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:

—Thomas Henry Huxley (1825–95)
“in the absence of feet, “a method of conclusions”;
“a knowledge of principles,”
in the curious phenomenon of your occipital horn.”
