Ch 36 in 'Humanae Generis' - got as far as saying ..."the Teaching Authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter "...

Of course the 'present state' in both science and theology and Scripture had developed considerably since the 1950's!

Recent Popes, such as John Paul 2, and Benedict, -- not sure if Pope Francis has said anything on this as yet –  have told us that Catholics can believe in Evolution.
