What Are The Similarities Between Birds And Reptiles?

What are all the similarities and differences between birds and reptiles?

Can you please try to name the the physical similarities and differences. Can you atleast find 3 similarities and differences

Both birds and reptiles lay eggs. There are exceptions in reptiles, however; a few species of snakes and lizards may give birth to live young. Also, bird eggs have hard shells and must be turned during incubation, and reptile eggs have soft shells and turning the egg will damage or kill the embryo.

Both birds and reptiles have scales. Scales are usually noticeable on the face and legs in birds, although the feathers are actually modified scales. Birds and reptiles also have claws on their feet. Birds do not have long bony tails, while reptiles do.

What are characteristics that reptiles and birds have that mammals, amphibians, or fish do not?

In other words, a synapomorphy of reptiles and birds Both the reptiles and birds must have the same one characteristic!

Most (not all-some reptiles do have live birth) lay hard, waterproof eggs which they must then maintain the temperature of, either through burying them in the ground like most reptiles, or with their own bodies like birds.

What are the metabolic differences and effects between Arctic birds and reptiles?

Reptiles do not live in the Arctic; however, some birds do live in the Arctic even though they evolved from reptiles. Why is this and what are the metabolic differences between the two groups? What is the effect of the metabolic differences have on their relationship with the environment? Thank you to all who helps!! =)

The main difference is that birds are warm-blooded, and reptiles are cold-blooded. That means that birds can regulate their body temperature, and reptiles rely on the environment for heat. That is why reptiles can't live in the arctic, they will freeze to death, and birds, as well as all other warm-blooded animals, can live in almost any environment. Birds are thought to have evolved from reptiles, but no one knows for sure.

what is the closest living relative of the pterodactyl?

Pterodactyls are pterosaurs, and pterosaurs are reptiles, archosaurian reptiles in fact. The closest living relatives of pterosaurs are other reptiles, such as lizards, snakes, turtles and crcodilians. Among living reptiles, the crcodilians are the only surviving archosaurian reptiles, therefore the closest living relative of pterosaurs are the crocodilians. Birds are not classified as reptiles by most sane biologists around the world. Therefore, they are not as closely related to pterosaurs as the lizards are. The ancestor of birds is an archosaurian reptile, most likely Longisquama, not withstanding the largely disproven claim by many paleontologists that birds evolved from a dinosaur, which is an archosaurian reptile. Pterosaurs are closely related to the reptilian ancestor of birds, but not to birds.

How would Charles Darwin explain the relationship of Archaeopteryx to modern birds and reptiles?

How would Charles Darwin explain the relationship of Archaeopteryx to modern birds and reptiles?

Darwin would have been delighted with Archaeopteryx. He would very probably have said that it was an intermediate species between reptiles and birds because it has features found in dinosaurs, such as a long bony tail and teeth, and features found in birds, such as wings and feathers. We now know that dinosaurs were not really reptiles but Darwin didn't know that.

Archaeopteryx is almost certainly not the ancestor of modern birds, simply because most evolutionary lineages are dead ends; the chances that we just happened to find a fossil from the one lineage leading to modern birds are very slim. What it does show is that a group of species were in the process of transitioning from dinosaurs to birds at that time.
