I-10,000 leminyaka yobudala eliMsterious Megastructure yembiwa phantsi koLwandle lweBaltic

I-megastructure engaqondakaliyo eneminyaka eyi-10,000 ubudala yafunyanwa phantsi koLwandle lweBaltic

Ngaphantsi koLwandle lweBaltic kukho indawo yokuzingela yakudala! Abantywili baye bafumanisa isakhiwo esikhulu, esingaphezu kweminyaka eyi-10,000 ubudala, siphumle kubunzulu beemitha ezingama-21 kulwandle lwaseMecklenburg Bight kuLwandle lweBaltic. Oku kufunyanwa kungakholelekiyo sesinye sezixhobo zokuqala ezaziwayo zokuzingela ezakhiwa ngabantu eYurophu.

Kufunyenwe into engakholelekiyo enzulwini yoLwandle lweBaltic! Oosonzululwazi baye bakhubeka kulwakhiwo olukhulu olungaphantsi kwamanzi olwaqala kwiminyaka eyi-10,000. Esi sakhiwo, ekukholelwa ukuba sesona sixhobo sidala sokuzingela esenziwe ngabantu eYurophu, sakhiwa ngabazingeli be-Stone Age.

I-megastructure engaqondakaliyo eneminyaka eyi-10,000 ubudala yafunyanwa phantsi koLwandle lweBaltic 1 — Imodeli ye-3D yecandelo elifutshane le-stonewall njengoko livela ngoku phantsi koLwandle lweBaltic. Ikhredithi yoMfanekiso: Philipp Hoy, iYunivesithi yaseRostock / imodeli: Jens Auer, LAKD MV

Yiba nomfanekiso-ngqondweni womgca owolula phantse ikhilomitha ukunqumla ulwandle – lowo ngumlinganiselo wale nto imangalisayo ifunyenweyo. Ithiywe ngokuba yi "Blinkerwall" ngabaphandi, yenziwe malunga namatye ayi-1,500 kunye namatye acwangciswe ngobuchule ngokulandelelana. Olu donga lwangaphantsi kwamanzi alwakhelwanga ukuhombisa; kukholelwa ukuba idlale indima ebalulekileyo kwindlela yokuphila yabazingeli.

I-megastructure engaqondakaliyo eneminyaka eyi-10,000 ubudala yafunyanwa phantsi koLwandle lweBaltic 2 — I-morphology ye-Undersea yommandla, eqokelelwe kusetyenziswa isithuthi esikude. Kumfanekiso wesi-3, iintolo ezimhlophe zikhomba kwiBlinkerwall. Ityala loMfanekiso: Geersen et al., PNAS (2024)

Njani kanye? Abaphandi bacinga ukuba yayiyinxalenye yeqhinga lokuzingela. Iinyamakazi, eyona nto iphambili ekutyeni kwaba bantu bamandulo, kusenokwenzeka ukuba zazifunqulwe ngaseludongeni. Umgca wamatye unokuba usebenze njengomqobo okanye i-funnel, okwenza kube lula kubazingeli ukuba bathathe amaxhoba abo.

Oku kufunyenweyo akukhona nje ngodonga olupholileyo lwangaphantsi kwamanzi. Inika ukukhanya kubuchule kunye nobuchule bemibutho yeStone Age. I-Blinkerwall ithetha ngokubanzi malunga nezenzo zabo zokuzingela eziyinkimbinkimbi, ukuziphatha kwendawo, kunye nokukwazi kwabo ukulungelelanisa nokusebenza kunye.

Ukutyhila iimfihlo zeBlinkerwall kusanda kuqala. Uphando olongezelelekileyo luthembisa ukunika umbono onika umdla kubomi baba bazingeli bamandulo kunye nendlela ababeziqhelanisa ngayo nendawo abahlala kuyo.
