Actually, dinosaurs are bird-like animals, with a similar anatomy and lifestyle. They used to be classified as reptiles, or lizards, but now we have all the evidence in the world to say that "no, dinosaurs are more birdlike". Yet, this is still a widely debated subject.
Early land animals had to return to the water to reproduce.
No. It is classified as a fish.No... Its a fish.
Animals, all life, evolved from what was already there. The reason all things look the same is that they share ancestry.
There are three main groups of reptiles. One group is the lizards and snakes. Although snakes do not have legs, they evolved from lizards, which have legs. The second group is the turtles and tortoises, which have a heavy shell that is attached to the skeleton. The third group is the crocodiles and alligators (the crocodilians). The last two groups are generally found in or near the water.
I think you are looking for reptiles.
endosymbiosis.
Some animals are mammals and reptiles i think......
all scientist believe animals can think because if an animal could not think it would not move or do anything. they need to think 'move' to move etc.
i think sea iguanas
most people think there reptiles
vertebrates and invertebrates
They do not think plant life 'came' to Earth. They believe it evolved here.
Zoologists who studies reptiles and amphibians are called Herpetologists
In most ways yes. Some animals have evolved from these amazing creatures and some are still here such as the crocodile. But the animals that people think of when they hear dinosaur are extinct. Giant Reptiles such as the Tyrannosaurus Rex and the Stegosaurus are gone. But still thanks to the crocodile some of the history is still alive.
Animals with scales are reptiles and fish. They are cold-blooded and lay eggs. Reptiles generally have different, tougher scales than fish, allowing them to live on land without drying out so easily. Birds also can have scale-like things on their legs. Feathers probably evolved from scales. It is thought that Dinosaurs had scales but some people think some may have developed feathers.
The first dinosaur's appeared on earth at about 230 million years ago. the first dinosaur was called Eoraptorc, found in Argentina and Brazil. It was a small meat eating creature. Scientist think there may be older dinosaurs out there.
