Ngokocwaningo olusekelwe ezithombeni zomlando, amathambo kungenzeka ukuthi agcinwe izinkulungwane zeminyaka ngaphambi kwezidumbu ezaziwa kakhulu.
Ngokocwaningo olusha, iqembu lezidumbu zabantu ezineminyaka engu-8,000 ubudala ezitholwe eSado Valley ePortugal zingase zibe izidumbu ezindala kunazo zonke ezaziwayo emhlabeni.
Abacwaningi bakwazile ukuphinda benze izindawo zokungcwaba okungenzeka zisekelwe ezithombeni ezithathwe ezinsalela ezingu-13 lapho zimbiwa ekuqaleni kwawo-1960, ziveza ulwazi ngemikhuba yomngcwabo eyayisetshenziswa abantu base-European Mesolithic.
Lolu cwaningo, olwanyatheliswa kuyi-European Journal of Archaeology yithimba lase-Uppsala University, i-Linnaeus University, kanye ne-University of Lisbon ePortugal, luveza ukuthi abantu baseSado Valley babeshisa izidumbu ngokucwilisa izidumbu.
Ngaphakathi, izicubu ezithambile emizimbeni azisalondoloziwe, okwenza ukufuna izimpawu zokulondolozwa okunjalo kube inselele. Ochwepheshe basebenzise indlela ebizwa nge-archaeothanatology ukuze babhale futhi bahlaziye izinsalela, baphinde babheka imiphumela yokuhlolwa kokubola okwenziwa yi-Forensic Anthropology Research Facility yaseTexas State University.
Ngokusekelwe kulokho esikwaziyo ngokuthi umzimba ubola kanjani, kanye nokubhekwa mayelana nokusatshalaliswa kwendawo yamathambo, abavubukuli benza izimali ezidonswayo mayelana nendlela abantu baseSado Valley ababezisingatha ngayo izidumbu zabo, abazingcwaba beguqe futhi becindezelwa. ngokumelene nesifuba.
Njengoba imizimba iqala ukuwohloka kancane kancane, kubonakala sengathi abantu abaphilayo baqinisa izintambo ezibopha amalungu endaweni, bezicindezela endaweni ababeyifisa.
Uma izidumbu bezingcwatshwa zisesimweni esinqunyiwe, kunokuba zibe izidumbu ezintsha, lokho bekungachaza ezinye zezimpawu zezinqubo zokucwiliswa kwezidumbu.
Akukho ukungezwani ongayilindela emalungeni, futhi imizimba ikhombisa i-hyperflexion ezithweni. Indlela inzika eqoqana ngayo emathanjeni yagcina ukuzwakala kwamalunga futhi ibonisa nokuthi inyama ayizange ibole ngemva kokungcwatshwa.
Abantu baseSado Valley kungenzeka ukuthi banqume ukucwilisa abashonile ukuze kube lula ukuyiswa ethuneni futhi basize isidumbu ukugcina isimo saso empilweni ngemva kokungcwatshwa.
Uma izindlela zaseYurophu zokucwilisa izidumbu zibuyela emuva ezinkulungwaneni zeminyaka ngaphezu kwalokho okwakucatshangwa ngaphambili, kungasisiza siqonde kangcono izinhlelo zenkolelo ye-Mesolithic, ikakhulukazi lezo eziphathelene nokufa nokungcwatshwa.
Iningi lezidumbu ezisele emhlabeni azikho ngaphezu kweminyaka engu-4,000 ubudala, kuyilapho ubufakazi bubonisa ukuthi abaseGibhithe lasendulo baqala lolu hlelo eminyakeni engu-5,700 edlule.
Izidumbu zezidumbu zezidumbu zaseChinchorro zasogwini lwaseChile, okucatshangwa ukuthi yizidumbu ezindala kunazo zonke emhlabeni, zalondolozwa ngamabomu eminyakeni engaba ngu-7,000 edlule ngabazingeli abaqoqi besifunda.
