No kidding. And who cares. The Vatican is mistaken about a great many things. Binding and loosing is one. Galileo is another. One can make a laundry list that begs why anyone should lend an ear to the Vatican as they're wrong on so much. It begs the question. Who cares.
It only proves that accepting evolution and being a Christian aren't incompatible, as some creationists pretend that they are.
At the very least, the Vatican is an authority on one thing - how to be a Catholic. And except for the nutjobs who think that Catholics aren't Christians, that alone is enough to disprove the contention.
