Although every detail of its processes could not be explained and there are disagreements on these details, the theory of evolution is unlikely to be overturned. The only objections to evolution are theological. Even if the evolution theory is indeed overturned, creationism will not become the default explanation for the origin of species. It must exhibit evidential merits.
For natural evidence, one may like to read “Why Evolution is True” by Professor Jerry A Coyne.
