Inkqubo yokwenziwa kwe-TamMalian Tishuli efana nokukhula kweetshomi
Iqela labaphandi bamanye amazwe lalifumanise ukuba kumakhonkco e-tiggy, ekhula minyaka le, umntu unokugweba ukutya kwesilwanyana, kunye notshintsho kwimozulu yendawo yokuhlala. Inqaku lenzululwazi livele kwimagazini eNew Atlas.
Kuyaziwa ukuba izicubu ze-navalov ziyakhula ukusuka kwizinyo eliphezulu lamadoda alolu hlobo lwezilwanyana zaselwandle. Amadoda abhinqileyo anesandla, kodwa afihliwe emva kweentsini. Eyona njongo iphambili yokunyuka kwayo kuhlala kungaziwa. Kwinkqubo-sikhokelo yesifundo, izazinzulu zahlalutya ii-testes ezili-10 ezifunyenwe kwi-Inuitov (abantu bomthonyama baseNyakatho), bazingela iNarwalov ekutyeni. Ubude beesampulu ezifundwayo zahluka ukusuka kwi-150 ukuya kwi-248 cm.
Iinyosi zanqunyulwa kunye nophando oluneenkcukacha lokukhula kwamakhonkco. Iringi ibonakalisa iinkalo zonyaka omnye wobomi. Abaphandi baqhuba imilinganiselo yenqanaba le-Mercury, kunye ne-hitrogen kunye ne-scobns kwi-Itopes nganye yonyaka, eyenze ukuba ikwazi ukufumanisa ukutya okuphambili kwe-ice okanye kulwandle oluvulekileyo .
Iqela lafumanisa ukuba ngethuba ukuya kuthi ga kwiminyaka yo-1990, isiseko sokutya kwe-navalov yayiyi-Arctic Cod kunye ne-halolous, kufutshane ne-ice yolwandle. Ngelo xesha, i-ice pokrov yayinesikwere esikhulu, kodwa wayesoloko etshintsha. Njengoko umkhenkce we-Ice Diser Ukususela ngo-1990 ukuya ku-2000, izilwanyana zanyanzelwa ukuba ziye kulwandlekazi oluvulekileyo ukufumana ukutya. Oku kukhokelele kwinani le-Mercury kwi-mammalian. Iingcali zibonisa ukuba unobangela weenkqubo ezinjalo yayikukunqongo oluphezulu kwe-Mercury kwi-emveliso evuthayo ngexesha elivuthayo laseMzantsi-mpuma eMzantsi-mpuma yeAsia.
Ngokutsho kombhali ophambili wokufunda kwe-rue ditz, ngoku izazinzulu zaziwa ukuba kukho ibhanki yedatha exabisekileyo kwiinkqubo zemozulu kwi-Arctic Retic. Uphononongo lwabo aluyi kuvumela ukufumana umbono wezicwangciso ezahlukeneyo zesondlo, kodwa ikwaqonde indlela abaziqhelanisa ngayo kwindawo abahlala kuyo okwangoku.
