Convergent and Divergent Evolution
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 9
Describe how divergent evolution can lead to the formation of new species.
Describe how environmental pressures can lead to convergent evolution.
Describe one example of convergent evolution in plants.
Describe the difference between convergent and divergent evolution.
Describe the role of adaptive radiation in divergent evolution.
Explain how the forelimbs of whales and bats are an example of divergent evolution.
Explain the difference between homologous and analogous structures.
Explain why marsupial mammals in Australia and placental mammals elsewhere can look similar despite being unrelated.
Homologous structures are evidence of which type of evolution? (1) Convergent, (2) Divergent, (3) Parallel, (4) None of these
Which of the following best describes analogous structures? (1) Same structure, different function, (2) Different structure, same function, (3) Same structure, same function, (4) Different structure, different function
Which of the following best describes divergent evolution? (1) Different species developing similar traits, (2) One species evolving into two or more different species, (3) Unrelated species merging into one, (4) Species remaining unchanged over time
Which of the following is a characteristic of convergent evolution? (1) Evolution of similar traits in unrelated species, (2) Evolution of different traits in related species, (3) No change in traits, (4) Loss of traits in a population
Fill in the blank: Structures that have a common evolutionary origin but may have different functions are called __________ structures.
Fill in the blank: Structures that have similar functions but different evolutionary origins are called __________ structures.
Fill in the blank: The process by which a single species evolves into several different forms is called __________ evolution.
Fill in the blank: The process by which related species become more different over time is called __________ evolution.
True or False: Analogous structures provide evidence for common ancestry.
True or False: Convergent evolution can result in similar adaptations in organisms that are not closely related.
True or False: Divergent evolution can occur when populations of the same species become geographically isolated.
True or False: Divergent evolution results in species becoming more similar over time.
