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:
“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends portraits hang and look thereon;
Irelands history in their lineaments trace;
Think where mans glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (18651939)
“The disadvantage of men not knowing the past is that they do not know the present. History is a hill or high point of vantage, from which alone men see the town in which they live or the age in which they are living.”
—Gilbert Keith Chesterton (18741936)
“Books of natural history aim commonly to be hasty schedules, or inventories of Gods property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.”
—Henry David Thoreau (18171862)
