Hi!
It's interesting to note that evolution is a <em>proven fact</em>. It is also interesting to note that a <em>theory </em>can be a <em>proven fact. </em>
So, with this in mind, the idea of evolution by natural selection is a <em>theory. </em>A theory cannot become a law!
It also isn't a hypothesis, as it is far beyond that. A hypothesis is just what you think will happen in an experiment.
This is a theory!
Hopefully, this helps! =)
