Which of the following accurately describes the relationship between isolation, speciation, and biodiversity?
Which of the following accurately describes the relationship between isolation, speciation, and biodiversity?
- Speciation is a primary cause of isolation, and both processes limit overall biodiversity.
- Increased biodiversity directly prevents isolation, which in turn reduces speciation rates.
- Biodiversity directly drives isolation, which is necessary to maintain species without speciation.
- Isolation can lead to speciation, which subsequently contributes to increased biodiversity. (correct)
How does the presence of homologous structures in different species support the theory of evolution?
How does the presence of homologous structures in different species support the theory of evolution?
- They suggest a shared ancestry, indicating divergence from a common ancestor over time. (correct)
- They indicate recent adaptation to different environments, showing no ancestral relationship.
- They confirm that species were created independently with similar designs for similar functions.
- They demonstrate convergent evolution, where species independently develop similar structures.
What is the primary distinction between natural and artificial selection?
What is the primary distinction between natural and artificial selection?
- Natural selection always results in increased biodiversity, whereas artificial selection reduces it.
- Artificial selection is a more efficient process for adaptation than natural selection.
- Natural selection occurs without human intervention, while artificial selection involves human intervention. (correct)
- Natural selection primarily affects plants, and artificial selection primarily affects animals.
