Waxay bixisaa macluumaad dheeraad ah oo ku saabsan sida uu ninku ku yimid
Ilmo yar oo jira ugu yaraan 130,000 oo sano, laga helay god ku yaal Laos, ayaa ka caawin kara saynisyahannadu inay helaan macluumaad dheeraad ah oo ku saabsan ilmo-adeerkii hore ee jinsiga, sida lagu sheegay daraasad lagu daabacay Nature Communications. Cilmi-baadhayaashu waxay rumaysan yihiin in daahfurka uu caddaynayo in Denisovans - laantii dabar-goynta ee bini'aadamka - ay ku noolaayeen kulaylka diiran ee Koonfur-bari Aasiya.
Wax aad u yar ayaa laga yaqaan Denisovans, ilma adeer ee Neanderthals. Saynis yahanada ayaa markii ugu horeysay helay iyaga oo ka shaqaynayay godka Siberian sanadkii 2010kii, waxaanay heleen laf farta gabadh ka tirsan koox dad ah oo ilaa hadda aan la aqoonsan. Iyaga oo isticmaalaya kaliya ciidda iyo xikmadda laga helay Denis Cave, waxay soo saareen dhammaan genome-ka kooxda.
Kadib sanadka 2019, cilmi-baarayaashu waxay ka heleen lafta daanka ee Tibetan Plateau, taasoo caddaynaysa in noocyada qaar ay sidoo kale ku noolaayeen Shiinaha. Marka laga reebo fossils-ka dhifka ah, ninka Denisovan wax raad ah kama tagin ka hor inta uusan lumin - marka laga reebo hiddo-wadaha DNA-da aadanaha ee maanta. Thanks to taranka Homo sapiens, hadhaagii ninka Denisovan waxaa laga heli karaa dadka hadda ku nool Koonfur Bari Aasiya iyo Oceania. Aborigines iyo dadka ku nool Papua New Guinea waxay leeyihiin ilaa shan boqolkiiba DNA-da noocyadii hore.
Saynis yahanadu waxay soo gabagabeeyeen in "awoowayaasha casriga ah ee dadkan ay ahaayeen" isku dhafan "Denisovans ee Koonfur Bari Asia," ayuu yiri Clement Zanoli, paleoanthropologist iyo qoraaga daraasadda. Laakiin ma jirto "caddayn jireed" oo ku saabsan joogitaankooda qaybtan ka mid ah qaaradda Aasiya, oo ka fog buuraha barafka ah ee Siberiya ama Tibet, cilmi-baaraha Xarunta Cilmi-baarista Qaranka ee Faransiiska ayaa u sheegay AFP.
Tani waxay ahayd ilaa koox saynisyahano ah ay bilaabeen inay daraasad ku sameeyaan hadhaagii Godka Cobra ee waqooyi bari Laos. Khubarada godka ayaa sannadkii 2018 ka helay dhulka buuraleyda ah ee ku dheggan godka Tam Pa Ling, halkaas oo hadhaagii dadkii hore laga helay. Isla markiiba waxay soo baxday in iliggu leeyahay qaab "caadi ahaan aadanaha", ayuu yiri Zanoli. Daraasaddu waxay sheegtay in daraasadda borotiinnada qadiimiga ah ay muujinayso in iligu ay leeyihiin ilmo, malaha gabadh, da'dooduna u dhaxayso 3.5 ilaa 8.5 sano. Ka dib markii ay falanqeeyeen qaabka iliga, saynisyahannadu waxay aaminsan yihiin in ay u badan tahay Denisovans oo ku noolaa godka 164,000 ilaa 131,000 sano ka hor.
