they lay eggs
Probably because they evolved from reptiles and have similarities to them, such as laying eggs on land. However there are many differences too, such as birds' having feathers and warm blood.
Mammals, birds, and reptiles all derive from a single common ancestor.
No. Birds and reptiles are separate from amphibians.
There are certain birds that eat reptiles.
to stdy them differently and make charts to show differences and similarities
Reptiles are cold-blooded and birds are warm-blooded.
SIMILARITIES. Birds, reptiles, and mammals are all a part of the animal kingdom! (OH MY GOSH!) They all need the same things- food, water, vitamins, nutrients, and things of the such. They are all multi-cellular, eukaryotic organisms. They all have the ability to mate and raise/have offspring. These three also all have similar body parts, and body functions. DIFFERENCES. Mammals give birth to live offspring- birds and some reptiles don't and lay eggs. Birds have the ability of flight- mammals and most reptiles do not. Reptiles are covered in scales or some other form of rough 'coat'- birds have feathers (though some like the Cassowary have some rough and slightly scaly napes and such), and mammals have fur and things of the such. Reptiles and most birds are warm blooded- mammals are cold blooded. Hope it helped! :D ~AP Wulf
because birds and reptiles are reptiles and humans are mamals which makes use different! And birds are oviparous
Birds are most closely related to reptiles, specifically within the clade Archosauria, which also includes crocodilians. This close relationship is supported by numerous anatomical and genetic similarities, as well as shared evolutionary traits. Birds are considered a subgroup of theropod dinosaurs, highlighting their evolutionary lineage from reptiles.
Yes, birds and reptiles do lay eggs. Some reptiles, however, give birth to live young.
Birds are similar to reptiles. Both are vertebrates which lay eggs and breathe air.
N they are a seperate group like amphibians,mammals,reptiles,birds and fish
