11 How is natural selection in the evolution of long

necks in giraffes best explained?

A Shorter-necked giraffes were killed by long-

necked giraffes.

B Giraffe necks grew longer because of the bone

structure of the animals.

C Giraffes with longer necks survived because

they were better suited to the environment.

D Long-necked giraffes mated only with other

long-necked giraffes.

The correct option is C) Giraffes with longer necks survived because they were better suited to the environment.

Explanation:

Natural selection can be described as the phenomenon through which nature tends to favour those organisms which are better adapted to live in an environment. These organisms are able to survive and pass on their characteristics to their children.

As the Giraffes with longer necks had better adaptations to survive in the environment they were selected by natural selection for evolution. They could feed on the leaves of larger trees due to their height and passed on their characteristics to their offsprings.
