Unit 4 Review: Galapagos Finches

How did the variation in beak shapes among the finches relate to their survival on different islands?

• Beak shapes were irrelevant to their survival.

• Finches with diverse beak shapes could exploit different food sources.

• All finches had the same beak shape, which did not affect survival.

• Finches with larger beaks were always more successful.

What was the effect of natural selection on the finches' ability to survive during a drought?

• Only finches with bright feathers survived.

• Finches with beaks suitable for available food sources were more likely to survive.

• Finches with smaller beaks perished due to lack of food.

• Natural selection had no impact during the drought.

What effect did Darwin's insights about the finches have on the broader understanding of evolution and biological diversity?

• They supported the idea that species are fixed and unchanging.

• They highlighted the importance of genetic engineering in evolution.

• They illustrated how environmental pressures can lead to species adaptation over time.

• They led to the belief that all species originated from a single island.

Compare the beak shapes of finches that feed on insects with those that eat seeds. How do their beak structures reflect their food sources?

• Insect-eating finches have long, slender beaks; seed-eating finches have strong, thick beaks.

• Both types of finches have identical beak shapes.

• Seed-eating finches have curved beaks, while insect-eating finches have flat beaks.

• Insect-eating finches have thick beaks; seed-eating finches have pointed beaks.

Contrast Darwin's observations of the finches with the prevailing belief at the time about species. What were the key differences in these perspectives?

• Darwin believed in fixed species, while others saw species as adaptable.

• Darwin observed adaptability and variation, challenging the idea of fixed species.

• Other scientists believed in evolution, while Darwin did not.

• Darwin's observations aligned perfectly with the ideas of his contemporaries.
