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 11
Describe a scenario in which divergent evolution might occur.
Describe how convergent evolution can complicate the classification of organisms.
Describe how divergent evolution can lead to the formation of new species.
Describe the main difference between convergent and divergent evolution.
Explain how environmental pressures can lead to convergent evolution.
Explain the difference between homologous and analogous structures.
Explain why homologous structures are important evidence for divergent evolution.
