All mammals have a spine or a backbone. Another word for a backbone is a "vertebra" and thus all mammals are "vertebrates".
However the presence of a backbone does not DEFINE a mammal because other animals also have backbones, eg reptiles, birds and fish - these animals are also "vertebrates".
Mammals are mammals because they are the onlyanimals to have fur/hair and feed their young on milk (there are some exceptions of non-mammals with fur and who feed milk to their young, not not many).
The reason for all these animals being "vertebrates" is because a long time ago in geological history they all evolved from an animal that had a backbone.
The defining characteristic of a mammal is that it feeds its young on mothers' milk. This is the case whether the mammals is a placental, a marsupial or a monotreme (egg-laying mammal).
Mammals have a more complex nervous system over other vertibrits and a larger brain size in comparison to body ratio than other vertibrits. Mammals birth thier young alive and produce milk for them.
All mammals are vertebrates (meaning they all have a backbone).
Birds are vertebrates as they have a spine and an internal skeleton.
