(AP) -- WARSAW, Poland - Researchers believe they have identified the remains of Nicolaus Copernicus by comparing DNA from a skeleton they have found with that of hair retrieved from one of the 16th-century astronomer's books. Jerzy Gassowski, an academic at an archaeology school in Poland, also says facial reconstruction of the skull his team found buried in a cathedral in Poland closely resembles existing portraits of Copernicus, whose theories identified the Sun, not the Earth, as the center of the universe.
Gassowski and Marie Allen, a Swedish DNA expert, told reporters about their findings in Warsaw on Thursday. Allen said DNA from the bones and teeth matches that of hair found in a book the Polish astronomer owned. It is in a library at Sweden's Uppsala University.
