The answer to this is : B, Their roots.
Answer:
Option (A).
Explanation:
Evolution may be defined as the change in the characteristics of a species over several generation with time. Natural selection acts as a main drivinf force for the evolution.
The drought of 1977 is responsible for the species evolution. The species is larger in this case (as mentioned in the question) and the species has deeper beaks over time. The birds have relatively large and deep beaks because they can easily crack the food.
Thus, the correct answer is option (A).
Random distribution is not the same predictable spacing. Hence, the correct answer would be False
In actual fact, random distribution can be said to be the direct opposite of predictable spacing.
For example, when a group of numbers is randomly distributed, each number has an equal chance of being located within the distribution. In predictable spacing, each number would have a predefined probability or an unequal chance of being located.
