Ukuthuthukiswa Kocwaningo Lwezinto Ezivubukulayo Zangaphambi Komlando
Isayensi yezinto zakudala igatsha lesayensi yezinto zakudala eligxile empilweni yabantu ngaphambi kokuba kube khona amarekhodi abhaliwe. Ngenxa yokuthi imibhalo yomlando ayitholakali, abacwaningi kumele "bafunde" isikhathi esidlule ngokusebenzisa imikhondo yezinto ezibonakalayo: amathuluzi amatshe, amathambo, izinsalela zokudla, imidwebo yemihume, izindawo zokuhlala, kanye namaphethini endawo. Ngokuhlanganisa lokhu okutholiwe nezindlela zesayensi ezahlukahlukene, isayensi yezinto zakudala ifuna ukuphendula imibuzo ebalulekile: ukuthi abantu bavela nini, ukuthi basinde kanjani, ukuthi amasiko athuthuka kanjani, nokuthi abantu bathuthela kanjani futhi bazivumelanisa kanjani nezinguquko zemvelo. Ngokuhamba kwesikhathi, ucwaningo kulo mkhakha luye lwathuthuka ngokushesha - ngokwemfundiso, izindlela, kanye nobuchwepheshe - futhi lezi zinguquko ziye zabumba indlela esiqonda ngayo umlando wangaphambi komlando ngokucace nangokulinganisekayo.
Isiqalo: Kusukela Eqoqweni Lezinto Ezisetshenzisiwe Kuya Ekufundweni Kwesayensi
Ukuthuthukiswa kwezinto zakudala zasendulo kwaqala ngomkhuba wokuqoqa izinto zasendulo ngekhulu le-18 kuya ekuqaleni kwekhulu le-19. Izinto eziningi zobuciko zatholakala ngengozi zabe sezigcinwa "njengezinto zakudala" ngaphandle komongo. Lesi sikhathi sasibalulekile, kodwa izindlela zesayensi zazintuleka: izindawo zokutholwa zazingavamile ukuqoshwa ngokunembile, izendlalelo zomhlabathi azihlaziywanga, futhi ubudlelwano phakathi kokutholwa babungaqondakali.
Ushintsho olukhulu lwenzeka lapho ososayensi beqala ukuqaphela ukuthi izinto zobuciko kumele zifundwe ngendlela ehlelekile. Isimiso sokuthi "okujulile, okudala" saba yisisekelo sokusungula ukulandelana kwezikhathi. Ngesikhathi esifanayo, kwavela umqondo wokuthi amathuluzi amatshe, amathambo, nensimbi amelela izigaba zobuchwepheshe ezilandelanayo.
Esinye isenzakalo esibalulekile ekuqaleni kwaba yiSistimu Yezinkathi Ezintathu—iNkathi Yamatshe, Yethusi, kanye Neyensimbi—eyasiza abacwaningi ukuhlukanisa okutholiwe ngokusekelwe ezintweni zokwakha kanye nobuchwepheshe. Nakuba manje kubhekwa njengokulula kakhulu futhi okungafaneleki ngaso sonke isikhathi kuzo zonke izifunda, lolu hlaka lwanikeza isisekelo sezifundo zasendulo zanamuhla: ukuthi ushintsho lwamasiko lungalandelelwa ngokuhlelekile ngobufakazi obuphathekayo.
Ukuthuthukiswa Kwezindlela Zokumba Nezokubhala Amadokhumenti
Lapho kungena ngasekupheleni kwekhulu le-19 nasekuqaleni kwekhulu lama-20, ukumba kwaba yinto ejwayelekile futhi elawulwa kakhulu. Abavubukuli baqala ukusebenzisa amasu okumba ahlukaniswe ngezingqimba, beqopha izindawo zokutholakele, behlela amaphrofayili enhlabathi, futhi behlela okutholakele. Umbhalo omuhle uvumela ukuchazwa okunamandla, njengoba okutholakele kuzimele kodwa kodwa kuhlobene nomongo wendawo kanye nesikhathi.
Kwakuphakathi nalesi sikhathi lapho ukuvubukulwa kwezinto zakudala kwaqala khona njengomkhakha wezifundo ezahlukene. I-Geology yasiza ekuqondeni ukwakheka kwendawo, i-paleontology yasiza ekutholeni izilwane zasendulo, kuyilapho i-physical anthropology yandisa ucwaningo lwabantu bokuqala. Ucwaningo lwangaphambi komlando alusagxilile "ezintweni ezihlukile," kodwa ezindleleni zokuphila: ukudla, indawo yokuhlala, ubuchwepheshe, kanye nokuhleleka komphakathi.
Inguquko Yekhalenda: Kusukela Ekuhlobaneni Kuya Ekupheleleni
Intuthuko ebaluleke kakhulu ocwaningweni lwangaphambi komlando kwaba ukufika kwezindlela zokuqopha umlando eziphelele maphakathi nekhulu lama-20, ikakhulukazi ukuqopha umlando nge-radiocarbon (C-14). Ngenkathi ngaphambilini izazi zemivubukulo zazisho kuphela ukuthi ungqimba A lwalumdala kunongqimba B, manje base bekwazi ukulinganisa ubudala ngeminyaka (ngomkhawulo othile wokungaqiniseki). Lolu guquko lwaguqula isimo somhlaba sangaphambi komlando: izinkolelo eziningi zakudala zokulandelana kwezikhathi zabuyekezwa, okunye ukufuduka kwasheshiswa noma kwancishiswa, futhi ubudlelwano phakathi kwezifunda baba sobala.
Ngaphezu kokuqopha nge-radiocarbon, kuye kwasungulwa amanye amasu okuqopha, njenge-thermoluminescence (yezinto zobumba noma izisekelo ezithile), i-OSL (Optically Stimulated Luminescence) yezisekelo ezigcine zivezwe ekukhanyeni, kanye nezindlela ezisekelwe ochungechungeni lwe-uranium zezinto ezithile ezindaweni ezisemahumeni. Ngokuhlanganisa lawa masu, abavubukuli bangakha izikhathi eziqinile futhi bazihlole.
Ukushintsha Kwezici Embonweni: Okwesiko-Umlando, Okwenqubo, kanye Nokwenqubo Yangemva Kwenqubo
Ukuthuthukiswa kocwaningo lwezinto zakudala zasendulo akugcini nje ngobuchwepheshe, kodwa futhi nangezindlela zokucabanga. Ekuqaleni kwekhulu lama-20, indlela yamasiko nomlando yayivelele: abavubukuli bamamephu amasiko asekelwe ezindleleni zezinto zakudala base behumusha izinguquko njengomphumela wokusabalala noma ukufuduka. Le ndlela yayiwusizo ekwakheni amamephu amasiko, kodwa yayivame ukugcizelela kakhulu ukuhlukaniswa futhi ingachazi "isizathu" soshintsho.
Cishe ngawo-1960, kwavela ukuvubukulwa kwezinto zakudala, kugcizelela izindlela zesayensi, imibono evivinywayo, kanye nendima yemvelo ekwakheni isiko. Abavubukuli baqala ukusebenzisa amamodeli ezomnotho, ezemvelo, kanye nezinhlelo zomphakathi ukuchaza ushintsho: isibonelo, ukuthi isimo sezulu sithonya kanjani amaphethini okuhlala, noma ukuthi ubuchwepheshe buthuthuka kanjani ngaphansi kwezingcindezi eziguquguqukayo.
Ngawo-1980, kwavela ukuvubukulwa kwezinto zakudala ngemva kwenqubo, kugxekwa umbono wokuthi ukuvubukulwa kwezinto zakudala kungaba "ongathathi hlangothi" ngokuphelele futhi kumane kusebenze njengesayensi yemvelo. Le ndlela igcizelela incazelo engokomfanekiso, imibono, ubuwena, ubudlelwano bamandla, kanye nendima yokuhumusha. Ocwaningweni lwangaphambi komlando, ukuvubukulwa kwezinto zakudala kugcizelela ukuthi izinto zakudala azizona nje amathuluzi asebenzayo kodwa zingadlulisela nezindinganiso, isimo, kanye nezinkolelo.
Namuhla, ucwaningo lwangaphambi komlando luvame ukuhlanganisa izindlela eziningi: izincazelo zesayensi ezisekelwe kudatha zisabalulekile, kodwa izici zomphakathi nezingokomfanekiso nazo ziyaqashelwa. Umphumela uwukufunda okucebile kwesikhathi esidlule—hhayi nje ngokuthi “nini” nokuthi “kanjani,” kodwa futhi nokuthi “abantu babekuqonda kanjani ukuphila kwabo.”
Ubuchwepheshe Besimanje: Kusukela Ezithombeni Zesathelayithi Kuya Ku-DNA Yasendulo
Emashumini amabili eminyaka edlule kubonakale ukwanda okukhulu kwamakhono okuvubukula kwasendulo ngenxa yobuchwepheshe. Amasu okubona kude njengezithombe zesathelayithi, izithombe zasemoyeni, kanye ne-LiDAR avumela abacwaningi ukubona izici zezwe okunzima ukuzibona ebusweni—kufaka phakathi amasimu ezolimo, izakhiwo ezingcwatshwe, noma amaphethini okuhlala emahlathini nasezindaweni ezikude. Lobu buchwepheshe buvumela ukuhlola okusheshayo, okubanzi, kanye nokuphazamiseka okuncane kwendawo.
Ezingeni lelabhorethri, ukuhlaziywa kwe-isotope okuzinzile kwamazinyo namathambo kusiza ukulandelela amaphethini okudla (isb., ukubuswa kwamaprotheni ezilwane noma ukusetshenziswa kwezitshalo ezithile) kanye nokuhambahamba (kungakhathaliseki ukuthi abantu bakhulele endaweni efanayo noma bathutheleka). I-Zooarchaeology kanye ne-paleoethnobotany ziyathuthuka ukuze ziqonde ukusebenzisana kwabantu nezilwane nezitshalo, okuhlanganisa ukufuya nokushintsha amasu okuziphilisa.
Intuthuko ephawulekayo kakhulu kube ukutadisha i-DNA yasendulo. Ngokusebenzisa amasampula amathambo noma amazinyo, abacwaningi bangalandelela ubudlelwano bobuhlobo babantu, inani labantu, kanye nokufuduka kwabantu izinkulungwane kuya eminyakeni eyizinkulungwane edlule. I-DNA yasendulo ishintshe izindaba eziningi: ukuxubana kwabantu, imizila yokufuduka eyinkimbinkimbi, kanye nokusebenzisana kwamaqembu okwakunzima ukukubonisa ngaphambilini ngezinto zobuciko zodwa.
Ngaphezu kwalokho, ukumodela kwamakhompyutha kanye nobuhlakani bokwenziwa sekuqala ukusetshenziswa ukucubungula idatha enkulu: ukuhlonza amaphethini ezingcezu zezinto ezenziwe ngezinto, ukubikezela izindawo zesayithi, noma ukwakha kabusha izindawo zasendulo. Ubuchwepheshe abuthathi indawo yomsebenzi wasensimini, kodwa buyandisa ububanzi bemibuzo engaphendulwa.
Ukuziphatha, Ukulondolozwa, kanye Nokuzibandakanya Komphakathi
Ukuthuthukiswa kocwaningo lwemivubukulo yasendulo nakho kuthonywa kakhulu yizinkinga zokuziphatha nezokulondolozwa. Izindawo zangaphambi komlando zisengozini yokulimala okuvela ekuthuthukisweni, ekumbeni izimayini, ezokuvakasha eziningi, kanye nokumba okungekho emthethweni. Ngenxa yalokho, imikhuba yokulondoloza imivubukulo kanye nemivubukulo yokuvimbela, eyenziwa ngaphambi kwamaphrojekthi amakhulu entuthuko, iye yavela.
Ezindaweni eziningi, isayensi yezinto zakudala nayo iya endleleni yokubambisana nemiphakathi yasendaweni. Ucwaningo alusabhekwa njengomzamo wezemfundo kuphela, kodwa luyingxenye ebalulekile yefa lamasiko okudingeka liqondwe ndawonye. Ukuzibandakanya komphakathi kunegalelo ekulondolozweni kwendawo, kucebisa ukuhumusha ngolwazi lwendawo, futhi kuvimbela izingxabano mayelana nobunikazi bezinto ezitholakele.
Ngesikhathi esifanayo, amazinga okushicilelwa kanye nokucaca kwedatha kuya ngokuya kudingwa. Idatha ecacile ivumela ukuhlolwa kabusha kokutholakele, ivimbela izimangalo ngaphandle kobufakazi obuqinile, futhi isheshisa intuthuko yesayensi. Ngokwesimo sangaphambi komlando, lapho imithombo ebhaliwe ivame "ukuthula," ubuqotho bedatha yasensimini buyisihluthulelo.
Iziqondiso Zesikhathi Esizayo Zocwaningo Lwangaphambi Komlando
Esikhathini esizayo, ucwaningo lwezinto zakudala zasendulo cishe luzohlanganisa kakhulu. Imibuzo emikhulu efana nemvelaphi yabantu banamuhla, ukuguquguquka kokufuduka, ukufuywa kwezilwane, ukuguquka kwesimo sezulu, kanye nokuvela kobunzima bezenhlalo kuzophendulwa ngokuhlanganiswa kwedatha yasensimini, ukuhlaziywa kwelabhorethri, kanye nomodeli wekhompyutha. Ngokwandayo, amaphrojekthi ahlanganisa imikhakha eminingi, lapho ososayensi bezinto zakudala besebenza kanye nososayensi bezinto eziphilayo, ososayensi bezinto eziphilayo, ososayensi bezinto eziphilayo, kanye nososayensi bedatha.
Kodwa-ke, izinselele nazo ziyanda. Ukushintsha kwesimo sezulu kusongela izindawo ezisogwini kanye nemihume, izingxabano kanye nokuhweba okungekho emthethweni kusongela izinto zobuciko, kanti izidingo zentuthuko zibeka ingcindezi ezindaweni ezicebile ngezinsalela zasendulo. Ngakho-ke, ikusasa lezinto zakudala zasendulo alixhomekile nje kuphela ekuthuthukisweni kwezobuchwepheshe kodwa futhi nasezinqubweni zokulondolozwa ezinengqondo, imfundo yomphakathi, kanye nokuziphatha kocwaningo.
I-Penutup
Ukuthuthukiswa kocwaningo lwezinto zakudala lwasendulo kubonisa uhambo olude oluvela ekuqoqweni kwezinto zakudala kuya emkhakheni wesayensi oyinkimbinkimbi nobuchwepheshe obuphezulu. Kusukela ekuklanyweni kwezakhiwo kanye nokuqoqwa okuphelele kuya ku-DNA yasendulo kanye nokuzwa okukude, intuthuko ngayinye ivula izendlalelo ezintsha zokuqonda ngabantu namasiko abo ngaphambi komlando obhaliwe. Okubaluleke kakhulu, izinto zakudala zasendulo zifundisa ukuthi isikhathi esidlule asiyona nje i-continuum yesikhathi, kodwa okuhlangenwe nakho komuntu okungalandelelwa ngemikhondo yezinto ezibonakalayo—inqobo nje uma sikufunda ngezindlela ezicophelelayo, ukuhumusha okubucayi, kanye nokuzibophezela ekulondolozweni kwezizukulwane ezizayo.
