Question: Does animals have the same type of back bone as humans?

Claire El Mouden answered on 19 Jun 2013:

Vertebrates (fish, birds, reptiles, mammals) all have backbones. Human are mammals so we are also vertebrates. Our backbone has undergone quite a lot of adaptations for upright walking on two feet.

There are also invertebrates (like insects) that don’t have backbones – they instead have a hard skeleton on the outside.
