Arheoloogide avastus P\u00f5hja-Keenias n\u00e4itab, et k\u00f5ige varasemad inimesed, kes elasid 2,75 miljonit aastat tagasi, valmistasid t\u00f6\u00f6riistu mitte juhuslikult, vaid j\u00e4rjepidevalt ja p\u00f5lvest p\u00f5lve edasi antud oskustega. Senise teadusliku arusaama j\u00e4rgi hakkasid inimesed t\u00f6\u00f6riistu tegema alles umbes 2,4\u20132,2 miljonit aastat tagasi ning seda ebaregulaarselt ja juhuslikult. Sellest kirjutab<\/a> BBC. Teadlased avastasid, et Namorotukonani leiukohas kasutati sama t\u00fc\u00fcpi kivit\u00f6\u00f6riistu \u2013 teravaid kraabitsaid ja haamreid \u2013 v\u00e4hemalt 300 000 aasta jooksul, mis viitab s\u00fcstemaatilisele teadmiste edasikandmisele.<\/p>\n

See leid seab kahtluse alla senise arvamuse, et varased t\u00f6\u00f6riistad olid ajutised ja unustati kiiresti. Uuringute juht professor David Braun r\u00f5hutab, et t\u00f6\u00f6riistade stabiilne kasutamine v\u00f5is alata palju varem, kui seni arvati, ning ei s\u00f5ltunud otseselt aju suurusest. T\u00f6\u00f6riistade valmistamine aitas neil varajastel inimestel ellu j\u00e4\u00e4da kliimamuutuste keskel, muutes mitte oma keha, vaid toitumisviise, n\u00e4iteks kasutades t\u00f6\u00f6riistu loomade l\u00f5ikamiseks ja taimede kaevamiseks. Arheoloogid leidsid ka t\u00f5endeid, et need t\u00f6\u00f6riistad olid valmistatud hoolikalt valitud kividest, mis n\u00e4itab oskuslikkust ja materjalitundmist.<\/p>\n

Teadlaste s\u00f5nul n\u00e4itab see leid, et isegi v\u00e4ikese ajumahuga varajased inimlased olid v\u00f5imelised keerukateks tehnoloogilisteks lahendusteks. Uuring pakub uut vaatenurka inimese evolutsioonile: v\u00f5ime kohaneda tehnoloogia abil ilmnes juba v\u00e4ga varakult. T\u00f6\u00f6riistade kasutamine v\u00f5imaldas neil s\u00e4ilitada elustiili ka siis, kui keskkond drastiliselt muutus, n\u00e4iteks rohumaade asendusid savanni ja poolk\u00f5rbega. See v\u00f5is olla murdepunkt, mis eristas inimesi teistest loomadest juba inimkonna koidikul.<\/p>\n
