Question

What adaptations of reptiles made successful colonization of land possible

Answer 1

• There are three main adaptations of reptiles that enabled them to live on land.

1. The presence of lungs enabled them to venture away from water since they did not need water for gaseous exchange.
2. The presence of a dry cornified skin with epidermal scales enabled them to reduce water loss through the skin.
3. The presence of metanephric kidneys enabled them to excrete uric acid while reducing water loss at the same time.
