Reaching back through time to see the dead, or perhaps not?

Scientists in Warsaw, Poland claim to have identified the remains found in a grave to be those of Nicolaus Copernicus, the famous 16th century astronomer and scientist.  DNA comparison between some hairs in an archive and the skull are the proof. 

WARSAW, Poland – Researchers said Thursday they have identified the remains of Nicolaus Copernicus by comparing DNA from a skeleton and hair retrieved from one of the 16th-century astronomer's books. The findings could put an end to centuries of speculation about the exact resting spot of Copernicus, a priest and astronomer whose theories identified the Sun, not the Earth, as the center of the universe.

Polish archaeologist Jerzy Gassowski told a news conference that forensic facial reconstruction of the skull, missing the lower jaw, his team found in 2005 buried in a Roman Catholic Cathedral in Frombork, Poland, bears striking resemblance to existing portraits of Copernicus.

This is all very interesting and I'm sure they worked very hard on this, but the skeptic in me disagrees.  So after careful consideration and a 30-second search through IMDb, it's plain to me that they've not found Copernicus, but rather James Cromwell, noted character film and television actor.  What do you think?
