Akatswiri ofukula zinthu zakale ku China apeza zinthu zochititsa chidwi zomwe zingasinthe kamvedwe kathu ka masewera akale a m'nyengo yozizira. Maseti awiri otsetsereka oundana a mkuwa apezeka ku Xinjiang Uyghur Autonomous Region ku China, zomwe zikuwonetsa kuti anthu amawoloka m'nyanja ndi mitsinje yowuma zaka 3,500 zapitazo. Kupeza kodabwitsa kumeneku kukuwunikiranso mbiri yamasewera otsetsereka pamadzi oundana komanso kumapereka chithunzithunzi chochititsa chidwi cha moyo wa anthu akale achi China.
Ma skate, omwe amapangidwa ndi mafupa, amakhulupirira kuti amagwiritsidwa ntchito pazinthu zothandiza komanso zosangalatsa. Amakhala ndi mawonekedwe amakono ndipo ayenera kuti amamangidwa kumapazi ndi zomangira zachikopa. Kupeza kumeneku ndi umboni waluso ndi luso la makolo athu, ndipo ndizosangalatsa kulingalira momwe masewera a m'nyengo yozizira amayenera kuwoneka mu Bronze Age.
Malinga ndi Sayansi Yamoyo lipoti, masewera otsetsereka oundana azaka 3,500 apezeka m'manda a Goaotai Ruins kumadzulo kwa Xinjiang Uyghur Autonomous Region ku China. Mabwinja a Goaotai, omwe amaganiziridwa kuti ankakhala ndi oweta ng'ombe za chikhalidwe cha Andronovo, amakhala ndi malo okhala ndi manda otetezedwa bwino ozunguliridwa ndi nsanja ya miyala ya miyala. Akatswiri ofukula zinthu zakale amaganiza kuti malowa ndi a zaka pafupifupi 3,600 zapitazo.
Zopangidwa kuchokera ku mafupa owongoka otengedwa kuchokera ku ng'ombe ndi akavalo, ma skate amakhala ndi mabowo kumbali zonse ziwiri kuti amangirire "tsamba" lathyathyathya ku nsapato. Ruan Qiurong wa Xinjiang Institute of Cultural Relics and Archaeology adati masiketiwo ndi ofanana ndendende ndi ma skate azaka 5,000 omwe adapezeka ku Finland, ndipo atha kuwonetsa kusinthana kwamalingaliro munthawi ya Bronze Age.
Manda a Goaotai amaganiziridwa kuti anali a banja lolemekezeka pakati pa anthu oyambirira oweta ng'ombe m'deralo, mmodzi mwa ofufuzawo adanena; ndi kuti zofukulidwa kumeneko zavumbula mbali zofunika za miyambo ya maliro awo, zikhulupiriro ndi chikhalidwe chawo.
“Zinthu zina za m’mandamo, kuphatikizapo nsonga yooneka ngati ray yopangidwa kuchokera ku mizere 17 ya miyala, zimasonyeza chikhulupiriro chotheka cha kulambira dzuŵa,” anatero wofufuzayo.
Akatswiri ofukula zinthu zakale anapezanso zotsalira za ngolo zambiri zamatabwa kapena ngolo zomwe zikuoneka kuti zinagwiritsidwa ntchito pomanga manda. Zina mwa mawilo olimba a matabwa 11 ndi matabwa opitirira 30, kuphatikizapo mizati ndi mizati.
Ma skate ofanana ndi otsetsereka a mafupa omwe amapezeka ku Goaotai Ruins apezeka m'malo ofukula zakale kumpoto kwa Europe. Asayansi akuganiza kuti ma skate awa ankagwiritsidwa ntchito ndi anthu akale m'madera ambiri afulati, omwe anali ndi nyanja zazing'ono zikwi makumi ambiri zomwe zimaundana m'nyengo yozizira.
Kupatula izi, dera lamapiri ku China la Xinjiang litha kukhalanso malo obadwirako ski, malinga ndi The New York Times. Zithunzi zakale za m’mapanga m’mapiri a Altai kumpoto kwa Xinjiang, zimene akatswiri ena ofukula zinthu zakale akuganiza kuti n’zimene zinakhalako zaka 10,000, zimasonyeza alenje omwe amaoneka ngati maseŵera otsetsereka a m’madzi. Koma akatswiri ena ofukula zinthu zakale amatsutsa mfundoyi, ponena kuti zojambula za m’phanga sizingakhale zadeti lodalirika.
