All Vertebrates are alike in that they all have Backbones.BTW: That's what the name means ...They are a sub-phylum (vertebrata) of chordates that have spinal columns.
Humans are mammals. They are warm-blooded vertebrates, they have a body covering of hair or fur, they suckle their young with milk and they have specialized teeth.
