Some specific solutions (esp. in rapidly reproducing organisms like bacteria) can evolve over a much shorter time. The end result of a chain of changes might take a long time (esp. in complex, slowly changing species) but specific changes can be quicker. Also changes don't have to increase survival chances in order to be maintained. You get changes over different parts of the population over a long time, then then the environment changes and some of the mutations turn out to be an advantage, perhaps only the members of a species with that change survive. So there can be a sudden change in the overall species while the individual genetic changes happen over time.

Scientists understand that there are things about evolution that are not yet understood, which they accept as challenges. Non-scientists look for excuses not to believe in evolution, so anything that can't be explained is "proof" that the entire theory is wrong. I am not aware of any other body of knowledge that is rejected, in its entirety, because some parts are not yet understood. The alternative to evolution is some form of magic. I bet you can't explain magic, either.
