The discovery of so many new species was made possible after analyzing and comparing the DNA genetic "bar codes" of 643 North American bird species."

Nah, not really - with today's technology minute amounts of nuclear material can be amplified by a technique called "Polymerase Chain Reaction" to obtain sufficient DNA to type a person's, or animal's genome. Apparently, the residual saliva on a cigarette butt is adequate. |
