Inikela inkcazelo engakumbi ngendlela umntu abekho ngayo
Izinyo lomntwana ubuncinane iminyaka eyi-130,000 ubudala, elifunyenwe kumqolomba waseLaos, linokunceda izazinzulu ukuba zifumane ulwazi oluthe kratya malunga nomzala wokuqala woluntu, ngokutsho kophando olupapashwe kwiNdalo yoNxibelelwano. Abaphandi bakholelwa ukuba ukufumanisa kungqina ukuba iDenisovans - isebe elingasekhoyo loluntu - lalihlala kwindawo eshushu yase-Asia-mpuma.
Kuncinci kakhulu okwaziwayo malunga neDenisovans, abazala beNeanderthals. Iingcali zenzululwazi zaqala ukuzifumana ngelixa zisebenza kumqolomba waseSiberia ngo-2010 kwaye zafumana ithambo lomnwe wentombazana eyinxalenye yeqela labantu abangaziwayo. Ukusebenzisa kuphela umhlaba kunye ne-sage efunyenwe kwi-Denis Cave, bakhupha yonke i-genome yeqela.
Ke ngo-2019, abaphandi bafumana umhlathi kwiThafa laseTibetan, ebonisa ukuba ezinye zeentlobo zazihlala eTshayina. Ngaphandle kwezi ntsalela zinqabileyo, indoda yaseDenisovan yashiya phantse ingabikho mkhondo ngaphambi kokuba yanyamalala - ngaphandle kwemfuza yeDNA yomntu yanamhlanje. Enkosi ekudibaneni kunye neHomo sapiens, iintsalela zendoda yaseDenisovan zinokufumaneka kubemi bangoku eMzantsi-mpuma Asia naseOceania. Abemi bomthonyama nabantu basePapua New Guinea bane-DNA efikelela kwisihlanu ekhulwini kwizinto zamandulo.
Izazinzulu ziye zagqiba kwelokuba "izinyanya zanamhlanje zaba bantu" zazixutywe "neeDenisovans kuMzantsi-mpuma Asia," utshilo uClement Zanoli, isazi sembali kunye nombhali odibeneyo wophononongo. Kodwa akukho "ubungqina obubonakalayo" bobukho babo kule nxalenye yelizwekazi laseAsia, kude neentaba ezibandayo zaseSiberia okanye eTibet, umphandi ovela kwiZiko loPhando leSizwe laseFransi uxelele i-AFP.
Oku kwenzeka de iqela lezazinzulu laqalisa ukufunda iintsalela zoMqolomba weCobra kumntla-mpuma weLaos. Iingcali zomqolomba zafumanisa indawo ezintabeni ngo-2018 ecaleni komqolomba uTam Pa Ling, apho sele kufunyenwe iintsalela zabantu bamandulo. Kwangoko kwavela ukuba eli zinyo linemilo “eqhelekileyo yomntu,” uchaza uZanoli. Uphononongo luthi uphononongo lweeproteni zamandulo lubonisa ukuba izinyo lelomntwana, mhlawumbi intombazana, eneminyaka ephakathi kwe-3.5 kunye ne-8.5 yeminyaka. Emva kokuhlalutya indlela elime ngayo izinyo, izazinzulu zikholelwa ukuba kusenokwenzeka ukuba abantu baseDenisovans ababehlala kulo mqolomba kwiminyaka eyi-164,000 ukuya kwi-131,000 eyadlulayo.
