Sorry - you can't read. Pius XII ruled out an account of evolution according to which the soul emerged from matter. So does John Paull II. Pius said that purely bodily evolution on the material plane is open for discussion. John Paul says so too. There is no difference whatsoever between the actual teaching of the two Popes.
It's a good thing we live in the west where super-state church leaders need not be consulted before science can progress. It wasn't always that way, but this pope knew that faith was more than proving God's existence using a flimsy failure of imagination proof.
