II. Draw the appropriate graphical representation of the
following situations.
1. A variety of species of deer lives in a certain part of the
forest. But after sometime a new organism was introduced to
the wild; the fast deer increased in number, while the slow
ones became extinct.
2. Equal population of black peppered moths and white
peppered moths inhabit a particular area in the city. After a
while, modernization and industrialization came. Because of
pollution, white peppered moths did not survive while the
dark peppered moths enjoy the smog.
3. According to Charles Darwin, the necks of giraffes vary in
length: the long neck, medium neck, and short neck.
Shortage of food and competition made the short and
medium neck giraffes disappear, while the giraffes with long
necks survived.
4. Three species of lizards inhabit a particular area in a
forest; the heavily pigmented lizard, medium pigmented, and
lightly pigmented lizard. After the introduction of new
species of birds, only the heavily pigmented lizard increased
in number; the medium and light pigmented lizard
disappeared in the forest.

developed different structures.
2. Two organisms which live in a certain area developed the
same characteristics after a while.
IV. Pattern ofEvolution.
Tell whether the diagrams illustrate convergent evolution or
divergent evolution.
