Both investigations were carried out through DNA analysis of fish tissue performed in a laboratory using a U.S. Food and Drug Administration protocol that originated largely at the Smithsonian’s National Museum of Natural History. DNA from the fish in question was identified by matching it against a database of DNA fish barcodes that again, has its origins at the Smithsonian.
