Question: when did the origin country for the term pop music take control of where most australopithecus were found?

<P0-S0> The Oxford Dictionary of Music states that while pop's ``earlier meaning meant concerts appealing to a wide audience... since the late 1950s, however, pop has had the special meaning of non-classical mus (ic), usually in the form of songs, performed by such artists as the Beatles, the Rolling Stones, ABBA, etc ''. <P0-S1> According to the website of The New Grove Dictionary of Music and Musicians, called Grove Music Online, the term ``pop music ''`` originated in Britain in the mid-1950s as a description for rock and roll and the new youth music styles that it influenced''. <P0-S2> Grove Music Online also states that``... in the early 1960s, (the term) 'pop music' competed terminologically with beat music (in England), while in the USA its coverage overlapped (as it still does) with that of 'rock and roll'''. <SEP> <P1-S0> a cappella [a kapˈpɛlla] (italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. <P1-S1> it contrasts with cantata, which is accompanied singing. <P1-S2> the term "a cappella" was originally intended to differentiate between renaissance polyphony and baroque concertato style. <P1-S3> in the 19th century a renewed interest in renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. <P1-S4> the term is also used, albeit rarely, as a synonym for alla breve. <SEP> <P2-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. <P2-S1> The country became a self - governing nation state within the British Empire, in 1934 following enactment of the Status of the Union Act. <P2-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. <P2-S3> A republican constitution was adopted. <SEP> <P3-S0> the oldest hominin sites are in east africa. <P3-S1> the earliest known retouched tools were found in lomekwi, kenya, and date back to 3.3 ma, in the late pliocene. <P3-S2> they might be the product of australopithecus garhi or paranthropus aethiopicus, the two known hominins contemporary with the tools. <SEP> <P4-S0> It is now called ``Little Foot ''and it is probably around three million years old. <P4-S1> Then, in 1997, an almost complete Australopithecus skeleton with skull was found in the Sterkfontein caves of Gauteng, South Africa. <P4-S2> It was named Australopithecus prometheus which has since been placed within A. africanus. <P4-S3> Other fossil remains found in the same cave in 2008 were named Australopithecus sediba, which lived 1.9 million years ago. <P4-S4> A. africanus probably evolved into A. sediba, which some scientists think may have evolved into H. erectus, though this is heavily disputed.
