Reptiles and amphibians also are both vertebrate animals, meaning they have backbones. Reptiles and amphibians also both have excellent eyesight that helps them hunt prey.

What do birds and reptiles have in common?

How could we determine that the birds are closely related to reptiles?

Answer: Feather provided insulation to dinosaurs in cold weather. Later in the evolutionary process, feathers were used for flight in birds. Because dinosaurs were reptiles, it means that birds are closely related to reptiles.

How are a crocodilian and a bird related?

This means that turtles and crocodilians are the closest living relatives of birds. Birds and all other living reptiles possess one interesting circulatory similarity: Their red blood cells ( erythrocytes) contain nuclei. By contrast, humans and other mammals have non-nucleated red blood cells.

How are the circulatory systems of birds and reptiles alike?
