Patterns of Evolution
Biology ⇒ Evolution and Diversity
Patterns of Evolution starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Patterns of 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
Describe a scenario in which coevolution might occur between two species.
Describe how environmental pressures can lead to convergent evolution.
Describe one example of convergent evolution in animals.
Describe the main difference between convergent and divergent evolution.
Explain how adaptive radiation can increase biodiversity.
Explain how divergent evolution can lead to speciation.
Explain the difference between homologous and analogous structures.
Explain why analogous structures are not evidence of common ancestry.
Which of the following best describes convergent evolution?
(1) Two unrelated species evolve similar traits due to similar environments
(2) Two related species evolve different traits due to different environments
(3) A single species splits into two due to a physical barrier
(4) A species remains unchanged over time
Which of the following best describes the relationship between predator and prey in coevolution?
(1) Only the predator evolves
(2) Only the prey evolves
(3) Both evolve in response to each other
(4) Neither evolves
Which of the following best illustrates divergent evolution?
(1) The development of similar eyes in octopus and humans
(2) The finches on the Galápagos Islands evolving different beak shapes
(3) The evolution of antibiotic resistance in bacteria
(4) The relationship between bees and flowers
Which of the following is a key feature of adaptive radiation?
(1) Slow evolution of a single species
(2) Rapid evolution of many species from a common ancestor
(3) Evolution of similar traits in unrelated species
(4) Evolution in response to another species
Fill in the blank: The evolution of cacti in the Americas and euphorbias in Africa, both with thick stems and spines, is an example of __________ evolution.
Fill in the blank: The evolution of similar traits in related species that are geographically separated is called __________ evolution.
Fill in the blank: The evolution of similar traits in unrelated species due to similar environmental pressures is called __________ evolution.
Fill in the blank: The process by which a single species evolves into several different forms that live in different ways is called __________.
True or False: Adaptive radiation can occur on islands after a few individuals colonize them.
True or False: Adaptive radiation can result in the rapid formation of many new species from a single ancestor.
True or False: Adaptive radiation often occurs when organisms colonize new environments with few competitors.
True or False: Allopatric speciation is a type of divergent evolution.
