Ib pab pawg ntawm cov kws tshawb fawb koom nrog ntau lub tsev haujlwm hauv Spain, ua haujlwm nrog ob tus npoj yaig los ntawm Fabkis thiab lwm tus los ntawm lub teb chaws Yelemees tau tshawb pom Obsidian handaxe-kev cob qhia los ntawm 1.2 lab xyoo dhau los hauv Awash hav hauv Ethiopia. Nyob rau hauv lawv daim ntawv luam tawm nyob rau hauv phau ntawv journal Nature Ecology & Evolution, pab pawg piav txog qhov twg cov handaxes tau pom, lawv tus mob thiab lawv hnub nyoog.
Lub Hnub Nyoog Pob Zeb tau kav los ntawm kwv yees li 2.6 lab xyoo dhau los, mus txog kwv yees li 3,300 BCE, thaum lub hnub nyoog Bronze pib. Cov keeb kwm feem ntau rhuav tshem lub sijhawm mus rau Paleolithic, Mesolithic thiab Neolithic lub sijhawm. Kev tshawb fawb ua ntej tau pom tias "kev cob qhia kev cob qhia" tshwm sim qee lub sijhawm thaum nruab nrab Pleistocene, hauv Tebchaws Europe - kwv yees li 774,000 txog 129,000 xyoo dhau los.
Cov kev cob qhia zoo li no tau tsim los ua cov cuab yeej ua tau hloov mus rau hauv kev txawj. Cov tib neeg uas tsim cov txuj ci zoo li no tau ua haujlwm ua ke hauv kev cob qhia kom ua kom txaus ntawm txhua yam cuab yeej xav tau los ntawm cov neeg nyob hauv cheeb tsam. Ib qho cuab yeej zoo li no yog handaxe, uas tuaj yeem siv rau chopping lossis ua riam phom.
Handaxes tau tsim los ntawm chipping cov khoom tawm ntawm lub pob zeb kom ua kom ntse ntug. Lawv tsis txuas nrog dab tsi; lawv tsuas yog tuav hauv tes thaum siv. Cov pob zeb siv feem ntau yog flint lossis, nyob rau hauv lub sijhawm kawg, obsidian - ib hom volcanic iav. Obsidian, txawm nyob rau lub sijhawm niaj hnub no, suav tias yog cov khoom siv nyuaj ua haujlwm nrog vim tias nws yog qhov ntxhib ntawm tes. Hauv qhov kev siv zog tshiab no, cov kws tshawb fawb tau pom cov pov thawj ntawm obsidian handaxe knapping Rhiav tau tsim ua ntej tshaj li qhov tau pom ua ntej.
Cov kws tshawb fawb tau ua haujlwm ntawm Melka Kunture khawb qhov chaw thaum lawv pom ib lub handaxe faus rau hauv ib txheej ntawm sediment. Lawv nrhiav tau sai sai no. Lawv pom 578 nyob rau hauv tag nrho, thiab tag nrho tab sis peb tau ua los ntawm obsidian. Kev sib tham ntawm cov khoom nyob ib ncig ntawm lub axes tau qhia lawv los ntawm kwv yees li 1.2 lab xyoo dhau los.
Txoj kev tshawb fawb ntawm cov axes tau pom tias lawv txhua tus tau ua haujlwm zoo ib yam, qhia tias cov kws tshawb fawb tau pom ib qho kev cob qhia qub qub. Qhov kev nrhiav pom yog qhov piv txwv qub tshaj plaws ntawm qhov kev cob qhia, thiab thawj qhov tsis yog nyob hauv Europe. Cov kws tshawb fawb tau sau tseg tias txoj haujlwm tau ua tiav ntev dhau los uas lawv tseem tsis tuaj yeem txheeb xyuas cov hominids uas ua rau lawv.
Txoj kev tshawb fawb tau luam tawm nyob rau hauv phau ntawv journal Nature Ecology & Evolution (2023). Nyeem qhov thawj tsab xov xwm.
