However, the significance of Neanderthal or Denisovan genetic variants on disease risk is still an area of active study, and most direct-to-consumer test results currently do not include them.

For now, knowing which specific genetic variants a person inherited from Neanderthal or Denisovan ancestors provides only limited information about a few physical traits. A high-coverage genome sequence from an archaic Denisovan individual.

Epub Aug The diverse origins of the human gene pool. Nat Rev Genet. PubMed: Neanderthal genomic landscape of Neanderthal ancestry in present-day humans. It may seem strange that we inherited disease-causing genes at all. After all, only beneficial genes should survive, so surely over hundreds of generations we should have shaken off these unwanted contributions? Consider the gene Neanderthal that contribute to the prevalence of type 2 diabetes in Western societies, where people rarely go hungry.

When we were hunter-gatherers, it was normal practice to go for days without eating, says Carles Lalueza-Fox of Pompeu Fabra University in Barcelona, Spain. That means our genes must have evolved to cope with numerous bouts of near-starvation and occasional days when food was plentiful. If that's true, it is no surprise that Neanderthal genes have now taken a darker turn.

We didn't evolve to gorge on food every day, which is why these same genes can cause havoc. View image of Red hair may have been prevalent Credit: Dpa picture alliance archive.

It's harder to explain the gene that makes us prone to tobacco addiction. Not only were there no cigarettes, tobacco is native to North America and nobody lived there during Neanderthal times. However, the mutation could have had Neanderthal function in the past, perhaps relating to the brain receptors that sense nicotine.

Or it could simply be a fluke. The Neanderthal-human sex happened just over 1, generations ago, which is hardly any time. It might look different a million years from now. Fortunately, it's not all bad news. As well as our keratin-enriched sequences, we also Neanderthal to have inherited some genes that boost our immune systems.

When modern humans left Africa and arrived in Europe, they would have encountered all sorts of unfamiliar diseases that they had no immunity to. However, Neanderthals had been in Europe over a hundred thousand years, so they had probably adapted to the local diseases, Neanderthal.

The offspring of humans and Neanderthals would have inherited some of these adaptations, helping them survive. View image of We have long been interested in the appearance of our extinct cousins Credit: Alamy.

For now it is difficult to pinpoint what my 2. The reason is simple: our understanding of genetics remains limited. Humans have over 25, genes, and we have no idea what most of them do. The problem is made trickier because different people carry different bits of Neanderthal DNA. There may not be any cases where "a single Neanderthal gene is so great that all modern humans today would carry it," says Jean-Jacques Hublinalso of the Max Planck Institute for Evolutionary Anthropology.

Hublin thinks "great Neanderthal genes" do not exist, and that their contribution to our genome is inconsequential. Instead, modern human genes have completely swamped theirs. Akey disagrees. He says that, when you look at how much Neanderthal DNA exists around the world, it's clear they have have made a small but significant contribution to Neanderthal pool of genes that influence disease".

The Neanderthal DNA is also a guide to what makes our species unique. By pinpointing the places where it is absent, we can identify genes that only our species has developed, says Akey.
