Izigaba Evolution Human

kwemvelo yabantu abantu basoloko abanomdla. Aye aba ngeenxa amashumi okanye amakhulu eminyaka ukufunda thiyori ngemvelaphi yobomi on Earth. Benze nayo iqashiso. Inguqulelo kakhulu ethandwa nguye sichaza imvelaphi ngabantu abasuka iinkawu kunye nezigaba kwembali yabantu.

Kodwa kwakukho iimbono ezimbini kumaxesha amandulo kulo mba. Ithiyori lokuqala kuthiwa abiogenesis. Yena uthi kukho ithuba lokuphila ezintweni. Enye ingcamango kuthetha nakwenzeka ngemvelaphi ezimeleyo yobomi. Kukho nezinye iindlela; umzekelo, ukudalwa eziphilayo emhlabeni nguThixo. Makhe siqwalasele ngakumbi ngokucokisekileyo amanqanaba asisiseko kwembali yabantu.

Umntu kudala wazama ukuba baphonononge nomnombo wabo. Oku kubonakala amavo, amabali, epics phantse zonke iintlanga nezizwe.

Kuphela ngo 1859 wapapasha incwadi ka Charles Darwin, echaza imvelaphi lweentlobo ngenxa ukhetho zendalo. Wabangela a ukuzwa kwaye yavus 'umdla omkhulu. Abaninzi bagxeka ingcamango yakhe, bagxeka yaye egculelwa. Kodwa abantu abasondeleyo kwinzululwazi, bayinqule le ndalo.

Le ncwadi ichaza imvelaphi yendalo yomntu. Kukho kwakhona kubangela kunye nobungqina, olusekelwe kulwazi lwenzululwazi. Babethetha ngolwalamano womntu kunye ezincancisayo kwinqanaba yemfuza. Ekuhambeni kwexesha, Darwin wabonakala kubalandeli abaqala ukufunda amanqanaba kwemvelo.

Man kwaye ezinye ezinomqolo ezineefitsha eziqhelekileyo zesakhiwo. Umzekelo, iimpawu ze-nervous system, skeletal, yokwetyisa, bokuphefumla kwegazi. Oku kubonakala kakhulu ngokucacileyo xa ucinga ukuba ubudlelwane Palsy.

iimpawu ezithile zakuqala kunye atavism. Zikhona emzimbeni kukuninzi, kodwa ngamampunge. Eli lifa okusele yookhokho zezilwanyana. Ukuba sicinga umntu ngokwemiqathango eziphilayo, kuba sisilwanyana esincancisayo le suborder eliphezulu enxulumene obeku-. Noko ke, abantu - ukuba nengqiqo. Ukufana omkhulu kunokubonwa abantu iinkawu, umahluko phakathi kwabo kukukwazi ukusebenza nokusebenzisa izixhobo.

Amanqanaba kwembali yabantu ziquka ixesha xa kwakukho zivunywa abantu ekwaziyo imisebenzi usebenzisa imipu. Ngaphezu koko, kwabakho inguqu ukusuka isicelo ezivelisa izinto yabasebenzi. Yaba zivunywa ukuba kwenzeka ngenxa yokuba izinto zazivelela. Ukutya ukutya okulungiselelwe ukusetyenziswa komlilo, ukunciphisa umthwalo kwinkqubo yokwetyisa. Ngokuthe ngcembe, ukuba unenzondelelo utshintsho (i emathunjini elifutshane).

Kukho izigaba ezithathu kwembali yabantu.

1. ukuvela kwe-Homo sodidi, owokuqala lowo Australopithecus. Eli nqanaba ye revolution eziphilayo.

2. Oku kulandelwa kwisigaba esilandelayo kwi nasekusungulweni kwale kuzenza. Buhlala phambi ekuqaleni kweqonga mihla kwembali yabantu. Apha, le nkqubo waba nefuthe zinto nje eziphilayo, kodwa lwentlalo. Phakathi abameli eli thuba ziyakwazi ukuchongeka Pithecanthropus, abantu eHeidelberg Sinanthropus kunye Bamandulo Phaya.

3. Inqanaba lokugqibela ithathwa nasekusungulweni ngabantu mihla. Apha, i ezichaphazeleke imiba yezentlalo yobukho.

Lichaza zokuqala ezenziwa ngabantu kunye nokusetyenziswa izixhobo ezifumaneka kwisithuba 2.5 -. Kwiminyaka yezigidi 2.8 eyadlulayo. Kwakhona eyaziwayo ukuba abantu abaninzi zabantu ngokuthi kufakwe omnye komnye nje bazivelela. Belikhona ngexesha elifanayo wanyamalala ngenxa lomzabalazo lokusinda.

Man - oku sisidalwa esifanelekileyo omabini iimpawu zebhayoloji nezentlalo. Oku iyayahlula naye kwezinye izidalwa eziphilayo emhlabeni.
