Mammals and birds are both vertebrates descended from an early reptilian ancestor.
Of course not ...no birds are mammals !!!!!!!!!!!No, they are birds.
Mammals are distantly related to birds. Oddly, if you look at an evolutionary tree, birds are actually more closely related to reptiles than they are to mammals.
No. Despite sharing some characteristics mammals and birds are not closely related.
They are not THAT closely related; bats are mammals, not birds. Both mammals and birds are vertebrate animals.
The platypus is not related to birds. They are monotremes. (mammals that lay eggs.)

While at first glance birds seem similar to mammals, they are more closely related to reptiles.
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
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.
Dinosaurs are more closely related to mammals. Both mammals and dinosaurs share a reptilian ancestor that they don't share with amphibians.
Either. A stick insect is an insect, and invertebrate and is not related to mammals or birds. Birds and mammals are more closely related to each other than they are to insects.
They are not even close. Raccoons are mammals and turkeys are birds.
