In the same way, birds and mammals are technically reptiles, as they descended from the very first reptile. ... Modern birds are believed to be evolved from these bird-like dinosaurs. Their closest relatives are crocodiles and alligators.

In the view of most paleontologists today, birds are living dinosaurs. In other words, the traits that we accept as defining birds -- key skeletal features as well as behaviors including nesting and brooding -- actually arose first in some dinosaurs.

In fact, birds are a kind of fish. ... The ancestors of these early tetrapods were Sarcopterygii, what we call the “lobe-finned fishes”. Therefore, all land animals including birds and humans are the descendants of fish. According to the way that taxonomists classify animals, that makes us all fish!

The Pterosaurs and pterodactyls were once considered ancestors of birds, and there are certain similarities such as pneumatic bones, but the pterosaurs had a wing membrane like bats and no feathers. Birds evolved from a group of small bipedal dinosaurs.

Actually, birds and mammals are technically reptiles, as they descended from the very first reptile. However, when we calibrate our microscope appropriately, we find that birds are more intimately related to dinosaurs, as they branched off from a dinosaur.

Flightless birds are birds that through evolution lost the ability to fly. There are over 60 extant species, including the well known ratites (ostriches, emu, cassowaries, rheas and kiwi) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g).

Reproductive rarity. Ostriches and emus are members of the ratites, a group of flightless birds that also includes rheas and kiwis.

Yes. In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.

How did bats evolve from small pterodactyls? They didn't. Bats are mammals, just like mice, elephants, and humans. ... The structure of their arms/wings was completely different from those of bats and both were completely different from birds (who are theropod dinosaurs).

Summary: The rapid extinction of dinosaurs 65 million years ago gave rise to a stunning variety of bird species over the next few million years, according to new research. ... The researchers also showed that owls are closely related to toucans and hornbills and that falcons are closely related to parrots and songbirds.

The beginning of birds Birds evolved from a group of meat-eating dinosaurs called theropods. ... The oldest bird fossils are about 150 million years old. These ancient birds looked quite a lot like small, feathered dinosaurs and they had much in common.

Are all the theropod dinosaurs extinct? No, theropods are a monophyletic group that includes birds.

The arms are basically the limbs which are modified to wings in case of birds and bats. The wings of the bat and the bird are analogous while the forelimbs are homologous in nature. The forelimbs are modified into wings; both the bird and bats have nearly same sets of bones; which are called as homologous structures.
