Scientist think that birds are related to dinosaurs because as you study the fossilised bones of certain therapod dinosaurs especially dromaeosaurs you start to notice many similarities between them and modern day birds.
The famous archeopteryx for example, which is historically considered the first bird, looked very much like a bird but still had claws on its wings and had a mouth full of teeth. Other dinosaurs from the same time period look even more like birds.
In fact experiments done on modern day bird embryos show that if you play around with the genes of birds you can engineer dinosaur features such as teeth, long dinosaur tails etc.
All the key features that people associate with birds developed when they were still dinosaurs. Dinosaurs had feathers, dinosaurs had oval shaped eggs, dinosaurs had beaks.
The morphology of birds is so similar to some dinosaurs that scientist are starting to consider birds as not just related to dinosaurs but actually as avian dinosaurs.

∙ 13y agothey lay eggs like reptiles and the bone structure is very similar to some dinosaurs 93,000,000 years ago. scientists believe some dinosaurs had feathers too, so its not really that hard to see
Wiki User
∙ 15y agoRaptors or beast-footed dinosaurs had claws similar to the claws of birds. Both birds and reptiles have scales. Transitional species like archaeopteryx had feathers.

What animal do scientists think penguins evolved from?
Penguins evolved from birds. :)
Are reptiles evil or not evil?
Reptiles are not evil, the instinct for them is to fend for them selves and if that means to kill, then let it be...this is like asking if humans are evil...we have that choice and usually it is to fend for our selves (TheAdventMaster:I disagree. I think reptiles are definitely evil. They are the descendants of dinosaurs, after all. Birds are, too.In my opinion, if you're pro-reptile, you're anti-human.)
What animals belong in the bird group?
Chickens belong to the bird group because they are land animals and they lay eggs.Chickens are classified as follows:Kingdom: AnimaliaPhylum: ChordataClass: AvesOrder: GalliformesFamily: PhasianidaeGenus: GallusSpecies: Gallus gallus
Why scientists think osprey and penguin belong to the same group?
Because they are both birds and the have feathers and eat fish. i think.... hope i helped! :D
What eats a hornet?
Other hornets, spiders, birds, snakes and some other reptiles and amphibians. Some mammals also eat hornet grubs, such as bears for example.
Are dinosaurs closer to amphibians than to reptiles?
They are generally considered reptiles, though some think they should have their own class.
What dinosaur is a reptile?
Yes, Dinosaurs were reptiles. Did you know Dinosaurs closest living relatives may be birds?EDIT: Birds ARE dinosaurs and therefore Birds are also reptiles!When most people think of reptiles they think of cold blooded, scaly, sprawling lizards and crocodiles. Birds on the other hand are the only type of warm blooded, fuzzy reptiles alive today.Crocodilians are dinosaurs and birds closest living relatives.
Do scientists think dinosaurs are amphibians or reptiles?
no, they are considered to be an actual type of reptile.
Why do scientists think that dinosasurs evolved into birds?
90% of modern birds
Is a bird a mammal it's not a amphibian insect or reptile?
Birds are... birds. I think there are 4 categories. Mammals, Amphibians, Reptiles, Birds.
Does Gila monsters eat fruits?
I don't think so. I think they eat eggs, reptiles, birds, and carcasses
What animal do scientists think penguins evolved from?
Penguins evolved from birds. :)
Is a jackal Carnivore or Omnivore?
carnivore, they eat small mammals, birds and reptiles.
What group is a duck between fish ormammals or birds or reptiles or anphibins.?
i think it must be a bird
Why do we think birds Evolved from crocodiles and alligators?
They didn't but they do share a common ancestor. Looking at fossils, scientists have determined that bird evolved from small carnivorous dinosaurs. Both dinosaurs and crocodiles stem from a group of reptiles called archosaurs.
Why do scientists think that some dinosaurs are like today's birds?
becuase of simalarities
Evidence indicates that birds are decended from where?
Like reptiles,birds have internal fertilization and lay eggs. So I think it is reptiles.Yeah try reptiles.GOOD LUCK!
