Pope Pius XII said so in Humanae Generis in 1950.
The Church rejects a polygenistic belief - i.e. that mankind is descended form multiple "first parents." HG states that the entire human race is descended from one set of people - the two people we call Adam and Eve.
Here is the relevant part:
"When, however, there is question of another conjectural opinion, namely polygenism, the children of the Church by no means enjoy such liberty. For the faithful cannot embrace that opinion which maintains that either after Adam there existed on this earth true men who did not take their origin through natural generation from him as from the first parent of all, or that Adam represents a certain number of first parents. Now it is no no way apparent how such an opinion can be reconciled with that which the sources of revealed truth and the documents of the Teaching Authority of the Church propose with regard to original sin, which proceeds from a sin actually committed by an individual Adam and which, through generation, is passed on to all and is in everyone as his own."
Did you know you are obligated to believe in a literal Adam/Eve? Indeed, and I don't know what that does to your freedom to believe in evolution (of humans, at least).
