Uhlolisiso lwentonga yokujula eyenziwe ngomthi etsolo-mbini, eyafunyanwa eSchöningen, eJamani kwiminyaka engama-30 eyadlulayo, kwafunyaniswa ukuba yayikhutshiwe, yanongwa yaza yafakwa isanti ngaphambi kokuba isetyenziswe ekuzingeleni izilwanyana. Olu phando luye lwabonisa ukuba abantu bokuqala babenesakhono esiphucukileyo sokwenza umthi kunokuba bekukholelwa ngaphambili.
Uphando lucebisa ukuba ukukwazi ukwenza izixhobo ezikhaphukhaphu kwenza ukuzingela kwezilwanyana ezinobungakanani obuphakathi nobuncinci njengomsebenzi weqela. Ukusebenzisa iintonga zokujula njengesixhobo sokuzingela kwakunokuba sisiganeko esihlangeneyo, kuquka nabantwana.
Uphando lwenziwe nguDkt Annemieke Milks ovela kwiYunivesithi yokuFunda kwiSebe le-Archaeology. Ngokutsho kwakhe, ukutyhilwa kwezixhobo zokhuni ziguqule indlela esizijonga ngayo izenzo zabantu bamandulo. Kuyaphawuleka ukuba aba bantu bangaphambili babenombono omkhulu kunye nobuchule bomthi, bade basebenzise iindlela ezininzi zokwenziwa ngamaplanga ezisasetyenziswa namhlanje.
Amandla okuba uluntu lonke luthathe inxaxheba ekuzingeleni lusenokuba lwandisiwe zezi ntonga zokujula zilula, zilawuleka ngakumbi kunemikhonto enzima. Oku kwakunokwenza abantwana baqhelisele ukujula nokuzingela kunye nabo.
UDirk Leder, omnye wababhali, waphawula ukuba abantu baseSchöningen benza isixhobo se-ergonomic kunye ne-aerodynamic ukusuka kwisebe lespruce. Ukuze bafezekise oku, kwakufuneka bagawule baze bahlube amaxolo, bawamise, bakhuthulule umaleko, bachithe iinkuni ukuze banqande ukuqhekeka okanye ukujija kunye nesanti ukuze kube lula ukuphatha.
Ngo-1994, kwafunyanwa intonga eyi-77cm ubude eSchöningen, kunye nezinye izixhobo ezifana nokujula, imikhonto, kunye nentonga yokujula eyongezelelweyo yobukhulu obufanayo.
Kuphononongo olutsha, intonga yokujula etsolwe kabini yavavanywa ngendlela ecokisekileyo. Esi sixhobo mhlawumbi sanceda abantu bokuqala ekuzingeleni iinyamakazi ezinobukhulu obuphakathi, ezifana nenyama ebomvu kunye nenyamakazi, kunye nezilwanyana ezincinci ezikhawulezayo, eziquka imivundla kunye neentaka, ekwakunzima ukubamba.
Abantu bamandulo basenokuba babekwazi ukugibisela iintonga ngokujikeleza, okufana nebhoomerang, kumgama omalunga neemitha ezingama-30. Nangona ezi zinto bezikhaphukhaphu, zisenokudala iimpembelelo ezibulalayo ngenxa yesantya esiphezulu ebezinokuqaliswa ngaso.
Amanqaku enziwe ngokucokisekileyo kunye nomphandle ophucukileyo, kunye neempawu zokugqoka, zonke zikhomba ukuba esi siqwenga sisetyenziswe ngamaxesha amaninzi, singaveliswa ngokukhawuleza kwaye silibale.
UThomas Terberger, umphandi okhokelayo, wathi iSiseko soPhando saseJamani esixhaswe ngenkxaso-mali yovavanyo olubanzi lwezinto zakudala ezenziwe ngamaplanga eSchöningen zivelise ulwazi olutsha oluluncedo kwaye idatha evuselela ngakumbi malunga nezixhobo zomthi zamandulo kulindeleke kungekudala.
Uphando lwapapashwa kwiphephancwadi PLoS ONE ngoJulayi 19, 2023.
