Dec. 30, 2013 — DNA barcoding is used as an effective tool for both the identification of known species and the discovery of new ones. The core idea of DNA barcoding is based on the fact that just a small portion of a single gene already can show that there is less variation between the individuals of one species than between those of several species.
Thus, when comparing two barcode sequences one can establish whether these belong to one single species (viz. when the amount of variation falls within the 'normal' range of the taxon under consideration and below a certain threshold level) or possibly to two species (when the amount exceeds this level).
