Introduction to Evolution and Natural Selection

What is a common misunderstanding about evolution?

• Evolution requires an active decision by the organism.

• Evolution is driven by natural selection.

• Evolution happens only over millions of years.

• Evolution is a process aimed at improving species.

What does variation within a population imply?

• There are differences among individuals in a population.

• The population cannot evolve.

• The environment has no effect on the population.

• All individuals are identical.

What example is used to illustrate natural selection?

• The development of antibiotic resistance in bacteria.

• The domestication of dogs.

• The peppered moth during the Industrial Revolution.

• The evolution of whales from land mammals.

Why is understanding natural selection important?

• To create more effective antibiotics.

• To predict future evolutionary changes.

• For studying life on Earth and potentially other planets.

• To stop the process of evolution.

What causes antibiotic resistance in bacteria?

• Bacteria's natural immunity to antibiotics.

• Overuse of antibiotics selecting for resistant strains.

• Bacteria purposefully changing to resist antibiotics.

• The development of vaccines against bacteria.
