Question
Read the passage and answer the following questions:
A population of birds (population A) on
a remote, isolated island is studied to determine beak length. The
resulting data are plotted in Figure 1.
Figure 1
Suppose
that 200 years later, the beaks of the birds on the island were again
measured (Population B). The data, when plotted, yielded a graph as in
Figure 2.
Figure 2
How would beak length in the bird population change after another 200-year time span?

Solution
The correct option is E It is not possible to determine how beak length might change.
Change in population is purely determined by prevailing environment. It can not be predicted how climate and hence the beak size would change after 200 year time span. Therefore, the correct answer is option E.
Change in population is purely determined by prevailing environment. It can not be predicted how climate and hence the beak size would change after 200 year time span.
Therefore, the correct answer is option E.
