I do not understand the structure and the meaning of the following underlined part. Is something omitted?
Many people think that if scientists find evidence that supports a hypothesis, the hypothesis is upgraded to a theory and if the theory if found to be correct, it is upgraded to a law. That is not how it works at all, though. In fact, facts, theories and laws - as well as hypotheses - are separate parts of the scientific method. Though they may evolve, they aren't upgraded to something else.
Thank you.
