Kev soj ntsuam ntawm ob-taw ntoo ntuav pov tseg, nrhiav pom hauv Schöningen, Lub Tebchaws Yelemees 30 xyoo dhau los, tau qhia tias nws tau raug khawb, seasoned, thiab sanded ua ntej yuav siv rau tua tsiaj. Qhov kev tshawb fawb no tau ua pov thawj tias tib neeg thaum ntxov muaj cov txheej txheem kev ua haujlwm ntoo ntau dua li qhov kev ntseeg ua ntej.
Kev tshawb fawb qhia tias muaj peev xwm tsim cov riam phom sib sib zog nqus tau ua rau kev yos hav zoov ntawm cov tsiaj nruab nrab thiab me me raws li pab pawg ua haujlwm. Kev siv pov tseg los ua ib qho cuab yeej rau kev yos hav zoov tuaj yeem yog ib qho kev tshwm sim hauv zej zog, suav nrog cov menyuam yaus.
Kev tshawb fawb tau ua los ntawm Dr. Annemieke Milks los ntawm University of Reading's Department of Archaeology. Raws li nws, kev tshwm sim ntawm cov cuab yeej ntoo tau hloov pauv peb txoj kev xav ntawm tib neeg kev ua thaum ub. Nws yog qhov zoo tshaj plaws uas cov tib neeg thaum ntxov no muaj kev pom zoo thiab kev txawj ntse nrog ntoo, txawm tias siv ntau yam kev ua haujlwm ntoo uas tseem ua haujlwm nyob rau niaj hnub no.
Lub peev xwm rau tag nrho cov zej zog koom nrog kev yos hav zoov tuaj yeem tau nce los ntawm cov khoom siv pov tseg no, ua kom tswj tau ntau dua li hmuv hnyav dua. Qhov no tuaj yeem tso cai rau cov menyuam yaus xyaum pov thiab tua tsiaj nrog lawv.
Dirk Leder, ib tus kws sau ntawv, tau sau tseg tias tib neeg Schöningen tau tsim cov cuab yeej ergonomic thiab aerodynamic los ntawm ceg ntoo. Yuav kom ua tiav qhov no, lawv yuav tsum tau txiav thiab txiav cov tawv ntoo, ua kom nws zoo, khawb ib txheej, lub caij nplooj ntoo kom tsis txhob tawg lossis tawg thiab xuab zeb kom yooj yim tuav.
Xyoo 1994, ib lub pas 77cm-ntev tau pom nyob rau hauv Schöningen, nrog rau lwm yam cuab yeej xws li pov hmuv, thrusting hmuv, thiab ib qho ntxiv ntuav uas zoo sib xws.
Nyob rau hauv ib txoj kev tshawb no tshiab, ib tug ob-taw pov pov stick yog tshuaj xyuas nyob rau hauv ib tug heev meej meej. Cov cuab yeej no tau ua haujlwm rau tib neeg thaum ntxov hauv kev tua tsiaj nruab nrab, xws li liab thiab roe mos lwj, nrog rau cov tsiaj me me, nrog rau hare thiab noog, uas nyuaj rau ntes.
Cov tib neeg thaum ntxov tuaj yeem tuaj yeem cuam tshuam nrog kev sib hloov, zoo li boomerang, nyob deb li ntawm 30 meters. Txawm hais tias cov khoom no yog qhov hnyav, lawv tseem tuaj yeem tsim muaj kev cuam tshuam loj heev vim qhov nrawm nrawm uas lawv tuaj yeem tsim tawm.
Cov ntsiab lus zoo nkauj thiab polished sab nrauv, nrog rau cov cim ntawm kev hnav, txhua qhov taw qhia rau daim ntawv no tau siv ntau zaus, tsis maj nrawm tsim thiab tom qab ntawd tsis nco qab.
Thomas Terberger, tus thawj coj tshawb fawb, tau hais tias German Research Foundation-nyiaj pab kev ntsuas kev ntsuas ntawm Schöningen ntoo artifacts tau txais txiaj ntsig kev paub tshiab thiab cov ntaub ntawv txhawb nqa ntau ntxiv txog cov cuab yeej ntoo qub tau xav tias yuav sai sai no.
Txoj kev tshawb fawb tau luam tawm nyob rau hauv phau ntawv journal PLOS IB nyob rau lub Xya hli ntuj 19, 2023.
