Biology ⇒ Evolution and Diversity
Convergent and Divergent Evolution starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Convergent and Divergent Evolution.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe how adaptive radiation is related to divergent evolution.
Describe how divergent evolution can lead to the formation of new species.
Describe how molecular evidence can be used to distinguish between convergent and divergent evolution.
Describe how vestigial structures provide evidence for divergent evolution.
Describe one environmental factor that can lead to convergent evolution.
Explain the difference between homologous and analogous structures, providing one example of each.
Explain why similar environmental pressures can lead to convergent evolution in unrelated species.
A scientist observes that two unrelated desert plants have thick, waxy leaves. What type of evolution does this represent? (1) Divergent evolution, (2) Convergent evolution, (3) Parallel evolution, (4) Artificial selection
