Kutholwe into emangalisayo ekujuleni koLwandle iBaltic! Ososayensi bazithele phezu kwesakhiwo esikhulu esingaphansi kwamanzi esakhiwa eminyakeni engaphezu kuka-10,000 edlule. Le megastructure, okukholakala ukuthi ingelinye lamathuluzi okuzingela amadala enziwe abantu eYurophu, yakhiwa abazingeli be-Stone Age.
Cabanga ngomugqa owelula cishe ikhilomitha ukusuka olwandle – leso yisilinganiso salokhu okutholakele okumangalisayo. Iqanjwe abacwaningi ngokuthi “i-Blinkerwall”, yenziwe cishe ngamatshe angu-1,500 namatshe ahlelwe kahle ngokulandelana. Lolu donga lwangaphansi kwamanzi alwakhelwe ukuhlobisa; kukholakala ukuthi ibambe iqhaza elibalulekile endleleni yokuphila yabazingeli.
Kanjani ngempela? Abacwaningi bacabanga ukuthi bekuyingxenye yesu eliwubuciko lokuzingela. Ama-reindeer, okuwumthombo wokudla okuyisisekelo kulaba bantu bokuqala, cishe ayeluswe ngasodongeni. Kungenzeka ukuthi umugqa wamatshe wawuyisithiyo noma ifaneli, okwenza kube lula kubazingeli ukuba bathathe inyamazane yabo.
Lokhu kutholwa akukhona nje ngodonga olupholile olungaphansi kwamanzi. Ikhanyisa ngobuhlakani kanye nobuchule bemiphakathi ye-Stone Age. I-Blinkerwall ikhuluma kakhulu ngemikhuba yabo yokuzingela eyinkimbinkimbi, ukuziphatha kwendawo, kanye nekhono labo lokuhlela nokusebenza ndawonye.
Ukuthola izimfihlo ze-Blinkerwall kusanda kuqala. Uphenyo olwengeziwe luthembisa ukunikeza amazwibela athakazelisayo ezimpilweni zalaba bazizingeli basendulo kanye nendlela ababezivumelanisa ngayo nendawo yabo.
