Ekuguqukeni komuntu njengoba sazi namuhla, kube nezinhlobo eziningi. Enye yazo yi- U-Homo u-antecessor. Iwuhlobo lwezinhlobo zezinto eziphilayo manje esezingasekho kodwa ziyingxenye yohlobo lweHomo futhi lubhekwa njengenye yezokuqala nezindala ezake zahlala eYurophu. Ngokwezinsalela ezitholakele zalo muntu, kwakwaziwa ukuthi wayekhona cishe eminyakeni eyizi-900.000 edlule.
Kulesi sihloko sizokutshela zonke izici, imvelaphi nokuvela kwe U-Homo u-antecessor.
Izici eziyinhloko
Kuyinhlobo engeyomuntu nokuthi ulayini wokuziphendukela kwemvelo uphakathi kwe- UHomo heidelbergensis futhi i I-Homo neanderthalensis. Kwakuyi-hominid yokuqala ehlala eYurophu futhi idabuka e-Afrika. Cishe bonke ososayensi bakholelwa ukuthi yisizinda sesintu nokuthi ukufuduka kwenzeka kanye kanye ukuya eYurophu nase-Asia. Kulinganiselwa ukuthi endabeni yesikhathi sokwakheka komhlaba yaphila ngesikhathi I-Pleistocene phansi. Ezinye zezici lolu hlobo lwazo olunazo zasendulo kanti ezinye zesimanjemanje. Lokhu kunquma ukuthi ukuxubana kokuziphendukela kwemvelo koshintsho ekuguqukeni komuntu.
Izindawo zokuqala zalezi zinsalela kwakuyilezo ezitholakala edolobheni laseCeprano e-Italy, okwenza kube indawo efanele emlandweni we U-Homo u-antecessor. Kusukela ngaleso sikhathi kwaduma ngaphansi kwegama elivamile elithi Ceprano man. Ingxenye eyinhloko yezinsalela ezifundwe ngokujula okukhulu ugebhezi olunezici ezisukela kokwakudala kuye kwesimanje. Obunye ubufakazi besayensi obulinganisa iminyaka yalolugebhezi ukuthi ibhalwe cishe iminyaka engama-900.000 ubudala. Njengoba inezici ezahlukahlukene ze-phylogenetic, chronological and archaeological ezifanayo nalezo zezinye izinhlobo, yabizwa ngegama lomhloli wamazwe noma iphayona.
Izinsalela ezigcinwe ezimeni ezingcono umhlathi ongaphezulu kanye nethambo elingaphambili lomuntu osemusha okuphila kwakhe sekushonile kulinganiselwa ukuthi kwenzeka cishe eminyakeni eyi-11. Endaweni efanayo lapho lezi zinsalela zazitholakala khona, kwakunezingcezu ezimbalwa zamathuluzi amatshe namathambo ezilwane amaningi. Lokhu kukhombisa ukuthi lo muntu usengakwazi ukwakha amathuluzi, njengoba kubhaliwe kwezinye ama-hominids.
Nakuba wonke lamathambo nezinsalela kwaziwa ukuthi kudala emuva cishe eminyakeni eyisigidi, ukuqhathanisa okuqondile kunzima ukwenza. Futhi ingxenye ngayinye yomzimba kanye nokwakheka kwayo kuhambisana nabantu abahlukene beminyaka yobudala ehlukene.
Ukunwetshwa kwe-Hominid kanye ne U-Homo u-antecessor
Okungaqinisekiswa ukuthi izinsalela zinezici ezithile ezihlukile ezifanayo. Futhi cishe zonke Bavela kubahlali bakudala ababehlala e-Afrika kanti abanye asebevele bathuthele eYurophu. Phakathi kwezici zomzimba nezebhayoloji zalolu hlobo sithola inhlanganisela yogebhezi kanye namazinyo kanye nomhlathi ongezansi oluhlukanisayo kwezinye izinsalela zohlobo lweHomo. Ezinye izinsalela zifana nezabantu besimanje kodwa zinokwakheka okuthe ukuqina. Ukuphakama ngokwesilinganiso phakathi kwamamitha ayi-1.6-1.8 okungadluli okwamanje Homo sapiens. Isisindo salaba bantu sasilingana cishe phakathi kwama-65 no-90 kilos, ngakho-ke icishe ifane nalena yamanje.
Ugebhezi lunezinhlanganisela ezithile nezici zesimanje kanye nezakudala. Phakathi kwezici zesimanje kukhona i-canine fossa, ama-cheekbones angenalutho kanye nekhala eliphumayo. Lezi zingxenye ziyinikeza ukubukeka okunesitayela okuthe xaxa kunezinye izinhlobo ezindala. Ngakolunye uhlangothi, uma sihlaziya izici ezindala sibona ukuthi unesiphongo esingezansi kanye ne-ridge yasebunzini ephawulwe kabili. I-occipital vault yayo nayo igqame kakhulu, ikakhulukazi ngemuva kogebhezi.
Ngokuqondene nosayizi wobuchopho, buba buncane kunomuntu wamanje. Yize kungewona umehluko omkhulu, ubunomthamo ophansi ngaphezudlwana kwesilinganiso samanje. Izici zamazinyo zakudala zigqama ngokuba namazinyo aqinile kanye nama-premolars anezimpande eziningi ze-incisor ezisebenzela ukugaya ukudla kangcono. Izici ezibhekwa njengezanamuhla maqondana nomlomo zihlobene nama-canines. Futhi, amanye amazinyo angaphambili angahlukaniswa ngoba ziyabonakala ngosayizi omncane uma kuqhathaniswa nezinye izinhlobo ze-hominid.
Kuye kwatholakala ukuthi amaphethini okuqhuma kwamazinyo afana nalawo abantu banamuhla, ngakho-ke kungaphethwa ngokuthi lawa ma-hominids anezinga lokukhula elifana nalawo avela kamuva emlandweni wokuziphendukela kwemvelo komuntu.
Ukufana phakathi kwe- U-Homo u-antecessor futhi i Homo sapiens
Sizohlaziya ukuthi yiziphi izici eziyinhloko ezifanayo kuzo zombili izinhlobo. Ngalokhu, kufanele sicabangele inani eliphelele labantu abakulesi sakhi. Yena U-Homo u-antecessor Ingenye yezinhlobo ezinokufana okufana kakhulu nomuntu wamanje. Into yokuqala okufanele siyicabangele ukuqhathanisa ukukhula kwayo. Luhlobo lokukhula olufana nolwethu. Isigaba sobuntwana nesobusha sidlula ngokunensa kunasesimweni sezinye izinhlobo. Ngohlobo lwethu Sinesikhathi sokukhula ngaphambi kokuba siqhathanise ngokulingana nesikhathi sokuphila okuphelele.
Izici zalolu hlobo zingaba ukuxubana phakathi kwezakudala nezanamuhla. Kunemininingwane ethakazelisa ngokwengeziwe maqondana nalezi zinhlobo nokuthi lokho kwakuthathwa njengesibonelo esihle kakhulu. Ngaphambi kwalezi zinhlobo ezithile, amanye ama-hominids ayethandana noma okungenani ayengenawo umkhuba ophawulekile wokusebenzisa elinye lamalungu ngokuqinile.
Esinye isici esingaqhathanisa nesibaluleke ngokweqile amashiya nebunzi. Uma siqhathanisa amashiya nebunzi le- U-Homo u-antecessor nalokhu komuntu wamanje siyabona ukuthi bekufana kakhulu. Kodwa-ke, lezi zimfanelo zingatholakala nakwezinye izinhlobo eziguquke kakhulu ezivela egatsheni elihlukile lokuziphendukela kwemvelo.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi nge U-Homo u-antecessor kanye nezici zabo.
