What is the significance of paleontolagical evidence?
The discovery of fossils showing forms of animals that had never previously been seen began to cast serious doubt upon creationist theories.
    Fossils provide the only direct evidence of the history of evolution.
 The strata of rock in which fossils are found give us clues about their relative ages. Similarly, new technological techniques such as radioactive carbon dating help determine the absolute ages of fossils. In addetion to supplying a fossil's relative age, rock strata can also give clues about the environments in which an animal or plant lived. The chemical make-up of these strata can tell us the balance of gases in ancient atmospheres. Major cataclysmic events such as eruptions and meteor strikes also leave there mark on the fossil record.
