London - Smokers who just can’t quit the habit may now have the perfect excuse – it’s all the fault of their inner caveman.

DNA found in people who struggle to give up was passed on to us by our Neanderthal cousins, scientists believe.

The two populations are thought to have interbred between 40,000 and 80,000 years ago, after modern humans left Africa for Europe and Asia.

Harvard University researchers made the discovery after comparing the DNA of about 1,000 people with the genetic code of a 50,000 year-old Neanderthal.

But anyone imagining our caveman cousins puffing away could be disappointed.
