No. Mammals evolved from a group of reptiles called cynodonts. "Raptor" is an informal term for a group of dinosaurs call dromaeosaurids, which were closely related to the ancestors of birds.
A proto-mammal called the synapsid.
Birds and mammals both evolved from reptiles.
Marsupials, because Reptiles have never been mammals and have always had their offspring in eggs outside of them.

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.
It is believed that snakes evolved from lizards. Lizards are an existing group of reptiles, of course, so did not 'evolve into' anything else--they are still here. While mammals and birds evolved from reptiles, they did not evolve from lizards.
They ARE reptiles.
No. Birds evolved from a group of small carnivorous dinosaurs related to the "raptors."
Mammals did not evolve significantly during the Mesozoic period primarily due to the dominance of dinosaurs, which occupied many ecological niches and limited opportunities for mammals to diversify. Additionally, early mammals were small, nocturnal creatures that may have been outcompeted by larger reptiles for resources. The Mesozoic environment favored the reptiles' adaptations for larger size and varied diets, leading to a relatively slow evolutionary pace for mammals until the mass extinction event at the end of the Cretaceous, which allowed mammals to diversify and thrive.
The five classes of vertebrates (fish, amphibians, reptiles, birds, mammals) evolved in the following order: fish appeared first, followed by amphibians, then reptiles, birds, and finally mammals. Each class adapted and diversified to exploit different environments and ecological niches over millions of years.
no, the reptiles evolved from fish
No, although modern reptiles and dinosaurs do share common ancestors that lived in the distant past (likely the Carboniferous epoch). Birds, however, evolved from dinosaurs in the Jurassic epoch.
