The University of Windsor in Canada: paedophiles

Paedophiles could be spotted using a check-list of physical signs - including being left-handed, having misshapen ears and being smaller than average. 

Researchers have suggested that paedophilia could be a biological problem, with physical manifestations. 

It could even be possible to apprehend paedophiles before they offend, using these ‘warning signs’. 

The new research, by the University of Windsor in Canada, found that paedophiles are more likely to have minor physical abnormalities such as misshapen ears and a high palate.
