DNA barcoding aims to protect species, food

A handout combination image shows a barn owl (Tyto alba), the most widely distributed species of owl, and one of the most widespread of all birds and its DNA barcode. Every species, from extinct to thriving, is set to get its own DNA barcode in an attempt to better track the ones that are endangered, as well as those being shipped across international borders as food or consumer products.
