| There is not a single class of vertebrated animals which, when it first appears, is represented by analogues of the lowest known members of the same class. |
| In the vertebrated animals the nervous system is also more developed. |
| There were four short, stout swimming paddles, and the tail was vertebrated. |
| This type of fin is, therefore, vertebrated, the other non-vertebrated. |
| The Archopteryx tail is vertebrated, the typical birds non-vertebrated. |
| Why should not all invertebrated animals have risen into vertebrated? |
