Again, a theory will never become a law. That is not how it works.
A theory is comprised of various laws, this is why theories are the highest level of explanations we have in science.
This is due to how science is structured and how integrity works-- no scientist will ever unironically state anything to be 100% true. They will say 99.99%, and that is to allow for future understandings of certain concepts.
However, this context is evolution-- for all intents and purposes, evolution is a LAW, if we're using the correct definition of what a law is, which is an observation:
Natural Selection is the current THEORY for evolution. Evolution is a fact; it's a natural phenomenon that has been observed. The only thing that could possibly change is the
explanation, which is natural selection (and a few other theories, I'm being brief for clarity's sake).
The problem is that natural selection is so well supported, it is incredibly unlikely that it will ever be supplanted in the future. But, we still say 99.99%, just in case.
There is a lot wrong with your understanding of this.
- You are not wrong that it is possible to supplant a scientific theory. What you don't seem to understand is that the only thing that could supplant it is ANOTHER SCIENTIFIC THEORY.
- Theories are quite literally the end result of the scientific method. You are confused-- as I stated above, the only thing that will replace a theory is another theory. Nothing else will be in its place. So, while one individual theory is not necessarily the end of that field of study, the concept of the theory IS.
- Perhaps you aren't reading what you are quoting: "
...theories are continually improved or modified... so that the accuracy of the prediction becomes greater over time". What do you think that means? Your own source is telling you that a theory will still be the best explanation we have for a phenomenon. You're quoting things you clearly do not understand.
As I just showed, no you don't.
Your original premise was that theories haven't yet become laws, but as I've shown, theories don't become laws, EVER. A law is an observation about the world. A theory explains that observation. It's impossible for the explanation to become the observation. This means your premise is faulty from the jump.
Further, you used sources that themselves state a theory is still the end goal of the scientific method. A hypothesis becomes a theory if it can be shown to be true. That's the end.
Theories are refined these days, almost never discarded, and that's because they have been tested thoroughly and to an incredible degree. The only theories these days that end up getting replaced are quantum theories, and that's because we have only just begun to scratch the surface of quantum physics.
Evolution is incredibly well understood, so much so that we can induce it in laboratory settings, and have been for thousands of years with selective breeding of dogs, cats, fish, etc. Again, evolution is not the theory; evolution is an observation. Evolution will never be supplanted in the future-- we will only ever get better at explaining it.
