Vertebrates:
Vertebrates are all the animals with a backbone: the fishes, amphibians, reptiles, birds
and mammals. The oldest fossils of a vertebrate are small black phosphatic fragments of
bone from the Upper Cambrian of Wyoming, US. It is assumed that they belonged to a jawless
fish. The backbone provides support for the muscles that helped early vertebrates swim
through their aquatic environment in search of food. In the Silurian the first fishes with
jaws appeared. The development of jaws and teeth was very important for the vertebrates,
because it meant they could eat more different kinds of food than jawless animals. A lot
of different carnivores arose, which in turn forced their prey to improve the ability to
flee. An even more important event in the history of life occurred in the Devonian, when
some fishes moved onto land to evolve into amphibians. The amphibians in turn evolved into
reptiles in the Carboniferous, and these into mammals in the Triassic and birds in the
Jurassic.
