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 10
Analogous structures are a result of which type of evolution?
Describe a scenario in which divergent evolution might occur.
Describe how adaptive radiation is related to divergent evolution.
Describe how the evolution of flight in bats and birds is an example of convergent evolution.
Describe the main difference between homologous and analogous structures.
Explain how environmental pressures can lead to convergent evolution.
Describe a scenario in which divergent evolution might occur.
Describe how the evolution of flight in bats and birds is an example of convergent evolution.
Which of the following best describes homologous structures? (1) Structures with similar function but different origin, (2) Structures with similar origin but different function, (3) Structures with different origin and function, (4) Structures with similar function and origin
Which of the following best describes the process of adaptive radiation? (1) Unrelated species develop similar traits, (2) A single species evolves into many different species, (3) Two species evolve in response to each other, (4) A species becomes extinct

Which of the following is a result of divergent evolution? (1) Similar body shapes in dolphins and sharks, (2) Different limb structures in mammals, (3) Wings in bats and insects, (4) Spines in cacti and euphorbias
Fill in the blank: Structures that have a similar function but evolved independently in different species are called __________ structures.
Fill in the blank: The process by which a single species evolves into several different forms that live in different ways is called __________ radiation.
Fill in the blank: The process by which a single species splits into two or more species is called __________.
Fill in the blank: The process by which related species evolve different traits is called __________ evolution.
True or False: Adaptive radiation is a form of divergent evolution.
True or False: Analogous structures provide evidence for common ancestry.
True or False: Convergent evolution can occur in both plants and animals.
True or False: Convergent evolution can result in species that look similar but are not closely related.
