I-Indonesia yafumana umzobo oneminyaka engama-44.000 ubudala
Umzobo owafunyanwa eludongeni lomqolomba waseIndonesia oneminyaka engama-44.000 wafunyanwa.
Ubugcisa bubonakala ngathi buzingela inyathi xa izingelwa zizidalwa eziyinxalenye yabantu, ngokuyinxenye izilwanyana ezibambe imikhonto mhlawumbi neentambo.
Abanye abaphandi bacinga ukuba imeko inokuba lelona bali lakudala kwihlabathi.
Iziphumo zazisiwe kulindixesha weNdalo ngoochwephesha bezinto zakudala abavela kwiYunivesithi yaseGriffith eBrisbane, e-Australia.
UAdam Brumm - umembi wezinto zakudala waseGriffith - waqala ukuzibona iifoto kwiminyaka emibini edlulileyo emva kokuba umntu asebenza naye e-Indonesia waphosa umkhiwane ukufikelela kumqolomba.
"Le mifanekiso ivele kwi-iPhone yam," utshilo uBrumm. "Ndicinga ukuba ndithethe igama elinobumba abane baseOstreliya ngokuvakalayo."
Uyilo lwaseIndonesia aluyonto indala emhlabeni. Kunyaka ophelileyo, oososayensi bathi bafumene "owona mfanekiso mdala woluntu" kwisiqwenga selitye eMzantsi Afrika, esukela kwiminyaka engama-73.000 eyadlulayo.
Ibonisa ntoni imizobo?
Imizobo yafunyanwa kumqolomba obizwa ngokuba yiLeang Bulu'Sipong 4 emazantsi eSulawesi, isiqithi saseIndonesia kwimpuma yeBorneo.
Iphaneli iphantse ibe ziimitha ezintlanu ububanzi kwaye ibonakala ibonisa uhlobo lwe-buffalo ebizwa ngokuba yi-anoa, ukongeza kwihagu zasendle ezifumaneka eSulawesi.
Ecaleni kwabo ngamanani amancinci ajongeka njengabantu- kodwa zikwanazo neempawu zezilwanyana ezinje ngemisila kunye neempuphu.
Kwelinye icandelo, i-anoa ifakwa uphawu ngamanani amaninzi aphethe imikhonto.
“Andizange ndiyibone into enje ngaphambili,” utshilo uBrumm. "Ndiyathetha, siye sabona amakhulu eziza zobugcisa bamatye kule ngingqi - kodwa asikaze siyibone into enje ngokuzingela."
Nangona kunjalo, abanye abaphandi bazibuze ukuba ngaba ipaneli imele ibali elinye kwaye ithi ingaba luthotho lwemifanekiso epeyintiweyo ixesha elide.
UPaul Pettitt, umembi wezinto zakudala kunye nengcali yobugcisa bamatye kwiYunivesithi yaseDurham, uxelele indalo.
Sazi njani ukuba sineminyaka engama-44.000 ubudala?
Iqela lihlalutye i-popcorn "ye-popcorn" eqokelelwe kumzobo.
I-uranium ene-radioactive kwi-ore icotha kancinci ukuya kwi-thorium, ke iqela lilinganise amanqanaba ee-isotop ezininzi zezi zinto.
Bafumanisa ukuba i-calcite kwihagu yaqala ukwenza ubuncinci kwiminyaka engama-43.900 eyadlulayo, kwaye iidipozithi kwizibini ze-buffaloes zazineminyaka engama-40.900, XNUMX ubudala.
Ubuncinane kukho imiqolomba engama-242 okanye iindawo zokufihla intloko ezinemifanekiso yakudala eSulawesi kuphela-kwaye iindawo ezintsha ziyafunyanwa minyaka le.
Ngaba ithelekiswa njani nezinye izinto zembali?
Isenokungabi lolona lwakhiwo ludala, kodwa abaphandi bathi isenokuba lelona bali lakudala likho.
"Ngaphambili, ubugcisa bamatye obufunyanwa kwiindawo zase-Yuropu ezazisusela kwiminyaka eyi-14.000 ukuya kuma-21.000 kwiminyaka eyadlulayo zazithathwa njengowona msebenzi mdala webali ehlabathini," latsho iphepha kwiNdalo.
Uyilo lukaSulawesi lusenokuba lolona hlobo ludala lwesilwanyana olufumeneyo.
Kunyaka ophelileyo, ipeyinti yomqolomba eBorneo - ekukholelwa ukuba yeyona indala kwezilwanyana - yafunyanwa ineminyaka engama-40.000 ubuncinci ubudala.
