Carlesi and Gavazzeni commented that if McCartney really wanted to put an end to these rumors, he could have offered to take a DNA test with his father or his younger brother, Mike, but he didn't. McCartney took a DNA test only once, but the authors of the article point out that the DNA test created more confusion and suspicion of his true identity, not less.
In 1962, when the Beatles were living in Hamburg, Germany and still unknown to most people, Paul McCartney had a brief affair with a German woman named Erika Wohlers. She gave birth to a daughter, Bettina, in December 1962, which was during the time the Beatles were starting to become famous. The Beatles soon left Germany, and McCartney abandoned Erica. Around 1967 McCartney agreed to pay 30,000 deutsche marks to support Bettina, but he was not admitting to being her father, even though she claims her German birth certificate identifies him as her father!
Once Bettina became an adult, she asked a German court to have McCartney recognize her as his natural daughter. McCartney had to submit to a DNA test, and the test showed that he was not her father. Interestingly, based on an autograph signed by McCartney, together with some photos taken for the occasion, Bettina accused the person who took that DNA test of being a substitute for Paul, not the real Paul McCartney! The autograph, for instance, was signed by somebody right-handed (Paul was left-handed). More information about this DNA test is here.
