<prompt> Fingqa isihloko: Zingezinye zezindawo ezicebe kakhulu emhlabeni kodwa futhi zinzima kakhulu ukuba abantu bahlale kuzo. Manje ososayensi baye bathola ukuthi abantu kungenzeka baqala ukuphila ehlathini lemvula eminyakeni engaba ngu - 20 000 edlule - eminyakeni engu - 12 000 ngaphambili kunalokho okwakulindelekile. Abacwaningi baseNyuvesi yaseOxford bathola ubufakazi obuvalelwe ngaphakathi kwamazinyo abantu atholakala emahlathini emvula aseSabaragamuwa eningizimu yeSri Lanka. Ososayensi baye bathola ukuthi abantu kungenzeka baqala ukuphila ehlathini lemvula eminyakeni engaba ngu-20 000 edlule - eminyakeni engu - 12 000 ngaphambili kunalokho okwakulindelekile. Abacwaningi baseNyuvesi yase-Oxford bathole ubufakazi obuvalelwe ngaphakathi kwamazinyo abantu atholakala emahlathini emvula aseSabaragamuwa eningizimu yeSri Lanka esithombeni. Lolu cwaningo luphinde luphawule ukuthi kunezinkomba zokuthi abantu kungenzeka babehlala emahlathini emvula eminyakeni engaba ngu-45.000 edlule. Ngokososayensi, kungenzeka ukuthi abantu baseNeanderthal bakha futhi bagqoka ubucwebe bokuqala emhlabeni eminyakeni engu - 130 000 edlule. Abacwaningi abahlola izipikili eziyisishiyagalombili ezithathwe ekhozini elinomsila omhlophe elalitholakala eKrapina, eCroatia, bathi zazisetshenziselwa ukwenza umgexo noma isongo. Lezi zinzipho zinezimpawu eziningi zokunqunywa, ama-notch nezimpawu zokuthi zazipholishwa abantu baseNeanderthal ababekade behlala endaweni lapho zatholakala khona. Izazi zezinhlobo zabantu zaseYunivesithi yaseKansas zithi kubonakala sengathi izipikili zazenziwe zaba ubucwebe obungokomfanekiso eminyakeni engu-80 000 ngaphambi kokuba abantu banamuhla bafike eYurophu. Lokhu okutholakele kunezela ebufakazini obandayo bokuthi abantu baseNeanderthal babengebona izidalwa ezinokuqonda okuhamba kancane neziyisisekelo ngokuvamile ezivezwa njengazo. Lokhu okutholakele kuphikisana nombono wokuthi amahlathi emvula asezindaweni ezishisayo ayeyizindawo ezingenabantu kuze kube cishe eminyakeni engu-8.000 edlule. UProfesa Julia Lee - Thorp, isazi semivubukulo eYunivesithi yase - Oxford esasiza ekuqondiseni lolu cwaningo, wathi:Indlela yokusebenzisa i - isotopic esetshenziswe ocwaningweni lwethu isiye yasetshenziswa ngokuphumelelayo ukuze kuhlolwe indlela izilwane ezifuywayo, kuhlanganise nezinkawu ezinkulu zase - Afrika, ezizivumelanisa ngayo nendawo yazo yasehlathini...  <response>: Ososayensi baseNyuvesi yaseOxford bahlaziya ama - isotope emazinyweni abantu basendulo. Lawo mazinyo atholakala emahlathini emvula aseSabaragamuwa eSri Lanka. Abacwaningi bathola ukuthi amazinyo ayengabantu ababedla ukudla kwasehlathini lemvula. Lokhu kusho ukuthi abantu babehlala emahlathini emvula eminyakeni engu - 12 000 ngaphambili kunalokho obekucatshangwa. Amahlathi emvula kwakucatshangwa ukuthi awanabantu kuze kube yiminyaka engu - 8 000 edlule.
