DNA Bar-Coding Aims To Protect Endangered Species

DNA barcodes are now believed to help track endangered species and those smuggled to other countries as food or consumer products. They now plan to use make specific International Barcode of Life Project (iBOL) by fragments of DNA extracted from a standardized region of tissue. It is now said to be the world's first reference library of DNA barcodes and the largest biodiversity genomics project. 

The assistant professor of molecular ecology at the University of Guelph's Biodiversity Institute of Ontario Alex Smith explained his vision in these words: "What we're trying to do is to create this global library of DNA barcodes -- snippets, little chunks of DNA -- that permit us to identify species."

Scientists believe that all species, from extinct to thriving, will eventually get their own DNA barcode, later which can be hopefully one day read by handheld mobile devices. A library will be made initially containing than 87,000 formally described species with filed barcodes and more than 1 million total barcoded specimens. Moreover, the barcode will be viewable within a week registering free at the website called boldsystems.org, which is  the website for Barcode of Life Datasystems (BOLD).

"Most of life on the planet is not polar bears and Siberian tigers -- most of life on the planet weighs less than a gram, is less than a centimeter long, and isn't visual,” Smith said adding “It experiences the world through taste and smell and we're not aware of its existence."

It is believed that it will take hard work of 20 years till eventually the Canada-based iBOL barcode’s all 10 million species of multicellular life.
