A pоpulаtiоn оf ground finches on the Gаlápаgos Islands primarily feeds on small seeds. During an unusually long drought, only plants producing large, hard seeds survived. Over several generations, researchers observed that the average beak size of the finches increased. 1. Which evolutionary mechanism best explains the observed increase in average beak size among the finch population? [color1] 2. What was the main selective pressure that influenced the evolution of beak size in this population? [color2] 3. Suppose that after the drought, researchers found that some finches with smaller beaks still survived by eating insects instead of seeds. What evolutionary concept does this illustrate? [color3] 4. If the drought continued for many more generations, and nearly all finches ended up with very large beaks, which type of natural selection would this demonstrate? [color4] 5. Which of the following statements best reflects why variation in beak size was important for the survival of the finch population during the drought? [color5]
