1/25 men might raise another man's child
One in 25 fathers could unknowingly be raising another man's child, British scientists said Thursday. Researchers at Liverpool's John Moores University examined the findings of dozens of studies, published over the past 54 years, on cases of paternal discrepancy, where a man is proved not to be the biological father of his child. The studies, most of them peer reviewed, came from countries as varied as the United States, Finland, New Zealand, South Africa and Mexico. The findings of the studies varied dramatically — some concluded that only one man in 100 is not the father of his child while others put the figure as high as 30 percent. The Liverpool researchers calculated the median figure at around 4 percent, suggesting that as many as one in 25 men worldwide is not the biological father of a child he believes to be his. "The importance lies not so much in the figure itself but in the implications, given that as a society we are increasingly making our decisions on the basis of genetics," said one of the researchers, Professor Mark Bellis. "If someone knows that their father had a history of hereditary heart
disease, they might be tempted to alter their own diet," he said. "Obviously
they need to be making that decision on the basis of accurate information about
who their father really is."
