this finding?

• Cheetahs are at high risk of extinction if the environment changes.

• Cheetahs will be able to survive multiple changes to the environment.

• Cheetahs will evolve through natural selection.

• Cheetahs have a lot of different mutations.

Giraffes today have long necks. However, the ancestors of giraffes all had short necks. Which event must have happened first during the evolution of the giraffe?

• A mutation created giraffes with long necks.

• Long-necked giraffes migrated to different countries.

• Long-necked giraffes were more likely to survive and reproduce than short-necked giraffes.

• The genetic diversity of giraffes decreased.

Predict how the high mutation rates of bacteria contribute to their genetic diversity.

• High mutation rates lead to identical genetic makeup in bacteria.
• High mutation rates have no impact on genetic diversity in bacteria.
• High mutation rates increase their genetic diversity by introducing new genetic variations.

• High mutation rates decrease genetic diversity by limiting variations.
