Backbone

(Science: anatomy) The spinal column, found in vertebrate animals, which runs along the dorsal side and contains the central nerve cord (spinal cord).

The main structural feature of a polymer (chain-like) molecule from which many side chains branch off. The series of vertebrae forming the axis of the skeleton and protecting the spinal cord; the fall broke his back.A central cohesive source of support and stability; faith is his anchor; the keystone of campaign reform was the ban on soft money; he is the linchpin of this firm.Fortitude and determination; he didn't have the guts to try it.A bone structure found in vertebrates where series of vertebrae are positioned in a column with the primary function of protecting the spinal cord and maintaining structure of the organism.

Re: 5 best proofs of evolution

... others. This, I take it, is self-evident. Let me cite a common example: many animals have what we call an internal skeletal structure featuring a backbone and skull. We call these animals vertebrates. Most animals do not have these features (we call them invertebrates). The distinction between ...
