Lapho abavubukuli bekwazi ukuhumusha izimpawu zakudala ezidumile ku I-Göbekli Tepe eTurkey, bathola ukuthi leyo mifanekiso eqoshiwe eyinqaba ilandisa ngethonya elibhubhisayo lenkanyezi enomsila eminyakeni engaphezu kuka-13,000 XNUMX edlule.
Ukuhlolisisa umcimbi ngokulingisa kwekhompiyutha Yesistimu Yelanga ngaleso sikhathi, abacwaningi bathola ukuthi imifanekiso eqoshiwe ingachaza umthelela wenkanyezi enomsila owenzeke cishe ngo-10,950 BCE - cishe ngesikhathi esifanayo inkathi yeqhwa encane eyashintsha impucuko unomphela.
Le nkathi yeqhwa encane, eyaziwa ngokuthi i-Younger Dryas, yathatha iminyaka engaba ngu-1,000, futhi ithathwa njengenkathi ebalulekile esintwini ngoba kwakungaleso sikhathi ezolimo kanye nempucuko yokuqala ye-Neolithic yavela ― okungenzeka isabela esimweni sezulu esisha esibandayo. Lesi sikhathi siphinde sahlotshaniswa nokushabalala kwe-woolly mammoth.
Kodwa nakuba i-Younger Dryas ifundwe kahle, akucaci kahle ukuthi yini eyabangela isikhathi. Isiteleka senkanyezi enomsila singenye yemibono ehamba phambili, kodwa ososayensi abakwazanga ukuthola ubufakazi obuphathekayo benkanyezi enomsila kusukela ngaleso sikhathi.
Ithimba labacwaningi abavela eNyuvesi yase-Edinburgh e-UK lithe le mifanekiso eqoshiwe, etholakala endaweni okukholakala ukuthi iyithempeli elidala elaziwayo, i-Göbekli Tepe eningizimu yeTurkey, ikhombisa obunye ubufakazi bokuthi inkanyezi enomsila yabangela i-Younger Dryas.
Ukuhunyushwa kwezimpawu kuphinde kuphakamise ukuthi i-Gobekli Tepe bekungelona nje elinye ithempeli, njengoba kucatshangwa kudala ― kungenzeka ukuthi futhi kwakuyindawo yakudala yokuqapha isibhakabhaka ebusuku. Enye yezinsika zayo ibonakala isebenze njengesikhumbuzo salesi senzakalo esibhubhisayo ― mhlawumbe usuku olubi kakhulu emlandweni kusukela ekupheleni kwe-Ice Age.
I-Gobekli Tepe kucatshangwa ukuthi yakhiwa cishe ngo-9,000 BCE - cishe iminyaka engu-6,000 ngaphambi kwe-Stonehenge - kodwa izimpawu ezisensikeni zidethi umcimbi cishe eminyakeni eyizi-2,000 ngaphambi kwalokho. Futhi insika okwatholakala kuyo okuqoshiwe yaziwa ngokuthi i-Vulture Stone (esithombeni ngezansi) futhi ikhombisa izilwane ezihlukene ezindaweni ezithile ezizungeze itshe.
Lezi zimpawu kwase kuyisikhathi eside zibadida ososayensi, kodwa manje abacwaningi sebethole ukuthi empeleni zazihambisana namaqoqo ezinkanyezi, futhi zabonisa uquqaba lwezingcezu zenkanyezi enomsila ezishaya uMhlaba. Isithombe sendoda engenakhanda etsheni naso kucatshangwa ukuthi sifanekisela inhlekelele yomuntu kanye nokulahlekelwa okukhulu kokuphila kulandela umthelela.
Imidwebo ibonisa izimpawu zokunakekelwa abantu base-Göbekli Tepe iminyaka eyinkulungwane, okubonisa ukuthi umcimbi osichazayo kungenzeka ube nemithelela ehlala isikhathi eside empucukweni.
Ukuzama ukuthola ukuthi leso siteleka senkanyezi enomsila senzeke ngempela noma cha, abacwaningi basebenzisa amamodeli ekhompiyutha ukufanisa amaphethini ezinkanyezi anemininingwane yeVulture Stone ngosuku oluthile ― bathola ubufakazi bokuthi umcimbi okukhulunywa ngawo wawuzokwenzeka cishe ngo-10,950. BCE, nika noma thatha iminyaka engama-250.
Akukhona lokho kuphela, ukuqokwa kwale midwebo kuphinde kufane neqhwa elithathwe eGreenland, elikhomba isikhathi se-Younger Dryas njengoba siqala cishe ngo-10,890 BCE.
Lesi akusona isikhathi sokuqala imivubukulo yasendulo ihlinzeka esikhathini esidlule sempucuko. Ama-paleolithic amaningi imidwebo emigedeni nezinto zobuciko ezinezimpawu zezilwane ezifanayo nezinye izimpawu eziphindaphindiwe ziphakamisa ukuthi isayensi yezinkanyezi ingaba yakudala kakhulu.
