Question: When did the country concerned with Russia capturing Constantinople take control of the country where the most australopithecus fossils have been found?

full_context: Document 1: 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 2: Crimean War: The Allies had had time to consider the problem. The French being brought around to agree that the key to the defence was the Malakoff.:441 Emphasis of the siege at Sevastopol shifted to the British left, against the fortifications on Malakoff hill.:339 In March, there was fighting by the French over a new fort being built by the Russians at Mamelon, located on a hill in front of the Malakoff. Several weeks of fighting saw little change in the front line, and the Mamelon remained in Russian hands.
Document 3: Crimean War: France used the right moment and occupied Alger in 1830. In 1831 Muhammad Ali of Egypt, who was the most powerful vassal of the Ottoman Empire, claimed independence. Ottoman forces were defeated in a number of battles, and Egyptians were ready to capture Constantinople, which forced the sultan Mahmud II to seek for Russian military aid. 10 000 Russian army corps landed on the Bosphorus shores in 1833 and helped to prevent the capture of Constantinople, thus the possible disappearance of the Ottoman Empire was prevented.
Document 4: 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 5: Crimean War: Nicholas felt that, because of Russian assistance in suppressing the Hungarian revolution of 1848, Austria would side with him, or at the very least remain neutral. Austria, however, felt threatened by the Russian troops in the Balkans. On 27 February 1854, the United Kingdom and France demanded the withdrawal of Russian forces from the principalities; Austria supported them and, though it did not declare war on Russia, it refused to guarantee its neutrality. Russia's rejection of the ultimatum caused the UK and France to enter the war.
Document 6: 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 7: 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 8: 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 9: 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 10: 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.
Document 11: Crimean War: Britain was concerned about Russian activity and Sir John Burgoyne senior advisor to Lord Aberdeen urged that the Dardanelles should be occupied and throw up works of sufficient strength to block any Russian move to capture Constantinople and gain access to the Mediterranean Sea. The Corps of Royal Engineers sent men to the Dardanelles while Burgoyne went to Paris, meeting the British Ambassador and the French Emperor. The Lord Cowley wrote on 8 February to Burgoyne "Your visit to Paris has produced a visible change in the Emperor's views, and he is making every preparation for a land expedition in case the last attempt at negotiation should break down.":411
Document 12: 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 13: Crimean War: During this period, the Russian Black Sea Fleet was operating against Ottoman coastal traffic between Constantinople (currently named Istanbul) and the Caucasus ports, while the Ottoman fleet sought to protect this supply line. The clash came on 30 November 1853 when a Russian fleet attacked an Ottoman force in the harbour at Sinop, and destroyed it at the Battle of Sinop. The battle outraged opinion in UK, which called for war. There was little additional naval action until March 1854 when on the declaration of war the British frigate Furious was fired on outside Odessa harbour. In response an Anglo-French fleet bombarded the port, causing much damage to the town. To show support for Turkey after the battle of Sinop, on the 22th of December 1853, the Anglo-French squadron entered the Black Sea and the steamship HMS Retribution approached the Port of Sevastopol, the commander of which received an ultimatum not to allow any ships in the Black Sea.
Document 14: 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 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 15: 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.
