Fish
they are closer to mammals
Reptiles are more closely related to mammals than to fishes. Reptiles and mammals are both part of the group called amniotes, characterized by their ability to lay eggs on land. Fish, on the other hand, are a separate group with distinct evolutionary lineages from reptiles and mammals.
Reptiles
There are more mammals because of the dinosaurs.
While at first glance birds seem similar to mammals, they are more closely related to reptiles.
Neither...They were reptiles. dinosaurs were nether amphibians or mammals they were all reptiles, though they are more closely related to birds.
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.
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
Dinosaurs and mammals evolved from two separate branches of reptiles. Mammals evolved from synapisid reptiles (all of which are not extinct) while dinosaurs along with the modern branches of reptiles evolved from sauropsids. So dinosaurs are more closely related to modern reptiles than they are to mammals. In more recent years scientist tend to agree that birds are in fact a surviving branch of dinosaurs.
No, dinosaurs are more related to reptiles and birds.
Because of the shape of the teeth
Reptiles are neither mammals nor fish. Taxonomically, they are more closely related to mammals.
