Beaks of Finches Lab Review

Base your answer(s) to question(s) on the diagram below and on your knowledge of biology. The diagram shows the heads of four different species of Galapagos Islands finches. The four different types of beaks shown are most likely the result of

• gene manipulation 

• natural selection 

• unchanging environmental conditions 

• patterns of behavior learned from parents

What did the beak type of finches on different islands tell Darwin?

• Finch populations evolved over time to favor beaks based on food type

• Finch populations had not evolved over time

• The finch beaks had no relationship to the available food on the islands

• Humans artificially selected finches based on their desired beak type

Which of the following best explains the concept of "survival of the fittest" in the context of finch beak evolution?

• Finches with the most attractive beaks are more likely to find a mate

• Finches that can sing the loudest will scare away predators and survive

• Finches with beak shapes that best match available food sources are more likely to survive and reproduce

• The largest finches are always the ones that survive, regardless of beak shape

Which of the following statements is true regarding the evolution of finch beaks?

• Finch beaks have evolved primarily due to the finches' conscious efforts to change

• Finch beaks have evolved in a random direction, with no relation to the environment

• Finch beaks have evolved through natural selection, adapting to the demands of their environment

• Finch beaks have not evolved; they have remained the same since the finches first appeared

Which of the following scenarios would most likely lead to a rapid evolution of finch beak shapes?

• A stable environment with no changes in food sources

• A sudden change in the environment that alters the types of available food

• An increase in the number of finch predators

• A decrease in the finch population due to disease

What is the significance of variability in finch beak sizes within a single species?

• It indicates that the finches are preparing to evolve into a new species

• It suggests that there is no competition for food within the species

• It demonstrates genetic diversity, which can be advantageous in adapting to changing environments

• It shows that the finches are not true species

How does the beak shape of finches support the theory of evolution?

• It shows that finches can change their beak shape at will

• It demonstrates that beak shapes have remained the same over millions of years

• It provides evidence of adaptation and natural selection based on environmental needs

• It indicates that all finches will eventually evolve to have the same beak shape
