DNA provided Neanderthals with advantages as they adapted to new environments, however they also brought negative consequences – and nicotine addiction was among the downsides of some genes.

There are six key indicators that show you have Neanderthal DNA, genetic experts say. 

Up to two per cent of our DNA comes from our ancient predecessors. Around 60,000 years ago and Africa and Asia interbreeding happened with Neanderthals.

Sebnem Unluisler, a genetic engineer, says genes impacted everything from the colour of hair to nicotine addiction among humans nowadays. Unluisler, of the London Regenerative Institute said: “Neanderthal DNA represents only a small percentage of the modern human genome, and these influences are just one piece of the genetic puzzle that makes each person unique.” There are six unique characteristics that show we’ve still got some Neanderthal DNA.

Hair

Modern humans with thick, straight hair may also have Neanderthal DNA and some people with Neanderthral DNA may have this trait. Studies have also shown red hair was common among their ancient predecessors.
