Imisebenzi yomntu osekudala

Iimbopheleleko zabasebenzi zihlala zidlala indima ebalulekileyo ekuguquleni koluntu kwaye ngezinye iindlela ziye zasebenza njengomlinganiselo wokuphuhliswa kwayo. Akusiyo into yokuba iinkcubeko nezenkcubeko zidibaniswa kwaye zithiwa ngokwemiqathango apho umntu edale khona isixhobo somsebenzi. Ngoko, iikhosi zenkcubeko zibizwa ngolu hlobo lulandelayo: ubudala bamatye, ubudala bebhedu kunye nobudala bentsimbi. Ngethuba lokuphuhliswa kwalo, uluntu luye lwahamba phambili xa lufumanisa ukuba ilitye linokubanceda kakhulu ubomi kunye nokuzingela.

Izixhobo zokuqala: imvelaphi kunye nezinto eziphathekayo

Ixesha eliphambili lokuphuhliswa koluntu libizwa ngokuba ngumda wamatye, kuba ngelo xesha abantu babengakwazi ukubhala kwakhona, kodwa babekwazi ukudala izixhobo zokunyusa kwabo, kwaye ekupheleni kweli xesha babekwazi ukuhlalisa izilwanyana.

Izixhobo zokuqala zabasebenzi zenziwe ngamatye, kodwa ngamanye amaxesha kwakusetyenziselwa izitya, amathambo kunye nodongwe. Ukongezwa kwezixhobo kwenziwa ngokuthe ngcembe, ngoko akunakutsholwa ukuba zonke ezi zinto zaqala ukusetyenziswa ngobusuku.

Izixhobo zamatye zokusika zenziwe nge-silicon kunye ne-calestone shales. I-Basalt kunye neentsika zazisetyenziselwa njengezixhobo zokusebenza (umzekelo, isigxina sesandla).

Ukubala kwesi sihlandlo kwaqala xa enye ihominid icinga ukuba ithathe ilitye kwaye iyisebenzise ngenjongo yasekhaya, eyenzeka malunga ne-3 yezigidi zeminyaka edlulileyo. Ukusuka kuloo mzuzu ukujika kwimiba emitsha kwimbali kunye nokuguqulwa komntu kwizinto ezikhoyo ngoku. I-hominid yafunda ukusetyenziswa kwelitye ngeenjongo zayo, ukuphucula ubuchwephesha apho kwi-19 leminyaka ubudala beelitye behlelwa ngamaxesha ama-2: i-Neolithic ne-Paleolithic, kwaye okokugqibela, kwahlulwa ngamaxesha amaninzi.

Indlela yokuqala yokusebenza: iteknoloji

Ukufumana i-flake yesiqhelo (obunqamlekileyo, ngomgca ogqamile we-cached), kwakudingeka ukuba uthathe uluhlu lwezenzo ezilandelelanayo: ukufumana ilitye elifanelekileyo, indawo kuyo, ukuba uyayifaka kwinqanaba elithile kwaye ubale amandla, uza kufumana isixhobo sohlobo oluyimfuneko. Lo msebenzi unzima kunzima, kwaye kunzima nakakhulu ukuba iimfuno ezimiselweyo kwifom. Kwizinto zokuvubukulwa kukho into enje njengokubuyiswa kwezinto: ithetha inkqubo yokuhlutha okuncinci, eyasetyenziswa ngabantu bamandulo.

Ukulawula ubuchwephesha, inkcazo ehambelana nezivakalisi ezimbalwa, ithatha ixesha elide kakhulu kubantu basendulo, kwaye ukuphuculwa kwayo kwenzeka kwirejista enye.

Iimpawu zabasebenzi ezisuka kwithambo

Ngexesha elide le-Paleolithic (malunga neminyaka eyi-45 ukuya kweyamawaka edlulileyo) indoda yoluhlobo lwangoku ivela, kodwa ininzi yezinzulu zithethwa ukuba yabonakala kwangaphambili, malunga namawaka amawaka amabini edlulileyo. Eli xesha lidibaniswa nokuqaliswa kokusetyenziswa kwezixhobo ezisuka kwithambo, izibonda kunye neepondo. Njengoko kwavela, bahamba ngaphezu kweeplastiki ngaphezu kwelitye, kwaye ngexesha elinye liqina ngakumbi kuneenkuni, kwaye ngoko ke kulula. Kwaye kwaba ngokokufumanisa okwenene kunye ne-harbinger yeenguqu ebomini babantu abafunde ukwenza imidya, imikhonto, imimese emide (eyayilula kwaye ilula ngakumbi kunamatye).

Indlela yokusebenza emathanjeni yenza kube lula ukuba abantu basuse izikhumba kwizilwanyana ezibuleweyo, kuba kuye kwaba lula ukwenza izixhobo ezifanelekileyo kunye neenaliti ezincinci, ezithi, ngokutsho kwezinto zakudala, zingaphantsi kobunzima kunye nobukhali kwizinyithi zanamhla. Abantu bafunda indlela yokugqoka iimpahla kwiibhokhwe, endaweni yezingcingo ezisetyenzisiweyo.

Ukususela kwimigodi kunye neempondo zenza izixhobo ezikhethekileyo zokumba ama-digg and pitry pits. Kuyathakazelisa ukuba ngeli xesha abantu babengekhona kuphela izinto ezinokwenziwa komsebenzi, kodwa kunye neendwanguzo, ezenziwe ngethambo.

Ukusetyenziswa kwezixhobo kwithambo

Ukuze kuveliswe imveliso efunekayo kwiphondo oluqhelekileyo, ngamanye amaxesha abantu basebenzisa inqobo efanayo njengelitye: basusa amaqabunga kwaye batyhulwa, kwaye ke into efunekayo yenziwe kwinqande.

Nangona kunjalo, ubuchwepheshe obutsha besetyenziswe rhoqo: ukusika, ukusika nokucoca. Abantu abazange bayeke kwizinto eziye zaphunyezwa kwaye zafezekisa izinto zokusebenza, ziphosa ukuba zikhanye.

Ngeli thuba, kukho into ebonakalayo yaba ngumqondiso wentuthuko ebalulekileyo - i-silicon scraper equkethe izinto ezahlukeneyo: ilitye kunye nomthi okanye ilitye kunye nethambo. Ukudibanisa kwakuhlukile, kodwa oko kwakuthetha ukuba le ndoda yayifunde ukudala izinto ezamnceda ukuba aphile kwaye abonise amandla aphilileyo okuphila, kwaye ekugqibeleni kukhokelela ekuveleni kwempucuko yethu.
