Answer 2

The animal kingdoms like reptiles, amphibians, and birds are the three organisms that have a backbone and scales, lay eggs, and walk on land.

• Amphibians: The amphibians have evolved from their ancestor known as the aquatic tetrapods. These tetrapods have appeared during the Devonian period to the Pennsylvanian Subperiod.

• Reptiles: They have evolved from amphibians and therefore, their common ancestor is similar to that of amphibians. Examples are turtles, crocodiles, snakes, and lizards come into this category.

• Birds: They have evolved from theropod dinosaurs that had long wings that resembled that of the present-day birds. Though they have arrived from dinosaurs, they show similarities even with mammals in terms of 4 chambered hearts and are warm-blooded.
