Bats ARE mammals.
All bats are mammals. There are more than 1,000 known species of bat, too many to list here.
Bats are in their own family of mammals. As mammals they are more closely related to cats and dogs than they are to birds.
Humans are more closely related to bats than to chickens. Both humans and bats are mammals, sharing a more recent common ancestor, while chickens are birds, which diverged from mammals much earlier in evolutionary history. This genetic and evolutionary proximity means that humans and bats have more similarities at the molecular and anatomical levels compared to humans and chickens.
The only mammals that can fly are the bats, but there are many more than 20 kinds of bats.
No. Generally speaking mammals are more intelligent than non-mammals
No. Bats are flying mammals. Flying squirrels glide rather than fly. I know of no others.
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
well birds get eating more than mammals so they help care more.
yes
A platypus gives milk but lays eggs. Bats are capable of flight (rather than gliding).
Dinosaurs are more closely related to mammals. Both mammals and dinosaurs share a reptilian ancestor that they don't share with amphibians.
No. Birds and mammals have radically different lung designs. Birds have a far more complex, but more efficient design than mammals do.
