Question: When did the country that controlled the world at the end of the 1800s take control of the country where the most australopithecus fossils have been found?

full_context: Document 1: History of South Africa: Following the defeat of the Boers in the Anglo - Boer or South African War (1899 -- 1902), the Union of South Africa was created as a dominion of the British Empire in terms of the South Africa Act 1909, which amalgamated the four previously separate British colonies: Cape Colony, Natal Colony, Transvaal Colony and Orange River Colony. The country became a self - governing nation state within the British Empire, in 1934 following enactment of the Status of the Union Act. The dominion came to an end on 31 May 1961 as the consequence of a 1960 referendum, which legitimised the country becoming a sovereign state named Republic of South Africa. A republican constitution was adopted.
Document 2: Australopithecus afarensis: Australopithecus afarensis (Latin: ``Southern ape from Afar '') is an extinct hominin that lived between 3.9 and 2.9 million years ago in Africa and possibly Europe. A. afarensis was slenderly built, like the younger Australopithecus africanus. A. afarensis is thought to be more closely related to the genus Homo (which includes the modern human species Homo sapiens), whether as a direct ancestor or a close relative of an unknown ancestor, than any other known primate from the same time. Some researchers include A. afarensis in the genus Praeanthropus.
Document 3: 1960 South African republic referendum: A referendum on becoming a republic was held in South Africa on 5 October 1960. The Afrikaner - dominated right - wing National Party, which had come to power in 1948, was avowedly republican, and regarded the position of Queen Elizabeth II as head of state as a relic of British imperialism. The National Party government subsequently organised the referendum on whether the then Union of South Africa should become a republic. The vote, which was restricted to whites, was narrowly approved by 52.29% of the voters. The Republic of South Africa was constituted on 31 May 1961.
Document 4: British Empire: The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 7001230000000000000 ♠ 23% of the world population at the time, and by 1920, it covered 35,500,000 km (13,700,000 sq mi), 7001240000000000000 ♠ 24% of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase ``the empire on which the sun never sets ''was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.
Document 5: British Empire: Between 1815 and 1914, a period referred to as Britain's "imperial century" by some historians, around 10,000,000 square miles (26,000,000 km2) of territory and roughly 400 million people were added to the British Empire. Victory over Napoleon left Britain without any serious international rival, other than Russia in central Asia. Unchallenged at sea, Britain adopted the role of global policeman, a state of affairs later known as the Pax Britannica, and a foreign policy of "splendid isolation". Alongside the formal control it exerted over its own colonies, Britain's dominant position in world trade meant that it effectively controlled the economies of many countries, such as China, Argentina and Siam, which has been characterised by some historians as "Informal Empire".
Document 6: British Empire: The independence of the Thirteen Colonies in North America in 1783 after the American War of Independence caused Britain to lose some of its oldest and most populous colonies. British attention soon turned towards Asia, Africa, and the Pacific. After the defeat of France in the Revolutionary and Napoleonic Wars (1792 -- 1815), Britain emerged as the principal naval and imperial power of the 19th century. Unchallenged at sea, British dominance was later described as Pax Britannica (``British Peace ''), a period of relative peace in Europe and the world (1815 -- 1914) during which the British Empire became the global hegemon and adopted the role of global policeman. In the early 19th century, the Industrial Revolution began to transform Britain; by the time of the Great Exhibition in 1851 the country was described as the`` workshop of the world''. The British Empire expanded to include most of India, large parts of Africa and many other territories throughout the world. Alongside the formal control that Britain exerted over its own colonies, its dominance of much of world trade meant that it effectively controlled the economies of many regions, such as Asia and Latin America.
Document 7: British Empire: The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1922 the British Empire held sway over about 458 million people, one-fifth of the world's population at the time, and covered more than 13,000,000 sq mi (33,670,000 km2), almost a quarter of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.
Document 8: Union of South Africa: The Union of South Africa (Dutch: Unie van Zuid - Afrika, Afrikaans: Unie van Suid - Afrika) is the historic predecessor to the present - day republic of South Africa. It came into being on 31 May 1910 with the unification of four previously separate British colonies: the Cape, Natal, Transvaal and Orange River colonies. It included the territories formerly part of the Boer republics annexed in 1902, the South African Republic and the Orange Free State.
Document 9: History of South Africa: Following the defeat of the Boers in the Anglo - Boer or South African War (1899 -- 1902), the Union of South Africa was created as a dominion of the British Empire in terms of the South Africa Act 1909, which amalgamated the four previously separate British colonies: Cape Colony, Natal Colony, Transvaal Colony, and Orange River Colony.

Document 10: Australopithecus: Then, in 1997, an almost complete Australopithecus skeleton with skull was found in the Sterkfontein caves of Gauteng, South Africa. It is now called ``Little Foot ''and it is probably around three million years old. It was named Australopithecus prometheus which has since been placed within A. africanus. Other fossil remains found in the same cave in 2008 were named Australopithecus sediba, which lived 1.9 million years ago. A. africanus probably evolved into A. sediba, which some scientists think may have evolved into H. erectus, though this is heavily disputed.
Document 11: South Africa: The name ``South Africa ''is derived from the country's geographic location at the southern tip of Africa. Upon formation the country was named the Union of South Africa in English, reflecting its origin from the unification of four formerly separate British colonies. Since 1961 the long form name in English has been the`` Republic of South Africa''. In Dutch the country was named Republiek van Zuid - Afrika, replaced in 1983 by the Afrikaans Republiek van Suid - Afrika. Since 1994 the Republic has had an official name in each of its 11 official languages.
Document 12: Eritrea: At Buya in Eritrea, one of the oldest hominids representing a possible link between Homo erectus and an archaic Homo sapiens was found by Italian scientists. Dated to over 1 million years old, it is the oldest skeletal find of its kind and provides a link between hominids and the earliest anatomically modern humans. It is believed that the section of the Danakil Depression in Eritrea was also a major player in terms of human evolution, and may contain other traces of evolution from Homo erectus hominids to anatomically modern humans.
Document 13: Lucy (Australopithecus): Lucy is the common name of AL 288 - 1, several hundred pieces of bone fossils representing 40 percent of the skeleton of a female of the hominin species Australopithecus afarensis. In Ethiopia, the assembly is also known as Dinkinesh, which means ``you are marvelous ''in the Amharic language. Lucy was discovered in 1974 in Africa, near the village Hadar in the Awash Valley of the Afar Triangle in Ethiopia, by paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History.

Document 15: Early expansions of hominins out of Africa: The oldest hominin sites are in East Africa. The earliest known retouched tools were found in Lomekwi, Kenya, and date back to 3.3 Ma, in the late Pliocene. They might be the product of Australopithecus garhi or Paranthropus aethiopicus, the two known hominins contemporary with the tools.
