History
Archeological work has revealed that Xenicus lyalli was widespread on the main islands of New Zealand in earlier times. Its disappearance from there was probably due to predation by the kiore (Polynesian Rat, Rattus exulans), which may have been introduced by the Māori. The presence of a flightless bird on an island separated from the mainland by 3.2 km may seem puzzling, along with the presence of Hamilton's frog (which is killed by exposure to salt water). One possibility is that rafts of vegetable matter allowed them to cross, although the absence of kiore would then be surprising. Stephens Island, along with the other islands in the Marlborough Sounds, was joined to the mainland during the last ice age due to the lower sea level, so the native animals may have arrived then.

Famous quotes containing the word history:
“If you look at history you’ll find that no state has been so plagued by its rulers as when power has fallen into the hands of some dabbler in philosophy or literary addict.”
—Desiderius Erasmus (c. 1466–1536)
“The principle that human nature, in its psychological aspects, is nothing more than a product of history and given social relations removes all barriers to coercion and manipulation by the powerful.”
—Noam Chomsky (b. 1928)
“Don’t give your opinions about Art and the Purpose of Life. They are of little interest and, anyway, you can’t express them. Don’t analyse yourself. Give the relevant facts and let your readers make their own judgments. Stick to your story. It is not the most important subject in history but it is one about which you are uniquely qualified to speak.”
—Evelyn Waugh (1903–1966)
