Soo koob maqaalka:  (CNN) Markii la helay lafaha wajiga ee cawlan, ee burburay ee geeska fog ee Itoobiya, arday ka tirsan Jaamacadda Arizona State University ayaa laga yaabaa inay bedeshay fahamkeena ku saabsan awoowayaasheena hore. Qayb ka mid ah daanka hoose waa caddeynta ugu da'da weyn ee la ogaaday ee jilibka Homo, oo dadka casriga ahi ay ka tirsan yihiin, sida lagu sheegay daraasad Arbacadii lagu daabacay joornaalka Science. Xubinta lafaha ayaa la ogaaday in ay jirtay 2.8 milyan oo sano kahor taasoo ka dhigan in lafaha la helay ay ka soo jeedaan qiyaastii 400,000 oo sano sida laga soo xigtay Jaamacada Arizona State. Chalachew Seyoum, oo ah arday qalin jebiyey oo ethiopian ah, ayaa waxa uu helay jawigii-- dhinaca bidix ee daanka hoose kaasoo leh shan ilkood-- intii uu ku guda jiray sahamintiisa deegaanka Afar ee bariga ethiopia sanadkii 2013. "Si daacadnimo ah, waxay ahayd daqiiqad xiiso leh", ayuu yiri Seyoum, sida lagu sheegay war-saxaafadeed ka soo baxay jaamacadda. "Waxaan khibrad fiican u lahaa sahaminta dhulka waxaanan ogaa meesha ay ku yaalliin meelaha ay u badan tahay in ay ku yaalliin. Waxaan fuulay meel buurta dusheeda ah, waxaana helay noocan ah oo ku yaalla geeska buurta". Da'da lafa-goysyada waxay ka dhigan tahay inay gacan ka geysan karto buuxinta nusqaamaha muhiimka ah ee aqoonteena. Kalluumeysatada ayaa helay burbur laga yaabo inuu muujiyo nooc cusub oo bini aadam hore ah. Waxay kaloo macnaheedu tahay, in jilibka bani'aadamka ay is badaleen ku dhowaad nus milyan oo sano ka hor intii la moodayay. Cilmi baadhayaashu waxay horey u heleen burburin soo jirtay 3 milyan oo sano ama ka badan, sida qalfoofka "Lucy", oo ah caan 3.2 milyan oo sano jir ah oo ka tirsan noocyada Australopithecus afarensis. Jidhka waxaa la helay 1974 meelo aan aad ugu fogeyn meeshii la helay. Seynisyahanada ayaa sidoo kale helay lafdhabarta 2.3 milyan oo sano jir ah iyo kuwa ka yar, kuwaas oo ku jira nooca Homo oo aad ugu dhow dadka casriga ah. laakiin ilaa iyo hada, waxa jiray tiro yar oo cadeymo ah oo ah 700,000 oo sano ee ugu danbeysay-- xili aad u muhiim ah isbedelka kasoo bilaawday hidda-wadaagta (hominids) sida Lucy ilaa iyo jilibkii Homo. "Muhiimada tijaabada ayaa ah inay ku darto xogta waqtiga ee awoowayaasheena oo aan xog yar ka hayno", ayuu yiri William H. Kimbel,...
Lafaha jawga waxaa laga helay gobolka Afar ee Itoobiya, meel aan ka fogeyn halka "Lucy" laga helay. Waxaa la ogaaday in ay jirtay 2.8 milyan oo sano taas oo macnaheedu yahay in ay caawinayso buuxinta nusqaamaha muhiimka ah ee aqoonteena.
