The Field Museum in Chicago preserves everythingbr from fish and snakes to frogs and Komodo dragons inbr their basement.br These 11 million fluid specimens are preserved in jarsbr or tanks. Preparing and storing them is abr centuries-long commitment, so why do it? Thisbr method effectively keeps their shape and, in somebr cases, even DNA. Not only that, but it has helpedbr researchers do groundbreaking work, like developingbr new techniques for getting old DNA and discoveringbr new species right among the shelves.br We went to the Field Museum to see how newbr specimens are added to the ever-growing collection.
