Question: A relative of the emu is native to which continent?

Context:
Military history of North America
The Military history of North America can be viewed as having four distinct phases.
 The first is the precolonial period, during which warfare and conquest occurred from time to time between Native American tribes and alliances.
 The second is the colonial period following the European discovery of the continent, during which the region saw both European efforts to wrest territories from their native inhabitante, and where European nations used their North American colonial possessions to wage wars with one another for the control of resources.
 This phase culminated in the American Revolution, with the continent thereafter shifting away from European military domination.
 The third phase was one of internal discord on the continent, including skirmishes between the United States and Canada, the Mexican–American War, the American Civil War and similar internal violence in Mexico, the Indian Wars, and the expulsion of the last major colonial bastion in the Spanish–American War.
King Island emu
The King Island emu ("Dromaius novaehollandiae minor") is an extinct subspecies of emu that was endemic to King Island, which is situated in the Bass Strait between mainland Australia and Tasmania.
 Its closest relative may be the extinct Tasmanian emu ("D. n. diemenensis"), as they belonged to a single population until less than 14,000 years ago, when Tasmania and King Island were still connected.
 The small size of the King Island emu may be an example of insular dwarfism.
Mental mapping
In behavioral geography, a mental map is a person's point-of-view perception of their area of interaction.
 Although this kind of subject matter would seem most likely to be studied by fields in the social sciences, this particular subject is most often studied by modern day geographers.
 They study it to determine subjective qualities from the public such as personal preference and practical uses of geography like driving directions.
 Mass media also have a virtually direct effect on a person's mental map of the geographical world.
 The perceived geographical dimensions of a foreign nation (relative to one's own nation) may often be heavily influenced by the amount of time and relative news coverage that the news media may spend covering news events from that foreign region.
 For instance, a person might perceive a small island to be nearly the size of a continent, merely based on the amount of news coverage that he or she is exposed to on a regular basis.
Bush tucker
Bush tucker, also called bushfood, is any food native to Australia and used as sustenance by the original inhabitants, the Aboriginal Australians, but it can also describe any native fauna or flora used for culinary and/or medicinal purposes, regardless of the continent or culture.
 Examples of Australian native animal foods (meats) include kangaroo, emu and crocodile.
 In particular, kangaroo is quite common and can be found in Australian supermarkets, often cheaper than beef.
 Other animals, for example goanna and witchetty grubs, were eaten by Aboriginal Australians.
 Fish and shellfish are culinary features of the Australian coastal communities.
Emu
The emu ("Dromaius novaehollandiae") is the second-largest living bird by height, after its ratite relative, the ostrich.
 It is endemic to Australia where it is the largest native bird and the only extant member of the genus "Dromaius".
 The emu's range covers most of mainland Australia, but the Tasmanian emu and King Island emu subspecies became extinct after the European settlement of Australia in 1788.
 The bird is sufficiently common for it to be rated as a least-concern species by the International Union for Conservation of Nature.
Podocarpus drouynianus
Podocarpus drouynianus is a species of podocarp native to the relatively high rainfall southwestern corner of Western Australia, where it is known by the name emu berry, wild plum or native plum although it is not a true plum.
 The Noongar name for the plant is koolah.
Fauna of Australia
The fauna of Australia consists of a huge variety of animals; some 83% of mammals, 89% of reptiles, 24% of fish and insects and 93% of amphibians that inhabit the continent are endemic to Australia.
 This high level of endemism can be attributed to the continent's long geographic isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time.
 A unique feature of Australia's fauna is the relative scarcity of native placental mammals.
 Consequently, the marsupials — a group of mammals that raise their young in a pouch, including the macropods, possums and dasyuromorphs — occupy many of the ecological niches placental animals occupy elsewhere in the world.
 Australia is home to two of the five known extant species of monotremes and has numerous venomous species, which include the platypus, spiders, scorpions, octopus, jellyfish, molluscs, stonefish, and stingrays. Uniquely, Australia has more venomous than non-venomous species of snakes.
Apparent polar wander
Apparent polar wander (APW) is the perceived movement of the Earth's paleo-magnetic poles relative to a continent while regarding the continent being studied as fixed in position.
 It is frequently displayed on the present latitude-longitude map as a path connecting the locations of geomagnetic poles, inferred at distinct times using paleomagnetic techniques.
Black honeyeater
The black honeyeater ("Sugomel nigrum") is a species of bird in the family of honeyeaters, Meliphagidae, and the sole species in the genus "Sugomel".
 The black honeyeater exhibits sexual dimorphism with the male being black and white while the female is a speckled grey-brown; immature birds look like the female.
 The species is endemic to Australia, and ranges widely across the arid areas of the continent, through open woodland and shrubland, particularly in areas where the emu bush and related species occur.
Common ostrich
The ostrich or common ostrich ("Struthio camelus") is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus "Struthio", which is in the ratite family.
 In 2014, the Somali ostrich ("Struthio molybdophanes") was recognized as a distinct species.

Answer: Africa
