Inuk looks like he is from the Johnny Depp 'Imagine You Smell Poo But Don't Know Where It Is' School of Acting.
Willerslev and colleagues, who report their findings tomorrow in Nature, went to great lengths to show that the sample was not contaminated by modern DNA--a concern because the hair had been handled by archaeologists and stored in a museum. Hair, which is nonporous, is ideal: "All the contamination is on the surface, so it's quite easy to get rid of," says Morten Rasmussen, another researcher on the team.
To verify that the sample was contamination-free, the researchers looked for traces in the genetic code of genes that appear only in European populations. They found none, showing that the DNA inside the hair shaft was pure. "They did everything they could to show the sequence was good," says Beth Shapiro, a biologist at Pennsylvania State University, University Park. "It's a beautiful sample."
