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:
“Protestantism has the method of Jesus with His secret too much left out of mind; Catholicism has His secret with His method too much left out of mind; neither has His unerring balance, His intuition, His sweet reasonableness. But both have hold of a great truth, and get from it a great power.”
—Matthew Arnold (1822–1888)
““I have usually found that there was method in his madness.”
“Some folk might say there was madness in his method.””
—Sir Arthur Conan Doyle (1859–1930)
