Dinosaurs evolved from more primitive reptiles, very much like lizards. The evolutionary step that made them so successful was putting their legs directly underneath their bodies so they could stand upright with the stability of bones rather that with the strength of muscles. This allowed them to put on more weight than would have been possible for a land-dwelling animal with limbs at its sides, as with the lizards and frogs.

Did apes evolve from dinosaurs?
No, apes did not evolve from dinosaurs. Apes belong to a different evolutionary line known as the hominids, which diverged from the lineage of dinosaurs millions of years ago. Dinosaurs became extinct around 65 million years ago, while apes evolved later, branching off from a shared ancestor with monkeys around 25 million years ago.
Is it possible the asteroid that destroyed the dinosaurs has any connection with the existence of humans?
An asteroid did NOT destroy the dinosaurs. A flood did. Read the Bible. :) The flood was the one who killed the dinosaurs, but Noah took small dinosaurs (e.g lizards, crocodiles).
What was the positive result of the dinosaur extinction?
The extinction of the dinosaurs is one of the many events that allowed humans to evolve. After the dinosaurs died out, mammals began to occupy the world they left behind. Mammals grew and diversified, spreading throughout the Earth, and eventually giving rise to humans.
What will probably be without the dinosaurs extinct?
For one thing, humans wouldn't exist. If the dinosaurs had survived, the small mammals that would have eventually evolved into humans wouldn't have had the chance. Most large mammals - lions, elephants, moose, kangaroos, etc. - wouldn't have had the chance to evolve either. All the big, widespread species would be reptiles or birds.
Is the dinosaurs ALL wiped out when the large meteorite hit the earth?
According to modern scientific theory, all the remaining dinosaurs went extinct during or shortly after the asteroid hit the Earth 65 million years ago.No evidence of a large meteorite hitting the Earth.
Did dinosaurs evolve into reptiles?
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
From what dinosaur did cats evolve?
Cats did not evolve from dinosaurs. Cats evolved from a common ancestor of modern carnivores, which lived after the extinction of dinosaurs.
Did birds evolve from lizards?
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)
When did the piranha first evolve?
in the dinosaurs epoch
When did dinosaurs evolve?
Dinosaurs evolved 225 million years ago in the Late Triassic.
Did any dinosaurs live in the Cambrian Era?
No. In the Bambrian Era, dinosaurs had yet to evolve.
Why did the dinosaurs evolved?
They didn't evolve! They went extinct.
Did primates evolve before dinosaurs became extinct?
no
Where elephants here before dinosaurs?
Mammals did not evolve until dinosaurs were prolific when they did appear they were very small and very scarce when dinosaurs died out.
Did birds ever evolve to dinosaurs?
No. It's the other way around. A branch of the dinosaurs evolved into birds.
Did horses develop during the last days of the dinosaurs?
No, horses did not evolve alongside dinosaurs. The earliest horses evolved shortly after the extinction of non-avian dinosaurs.
Did underwater dinosaurs evolve into crocodiles?
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.
