Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge?
And who would have thought to trawl through five million of these gene snapshots—called "DNA barcodes"—collected from 100,000 animal species by hundreds of researchers around the world and deposited in the US government-run GenBank database?
That would be Mark Stoeckle from The Rockefeller University in New York and David Thaler at the University of Basel in Switzerland, who together published findings last week sure to jostle, if not overturn, more than one settled idea about how evolution unfolds.
