After thousands of experiments and observations that support the theory of evolution, for example, it is now accepted as being .

Scientists who find new evidence that supports or undermines a theory should publish their results in a respected scientific . The evidence will only be accepted as valid if other scientists can the observation or experiment and get the same results.
