Evolution Quiz

What is natural selection?

• Natural selection is the process by which traits or characteristics are randomly determined in a population.

• Natural selection is the process by which certain traits or characteristics become more or less common in a population over time, based on their ability to survive and reproduce in a given environment.

• Natural selection is the process by which humans choose which traits or characteristics they want in a population.

• Natural selection is the process by which traits or characteristics are passed down from one generation to the next without any changes.

Give an example of natural selection in action.

• Evolution of pesticide resistance in insects

• Evolution of antibiotic resistance in bacteria

• Adaptation of plants to survive in extreme climates

• Development of immunity to diseases in humans

What is adaptation?

• The process of ignoring new conditions or changes in the environment.

• The process of staying the same despite new conditions or changes in the environment.

• The process of avoiding new conditions or changes in the environment.

• The process of adjusting to new conditions or changes in the environment.

How do organisms adapt to their environment?

• Through random mutations

• By changing their DNA

• Through conscious decision-making

• Through natural selection

What is genetic drift?

• Genetic drift is the intentional manipulation of genes in a population.

• Genetic drift is the result of natural selection favoring certain alleles over others.

• Genetic drift is the process of genetic material being passed down from parent to offspring.

• Genetic drift is the random change in the frequency of alleles in a population over generations.

Explain the concept of genetic drift with an example.

• Genetic drift is the result of natural selection.

• The founder effect is caused by deliberate human intervention.

• Genetic drift occurs only in large populations.

• Genetic drift is a random fluctuation in the frequency of alleles in a population. An example is the founder effect, where a small group of individuals from a larger population establish a new population with a different allele frequency due to chance.

What is speciation?

• The process by which species reproduce asexually.

• The process by which new species arise from existing species over time.

• The process by which species become extinct.

• The process by which species evolve into different genera.

How does speciation occur?

• Speciation occurs when a population of organisms interbreeds with another species and creates a hybrid species.

• Speciation occurs when a population of organisms becomes isolated from the rest of its species and evolves independently, developing genetic and physical differences that eventually lead to the formation of a new species.

• Speciation occurs when a population of organisms randomly mutates and evolves into a new species.

• Speciation occurs when a population of organisms intentionally adapts to a new environment and becomes a new species.

What is comparative anatomy?

• The study of the anatomy of plants.

• The study of the anatomy of extinct species.

• The study of the anatomy of only one species.

• The study of similarities and differences in the anatomy of different species.

How does comparative anatomy provide evidence for evolution?

• Comparative anatomy only provides evidence for minor changes within a species, not for evolution.

• Comparative anatomy studies the similarities and differences in anatomical structures to provide evidence for creationism.

• Comparative anatomy is not a reliable source of evidence for evolution.

• Comparative anatomy studies the similarities and differences in anatomical structures to provide evidence for evolution.
