How are birds and reptiles related?
Birds and reptiles share a common ancestor and are both classified under the larger group called sauropsids. Modern birds evolved from a group of theropod dinosaurs, while reptiles include various groups such as snakes, lizards, turtles, and crocodilians. Both birds and reptiles lay eggs and have scales at some point in their life cycle.
Are birds reptiles or mammals?
Birds are neither reptiles nor mammals. They are a separate class of vertebrate animals called Aves. Birds share characteristics with both reptiles and mammals, but they have distinct features that set them apart, such as feathers, beaks, and laying eggs.
How are birds reptiles?
The reptile clade includes the tuatara, lizards, snakes, turtles, crocodilians, and birds. Birds are considered reptiles now to make the phylogenetic tree monophyletic. Opposite to popular belief, the reptile clade is not entirely ectothermic; ( the absorption of external heat as the main source of body heat) birds are endothermic, capable of keeping the body warm through metabolism.
Do reptiles and birds belong in a different phyla?
Yes, birds are reptiles. In fact us humans have some reptile in us, but yes, it is true the birds were previously placed in their own class, class Aves, however recent genetic evidence tells us that they are in fact reptiles. Modern birds most likely evolved from small two-legged dinosaurs called theropods. Unlike other reptiles that are ectotherms (a term more accurate than cold-blooded), birds are endotherms, meaning they use their own metabolism to maintain a constant body temperature. This may confuse many people, but cladistics has become the most widely used method in systematics as it clarifies evolutionary relationships that are not apparent in other taxonomic classifications.

Reptiles and birds are divided into two classes reptilia and aves What fossil evidence would be the BEST support for this division?
The best fossil evidence supporting the division between reptiles and birds would be transitional fossils showing a clear evolutionary pathway between the two groups. Fossils with features characteristic of both reptiles and birds, such as Archaeopteryx, provide strong support for the evolutionary link between these classes.
What characteristics are common to both birds and reptiles?
Lay eggs
What do reptiles and birds have in common?
they both lay eggs.
Distinguishing characteristics of reptiles and birds?
They're egg-laying vertebrates with close common ancestors. In cladistic classification systems birds are actually considered a subset of reptiles, as this method of animal classification goes by closest common ancestor.
Why do reptiles and birds have so much in common?
The most similar thing about birds and reptiles is that they both lay eggs. However, it is important to note that not all reptiles lay eggs. There are many species of snakes and lizards which do not lay eggs, but instead give birth to live young.

What are the simularities of reptiles and birds?
Birds are similar to reptiles. Both are vertebrates which lay eggs and breathe air.
What are the 2 major vertebrates that evolved from reptiles?
Both mammals and birds are descended from reptiles.
Which type of critter did birds and mammals evolve from?
Birds and mammals both evolved from reptiles.
Mammals and birds are descended from what group of vertebrates?
Mammals and birds are both descended from a group of vertebrates known as archosaurs. This group included early reptiles and gave rise to both dinosaurs (which birds evolved from) and the ancestors of mammals.
