Mukati memadzitateguru emunhu tine iyo homo ergaster. Ihominid yakaonekwa mukondinendi yeAfrica makore angangoita mamirioni maviri apfuura. Kubva zvakawanikwa zvisaririra zvevanhu ava, pave paine kusawirirana kukuru pakati penyanzvi. Vamwe vanofunga kuti mhuka iyi pamwe chete ne Homo erectus imhando imwechete, nepo dzimwe nyanzvi dzichiti idzo dzakasiyana.
Muchikamu chino tiri kuzokuudza zvese hunhu, mavambo uye zvido zve homo ergaster.
Mhando huru
Pfungwa iriko nhasi ndeyekuti mhando iyi yemunhu yaive yakazvarwa yakazvarwa iyo . Inofungidzirwa se hominid yekutanga inogona kusiya kondinendi ye Africa. Iyo anatomi iyo iyi mhando ine inomiririra shanduko yekusvetuka pamusoro pemamwe apfuura mhando. Nenzira iyi, tinoratidzira kureba kunogona kusvika kutenderera 1.8 metres. Sezvimwe nezvimwe zvipuka, iyi inomira zvakanyanya kunyanya kuve neakakura masimba. Aive nehunyanzvi uhwu kupfuura hwaive nemadzitateguru ake. Nechikonzero ichi, vanyori vazhinji vanofunga kuti kukwirisa nyama kudyiwa kunotsanangura kuwedzera kweiyi cranial kugona.
Yakashandurwa, homo ergaster zvinoreva murume anoshanda. Rudzi urwu rwakaunza nekuvandudzika kukuru mukujekeswa kwemidziyo uye midziyo yayo yakatanga kuve yakaoma. Nekuva nemhando iri nani yemidziyo iyi, zvaigoneka kufarira hunyanzvi hwekuvhima uye nezvimwe zviitiko zvekudyidzana.
Zvidzidzo zvakaitwa pane ino hominid zvinoreva kuti nyanzvi dzinogona zvakare kuzviona semutsivi we Homo habilis. Pane rimwe divi, vamwe vanyori havabvumirani zvizere neizvi uye hapana kuwirirana kwakazara. Kune vazhinji paleoanthropologists vanofunga kuti inogona kunge iri imwechete mhuka. Iyo yekutanga zvisaririra zvemazana akati wandei emadehenya echikadzi akaverengerwa kusvika angangoita mamirioni 1.75 emakore.
Chimwe chezvinhu zvakakosha zvakawanikwa ndecha 1984. Mapfupa emukomana ane makore gumi nerimwe ekuberekwa akafukunurwa ndokubvumidzwa kuongororwa kweatomu yake. Pakati pezvinhu zvinonyanya kumira paive nekukwirira kwake. Akanga akareba anenge 11 metres pakufa kwake, saka yaigona kusvika 1.8 mita. Simba rehenya iri raive rinosvika mazana masere masere masendimita masendimita uye muviri waro waive nemamiriro emapfupa ese akafanana neemunhu wazvino.
Kudanana uye nenzvimbo nzvimbo yeiyo homo ergaster
Hominid uyu akararama panguva iyo Middle Pleistocene epoch anenge makore 1.9 emakore apfuura. Idzo mari dzakawanikwa dzinoratidza kuti kwavo kwekugara kwaigara zuva nehupenyu hwaive muEthiopia, Tanzania, Kenya neEritrea. Munzvimbo yese iyi mamiriro ekunze aive akawoma uye kusanaya kwemvura kwakatora makore angangoita zviuru zana.
Dzimwe nyanzvi dzinobvuma kuti iyo homo ergaster yaive hominid yekutanga yaigona kusiya kondinendi ye Africa. Nekuda kwekutama uku, yaive yakakwanisa kuchinjika kune dzimwe nzvimbo dzepasi umo mune mamwe mamiriro ekunze, zvinomera nemhuka. Isati yasiya kondinendi yeAfrica, yakawedzera kuburikidza nenzvimbo yese iyi, ichisvetukira kuMiddle East Asia pakati pemakore angangoita 1.8 kusvika 1.4 emakore apfuura. Zvinozivikanwa kuti akauya kuzotora nzvimbo Caucasus. Zvimwe zvakasara zvakawanikwa muSpain neItaly kubva pamamiriyoni gumi nemana emakore apfuura.
Kune vazhinji nyanzvi dzesainzi vanosimbisa kuti yakakurumidza kupa nzira kune iyo Homo erectus sekutanga. Mamwe masayendisiti anoti iwo mamwe marudzi ayo anosiyana munzvimbo dzawo. Mumunda wemageneti tinowana kusiyana kwemajini zvichienderana nenzvimbo. Kana imwe mhando ichikura mune imwe nharaunda ingangoita yekuvandudza mamwe akasiyana mamishinari maitiro. Nekudaro, izvi hazvireve kuti mhando dzakasiyana, asi kuti inochinja nekuda kweimwe nhevedzano yekuchinja.
Hunhu hwepanyama hweiyo homo ergaster
Ngatione kuti ndeapi maitiro enyama ane munhu uyu. Dehenya rayo raive ne-supraorbital visor. Nzvimbo yetsiye yakanga iri diki zvakanyanya pane iya yemadzitateguru, kunyange hazvo yakati kurei kupfuura iya yemunhu wazvino. Huremu hwaisanganiswa hwaive pakati pe52 uye 68 kg uye ivo vakaputirwa zvakakwana. Makumbo ake akareba uye hapana humbowo hwekucherechedzwa kuita bonde. Izvi zvinotsanangura kuti pakange pasina mutsauko weatomiki pakati pevarume nevakadzi. Pakati pavo vaigona kuita anenge akafanana mabasa zvisinei nebonde.
Kuonekwa kwechiso kwakaratidzirwa nemhino yakanyanyisa kubuda uye shaya nemeno zvidiki pane izvo zve Homo habilis. Kukura kwouropi kwaisimudzirwa nokuchinja kwezvokudya, uye chipfuva chakarembera chakananga kumapfudzi, uku mapfupa echidya achirebesa.
Zvimwe zvinhu zvemuviri zvakaburitsa shanduko yakakosha munzira yekugadzirisa tembiricha yemukati. Uye ndezvekuti anogona kukura ziya uye zvakamuita kuti arasikirwe nevhudzi remuviri munguva yepakati nepakati. Musoro webvudzi wakaonekwa mumapapu akavandudzwa mberi. Izvo zvinofanirwa kutariswa kuti uyu munhu anga achiwedzera kutonga kuita zviitiko zvakaomarara, saka zvaida simba rakawanda uye oxygenation kuti zvikwanise kuzviita.
Kufema kwakamira kuve kungotaura chete uye kwakatangawo kufema nemumhino. Aya ndiwo maitiro avakakwanisa kurarama munzvimbo yakavhurika savanna uko kuwedzera kufamba kwaive kwakakosha kuitira kuti vatize zvikara uye kuvhima mhuka yavo.
Maitiro
Nyanzvi zhinji dzinoti pakati pemafambiro e homo ergaster hapasisina kushandisa miti kuitira kufamba. Iyi ndiyo nzira yaakakwanisa kusiya zvachose chimiro che arboreal yevakawanda vemadzitateguru ake uye kurarama chete pasi. Iwo akanyanya stylized hominids uye anatomy yavo yakachinjika kune nharaunda yavaigara. Kugara muSavanna kwakanga kusinganyanyi kushanda zvakanaka kubva pamiti. Vakafamba nenzira yakafanana nevanhu vemazuva ano.
Kana isu tikaenda kune yemagariro chimiro, ivo vakasimbisa hukama hwakaoma munharaunda. Mutauro wekutaura wakaonekwa kunyangwe asiri ese masayendisiti anobvumirana neizvi.
Ndinovimba kuti neruzivo urwu iwe unogona kuziva zvakawanda nezve iyo homo ergaster uye hunhu hwavo.
