Question: When did the country that became a dominant European power after the seven years' war take control of the country yielding the most Australopithecus fossils?

<P0-S0> Although Anglo - French skirmishes over their American colonies had begun with what became the French and Indian War in 1754, the large - scale conflict that drew in most of the European powers was centered on Austria's desire to recover Silesia from the Prussians. <P0-S1> Seeing the opportunity to curtail Britain's and Prussia's ever - growing might, France and Austria put aside their ancient rivalry to form a grand coalition of their own, bringing most of the other European powers to their side. <P0-S2> Faced with this sudden turn of events, Britain aligned itself with Prussia, in a series of political manoeuvres known as the Diplomatic Revolution. <P0-S3> However, French efforts ended in failure when the Anglo - Prussian coalition prevailed, and Britain's rise as among the world's predominant powers destroyed France's supremacy in Europe, thus altering the European balance of power. <SEP> <P1-S0> at the end of the balkan wars, the extent of greece's territory and population had increased. <P1-S1> in the following years, the struggle between king constantine i and charismatic prime minister eleftherios venizelos over the country's foreign policy on the eve of world war i dominated the country's political scene, and divided the country into two opposing groups. <P1-S2> during parts of the first world war, greece had two governments; a royalist pro-german government in athens and a venizelist pro-britain one in thessaloniki. <P1-S3> the two governments were united in 1917, when greece officially entered the war on the side of the triple entente. <SEP> <P2-S0> the punic wars were a series of three wars fought between rome and carthage from 264 bc to 146 bc. <P2-S1> at the time, they were one of the largest wars that had ever taken place. <P2-S2> the term punic comes from the latin word punicus (or poenicus), meaning ``carthaginian '', with reference to the carthaginians' phoenician ancestry. <P2-S3> the main cause of the punic wars was the conflicts of interest between the existing carthaginian empire and the expanding roman republic. <P2-S4> the romans were initially interested in expansion via sicily (which at that time was a cultural melting pot), part of which lay under carthaginian control. <P2-S5> at the start of the first punic war, carthage was the dominant power of the western mediterranean, with an extensive maritime empire. <P2-S6> rome was a rapidly ascending power in italy, but it lacked the naval power of carthage. <P2-S7> by the end of the third war, after more than a hundred years and the loss of many hundreds of thousands of soldiers from both sides, rome had conquered carthage's empire, completely destroyed the city, and become the most powerful state of the western mediterranean. <SEP> <P3-S0> Then, in 1997, an almost complete Australopithecus skeleton with skull was found in the Sterkfontein caves of Gauteng, South Africa. <P3-S1> It is now called ``Little Foot ''and it is probably around three million years old. <P3-S2> It was named Australopithecus prometheus which has since been placed within A. africanus. <P3-S3> Other fossil remains found in the same cave in 2008 were named Australopithecus sediba, which lived 1.9 million years ago. <P3-S4> A. africanus probably evolved into A. sediba, which some scientists think may have evolved into H. erectus, though this is heavily disputed. <SEP> <P4-S0> 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. <P4-S1> The country became a self - governing nation state within the British Empire, in 1934 following enactment of the Status of the Union Act. <P4-S2> 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. <P4-S3> A republican constitution was adopted.
