Why do theories may change over time?
Theories may be changed over time as new information is discovered or new technologies are developed. New developments lead to changes in experimental methods which provide information that may or may not support the existing theory. If the theory is still supported it may be updated.
Can theories change or evolve how?
So based on that definition, theories never change into laws, no matter how much evidence out there supports them. Formulating theories, in fact, is the end goal of science.
