Method
While the method has its greatest value when extant species are used for bracketing, the method itself does not not require that both bracketing groups have extant members, nor that the species or group to be bracketed is extinct. The only real requisite is that the two bracketing species/groups be better known, with regard to the trait in question, than the species to be bracketed is.

Famous quotes containing the word method:
“In child rearing it would unquestionably be easier if a child were to do something because we say so. The authoritarian method does expedite things, but it does not produce independent functioning. If a child has not mastered the underlying principles of human interactions and merely conforms out of coercion or conditioning, he has no tools to use, no resources to apply in the next situation that confronts him.”
—Elaine Heffner (20th century)
“Government by average opinion is merely a circuitous method of going to the devil; those who profess to lead but in fact slavishly follow this average opinion are simply the fastest runners and the loudest squeakers of the herd which is rushing blindly down to its destruction.”
—Thomas Henry Huxley (1825–95)
“Direct action ... is the logical, consistent method of Anarchism.”
—Emma Goldman (1869–1940)
