Dzidziso yekushanduka-shanduka kwevanhu maererano neAnthropology
Kushanduka-shanduka kwevanhu ibazi rakakosha rekudzidza mukati meanthropology, chidzidzo chinoongorora vanhu nezvinhu zvehupenyu hwavo munhoroondo yese. Muchinyorwa chino, tichanyatsoongorora dzidziso yekushanduka-shanduka kwevanhu kubva pamaonero evanhu, kuti yakatanga sei, uye humbowo hunotsigira iyi fungidziro.
Nhanganyaya: Kunzwisisa Kwekutanga Dzidziso yeKushanduka-shanduka
Dzidziso yekushanduka-shanduka idzidziso yesainzi inoratidza kuti zvipenyu zvese panyika zvakashanduka kubva kutateguru mumwe chete kuburikidza nemaitiro ekusarudza kwechisikigo kwenguva yakareba. Pfungwa iyi yakatanga naCharles Darwin mubhuku rake rinonzi "On the Origin of Species," rakaburitswa muna 1859. Zvisinei, patinotaura nezvekushanduka-shanduka kwevanhu, tiri kutaura nezverwendo rurefu rwakatitora kubva kumadzitateguru edu emhuka kuenda kuHomo sapiens yemazuva ano.
Mavambo Evanhu: Kubva kuPrimate kusvika kuHominid
Chimwe chinhu chikuru chedzidziso yekushanduka-shanduka kwevanhu ndechekunzwisisa kuti vanhu vane tateguru mumwe chete nemamwe mhuka dzerudzi rwechimpanzee nemagorira. Makore angangoita mamiriyoni manomwe apfuura, madzinza evanhu neechimpanzee akasiyana kubva kune tateguru mumwe chete anozivikanwa semahominid.
Nyanzvi dzezvevanhu dzinotenda kuti kushanduka-shanduka kwevanhu kwakatanga nekubuda kwemhando yemhuka inonzi Australopithecus, yaigara muAfrica makore angangoita mamiriyoni mana apfuura. Australopithecus afarensis ndeimwe yemhando dzinozivikanwa zvikuru dzeboka iri, uye chisaririra chayo chakakurumbira ndi "Lucy," chakawanikwa muna 1974. Lucy akaratidza kuchinja kwakakosha kune bipedalism, iyo inoonekwa sedanho rakakosha mukushanduka-shanduka kwevanhu.
Kukura kweHomo: Kubva kuHomo habilis kusvika kuHomo sapiens
Mushure meAustralopithecus, shanduko yakaramba ichienderera mberi murudzi rweHomo, rwakaratidza kuwedzera kukuru muhukuru hwehuropi uye kushandiswa kwezvishandiso. Rudzi rwekutanga murudzi urwu rwaive Homo habilis, iyo yakagara makore angangoita mamiriyoni 2,4 kusvika 1,4 apfuura uye inozivikanwa se "mhizha." Homo habilis yakaratidza kushandiswa kwezvishandiso zvematombo zviri nyore, zvichiratidza hunyanzvi hwepamusoro hwekuziva nemaoko kupfuura madzitateguru ayo.
Tevere, Homo erectus yakaonekwa makore angangoita mamiriyoni 1,9 apfuura uye ndiyo yaive mhando yekutanga inozivikanwa yeHomo kubva muAfrica ndokupararira muAsia neEurope. Homo erectus inoratidza humbowo hwakawanda hwekuchinja kwakafanana nekwevanhu vemazuva ano, kusanganisira kushandiswa kwakaoma kwezvishandiso uye humbowo hwekushandiswa kwemoto. Mafossil anozivikanwa eHomo erectus, kusanganisira "Turkana Boy" akawanikwa muKenya, anopa ruzivo rwakakosha pamusoro pemaumbirwo uye kuchinja kwemhando iyi.
Chimwe chezvinhu zvakakosha mukushanduka-shanduka kwevanhu kwaive kubuda kweHomo neanderthalensis (Neanderthals), avo vaigara kuEurope nekumadokero kweAsia. MaNeanderthals akaratidza kuchinjika kunoshamisa kune mamiriro ekunze anotonhora uye aive netsika dzakaoma dzaisanganisira kugadzira maturusi, hunyanzvi, uye pamwe mutauro. Kunyangwe maHomo neanderthalensis akatsakatika makore angangoita 40.000 apfuura, zvidzidzo zvemajini zvinoratidza kuti aive neDNA yakafanana neHomo sapiens, zvichiratidza kudyidzana uye kuberekana pakati pemarudzi maviri aya.
Homo sapiens: Vanhu vemazuva ano
Homo sapiens, rudzi rwevanhu vemazuva ano, rwakabuda muAfrica makore angangoita 300.000 apfuura. Zvisaririra zveHomo sapiens, zvakaita sezviri kuMorocco, zvinoratidza hunhu hwemuviri uye kugona kwepfungwa kwakafanana nekwevanhu vemazuva ano. Kukura kwevanhu vemazuva ano kunoratidzwa nekukwanisa kutaurirana kuburikidza nemutauro wakaoma, hunyanzvi, tsika, uye kukura kwehunyanzvi nekukurumidza.
Panguva iyi, Homo sapiens dzakatanga kupararira pasi rose uye dzakatsiva kana kusangana nedzimwe hominid dzakadai seNeanderthals neDenisovans. Humbowo hwemajini hunoratidza kuti vanhu vemazuva ano vane huwandu hushoma hweDNA kubva kumarudzi ese ari maviri, zvichiratidza kuti dzinoberekana panguva iyi yekutanga kutama.
Uchapupu hweKushanduka-shanduka kwevanhu
Humbowo hwekushanduka-shanduka kwevanhu hunobva muzvikamu zvakasiyana-siyana zvakaita sepaleontology, archaeology, uye genetics. Zvisaririra zvevanhu nemidziyo inowanikwa panzvimbo dzakasiyana-siyana zvinopa ruzivo rwekuti madzitateguru edu akararama sei, akachinja sei, uye akashanduka sei. Semuenzaniso, zvisaririra zvakaita se "Lucy," "Turkana Boy," uye "Neanderthal," pakati pezvimwe, zvinopa ruzivo rwekuchinja kwechimiro uye kugadziriswa kwezvakatipoteredza.
Majini anoitawo basa guru mukunzwisisa kushanduka kwevanhu. Vachishandisa nzira dzemazuva ano dzakadai seDNA sequencing, masayendisiti anogona kuronda madzitateguru evanhu uye hukama huripo pakati pemarudzi akasiyana ehominid. Mitochondrial DNA neY chromosome, semuenzaniso, zvinoshandiswa kugadzirazve kutama kwevanhu kwakapfuura uye kudyidzana kwavo.
Kuwanikwa kwezvishandiso zvematombo, hunyanzvi, nezvimwe zvinhu zvinopawo humbowo hwehunyanzvi hwekuziva netsika dzemadzitateguru edu. Mifananidzo yemapako ine mifananidzo yekare, nzvimbo dzekugara dzekare, uye zvishandiso zvemazuva ese zvakawanikwa nevanochera matongo zvinotipa ruzivo rwehupenyu hwevanhu netsika dzevanhu vekare.
Zvinoreva Zvemagariro Evanhu Uye Zveuzivi
Kunzwisisa kushanduka-shanduka kwevanhu kune zvakunorevawo pamaonero edu isu nenzvimbo yedu muchadenga. Dzidziso yekushanduka-shanduka inopikisa maonero ekusika ayo ave achitonga pfungwa dzevanhu kwemazana emakore uye inopa tsananguro inobva pauchapupu hwemavambo nekukura kwevanhu.
Zvisinei, kunewo gakava nenharo pamusoro pezvinorehwa nedzidziso yekushanduka-shanduka kwezvisikwa munharaunda uye mutsika. Mibvunzo pamusoro pekuzivikanwa, tsika, uye basa revanhu muchadenga inowanzo bva pakufungisisa nezvedzidziso iyi. Semuenzaniso, kunzwisisa kwekuti vanhu vakashanduka kubva kumhuka dzemaprimates kunomutsa mibvunzo pamusoro pezvinoita kuti tive "vanhu" uye kuti tinofanira kutaurirana sei nezvimwe zvinhu zvipenyu.
Mhedziso: Kuenderera Mberi Nekutsvaga Ruzivo
Dzidziso yekushanduka-shanduka kwevanhu, maererano neanthropology, ndeimwe yenzvimbo dzinonakidza uye dzinochinja-chinja dzekudzidza. Humbowo hunoramba huchiwanikwa kubva kumafossil, majini, uye matongo ekare hunopa ruzivo rutsva parwendo rurefu rwevanhu kubva kumadzitateguru emhuka kusvika kuHomo sapiens yemazuva ano. Tsvagiridzo iri kuenderera mberi mundima iyi haingotibatsiri chete kunzwisisa kwatakabva asiwo inokoshesa kuomarara uye kusiyana kwenzvimbo yedu muchadenga.
Neruzivo rwese rwatakawana, tinokurudzirwa kuramba tichiongorora nekutsvagisa zvakadzama nhoroondo yekushanduka-shanduka kwevanhu. Kunzwisisa zviri nani zvakaitika kare kwedu kuchatibatsira kufunga zvakadzama nezveramangwana redu, pamwe nekuvandudza tsika dzedu nekuzivikanwa kwedu semhando yakasiyana pasi pano.
