Evolution is generally a gradual process, such that it is generally difficult to classify transition species one way or the other. Would you say birds are reptiles? Birds are dinosaurs. Dinosaurs and reptiles share a common ancestor, probably dating to some time in the early Triassic. That would be around 250 million years ago.
No modern reptiles are descended from dinosaurs. The only living descendants of dinosaurs are birds.
About 65.5 million years ago. Note however that Birds are the descendants of dinosaurs, so they are not actually extinct.
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
No. Mammals evolved from synapsid reptiles, a group not closely related to dinosaurs. Dinosaurs are more closely related to modern reptiles and birds than they are to mammals.
what an interesting topic! Birds and reptiles are the living descendantsof the dinosaurs that survived the meteorite-triggered mass extinction that killed off most of the species living 66 million years ago. And of all reptiles, crocodiles are the most closely related to birds.
No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)
But they did. Specifically, birds evolved from a subgroup of dinosaurs (which were reptiles) known as theropods. There is a lot of fossil and anatomical evidence for this.
No, modern reptiles did not evolve from dinosaurs. Modern reptiles and dinosaurs both belong to the group known as archosaurs, but they evolved along separate lineages. Dinosaurs went extinct around 65 million years ago, while modern reptiles, such as snakes, lizards, and turtles, continued to evolve and diversify.
Because they can generate their own body heat - reptiles cannot and need a warm environment
Dinosaurs evolved from reptiles not the other way around. The first reptiles where thought to have evolved during the late Carboniferous Period about 320 to 310 million years ago. Dinosaurs do not appear in the fossil record until the late Jurassic Period about 230 million years ago. They evolved from the reptilian infra class Archosaurs.
What do you mean? Dinosaurs ARE ancient reptiles.
because reptiles have lived all theese years (since the dinosaurs) without having to change and are getting away with it they do not have the need to evolve that is why they dont
Dinosaurs are reptiles.
yes dinosaurs are a kind of reptiles they are big lizards
