If I recall correctly at the turn of the century (1900 AD) a physicist thought that with Newton et al, that all that was left in physics was to dot the I's and cross the t's, yet all the big tenets of Classical physics were shown to be in error by Quantum Mechanics. Not refined by, but wrong. Although it is still true that Newton's physics are just fine for building a skyscraper, for example. But in search for ultimate truth, they are not, strictly speaking, true. They are merely sufficient.There is a thing in the philosophy of science called "the problem of history' which briefly stated is that the problem with scientific theories (and what people think is 'proven') is that every theory we've had so far has been shown to be wrong by later theories. So, what does that imply for today's theories?
I leave it to you, humble reader
No, that's not the case at all. Many theories, particularly from the days before empirical testing was the norm, have been thrown out, like the four elements theory or phlogiston theory. But once we started testing things and looked for independently verified, repeatable testing as the basis for scientific knowledge, the majority of theories we've arrived at have only been updated and tweaked. Newton's calculations for the effects of gravity were magnificent and groundbreaking, and when Einstein came along and put forward his own model for gravity, all he did was improve upon Newton's work. The old theory wasn't "wrong", it was incomplete. Modern science is improving our understanding of nature by refining the theories that work, not replacing them outright.
Also, anyone who uses the argument that "evolution is only a theory" (the other guy above, not you Raoul), doesn't know what a theory is within science, and doesn't understand evolution by natural selection.
Evolution, now that's really out of my line, but Iast I heard, humans shared a common ancestor with apes, we are not apes. The evolutionary lines split quite some time ago.
