That has nothing to do with actual Catholic theology, which doctrinally has no problem with genetics, evolution, dinosaurs, etc. This is also true of most European Protestant religious groups.
They see the bible story as allegorical and so not expected to be taken literally. Evolution is seen as simply the mechanism through which god chose to act. Creationism is largely an American thing, in Europe most Christians consider such people fringe nut jobs.
I took comparative religion studies at University. The first weeks of class, the Christian teacher (the other was a formal Buddhist) said clearly, you can easily divide modern Christian denominations between those that take the Bible as literal Truth, and those that do not; the latter generally being the literate ones.
