Dramatic revelations about parentage might be staples of salacious soap operas and reality TV shows, but new research has suggested that unknowingly bringing up a child who isn’t yours is much more common than you might think.

1 in 50 British fathers may be unwittingly raising a child which isn’t their biological offspring, the study suggests.

Researchers at Leuven University in Belgium said that they decided to conduct the first ever in-depth study after being surprised and intrigued to learn that the issue has received little serious scientific consideration, despite being a concern felt by many men. The study has been published in the journal ‘Trends in Ecology and Evolution.

The researchers hypothesised that 10 per cent of fathers might be affected and said they were pleasantly surprised by the low figure of 2 per cent. Report author Maarten Larmuseau said: “Media and popular scientific literature often claim that many alleged fathers are being cuckolded into raising children who biologically are not their own. Surprisingly, the estimated rates within human populations are quite low- around 1 or 2 percent”

He added that the research debunked sexist social stereotypes that heterosexual women feel an evolutionary imperative to have multiple male partners to increase fertility rates but do not inform the partners, to avoid confrontation. Mr Larmuseau said: “The observed low cuckoldry rates in contemporary and past human populations clearly challenge the well-known idea that women routinely ‘shop around’ for good genes by engaging in extra-pair copulations to obtain genetic benefits for their children.”
