The Barcode of Life
February 12, 2005 8:14 PM Subscribe
The Barcode of life is a short DNA sequence, from a uniform locality on the genome, used for identifying species. This can revolutionize taxonomy, if more people join the consortium and more species are added to the database. This device would be a biologist's Uber-pony. (via World Changing)
I attended a talk given by Dr. Hebert, one of the proponents of the barcode project (some papers here and here) and it is certainly an exciting development.
However, some members of the field are concerned that scientists will rely on the barcode results to define species, instead of using it along with existing knowledge about the biology and ecology of species to define species. Defining a species based on the sequence of a single gene is generally considered to be insufficient, so it will be important to closely observe how this technology is used.

meanwhile, if you search the front page for "barcode".... what's with the pseudo-double posts about DNA?
