Leading Cardinal Redefines Church's View on Evolution - New York Times: "Mr. Ryland said the cardinal was well versed on these issues and had written the essay on his own."

The essay is encouraged (or misled), by the supporters of Intelligent Design, who claim that there is a scietific debate about theory of evolution, while there is none.

[quote] Mark Ryland, a vice president of the [Discovery I]nstitute, said in an interview that he had urged the cardinal to write the essay. Both Mr. Ryland and Cardinal Schönborn said that an essay in May in The Times about the compatibility of religion and evolutionary theory by Lawrence M. Krauss, a physicist at Case Western Reserve University in Cleveland, suggested to them that it was time to clarify the church's position on evolution.

The cardinal's essay was submitted to The Times by a Virginia public relations firm, Creative Response Concepts, which also represents the Discovery Institute. [/quote]

I would be suprised that if a biologist, even a catholic one, would change his/her view on evolution because of this, but very likely their view on Church may change.
