Revolutionizing Species Classification: The DNA Barcoding Project

The video discusses the evolution of species classification from the Linnaean system to DNA barcoding. The Linnaean system, developed in the 18th century, groups organisms based on shared characteristics. However, DNA barcoding offers a more objective method by using mitochondrial DNA as a species identifier. This new system, coordinated by the Consortium for the Barcode of Life, has shown errors in the traditional system through pilot projects. DNA barcoding simplifies species identification by analyzing a specific gene sequence, even applicable to some extinct species. The method is cost-effective and quick, revolutionizing biological classification.
