Question

The species which were not able to adapt to their environments through genetic changes to their skeletons were not able to survive. The given statement is an example of

• A. Skeletal Adaptations
• B. Coloration
• C. Physiological adaptations
• D. All of the above

Answer 1

The correct option is A Skeletal Adaptations

The given adaptation in lizard is an example of skeletal adaptation of natural selection. According to this adaptation, the individual who didn't develop the skeletal changes died. This type of adaptation can be seen in some species (lizards, giraffes) of animals who adapted themselves to the environment through genetic changes in their skeletons. For example, development of long neck in giraffes to reach food sources of the upper part of the trees. It is said that those died who didn't develop the long neck. Another example is development of longer leg bones in lizards to help them to climb up during periods of flood and to escape predators in the ground. Those lizards who didn't develop long leg bones, died. So, the correct option is A.
