We tend to have this view that science is a ‘fixed’ subject, in the sense that we think of it as defined and permanent in nature. That once scientists have done their thing, that once the facts surrounding a specific topic have been gathered and a perspective has been reached, then that’s it. We’re done.

Of course, that’s not actually the case. Science evolves, it changes and is subject to refinement. That’s actually the value of the scientific process - that as more data is captured, as we see the interplay of different variables over time, we learn more.
