Ilbaxnimadii hore ee Masaarida waxay had iyo jeer ahayd il yaab leh oo soo jiidasho leh dadka adduunka oo dhan. Laga soo bilaabo Ahraamyadooda iyo macbadyadooda cajiibka ah ilaa hieroglyphs-kooda dahsoon, had iyo jeer waxaa jira wax cusub oo lagu ogaanayo ilbaxnimadan hore. Si kastaba ha ahaatee, daraasad cusub ayaa hadda daaha ka qaaday macluumaad cajiib ah oo ku saabsan mid ka mid ah Fircoonkii ugu caansanaa ee Masar hore. Cilmi-baadhayaashu waxay rumaysan yihiin in hadhaaga Sa-Nakht laga yaabo inuu yahay kii ugu da'da weynaa ee la yaqaan ee aadanaha.
Khuraafaadku waxay ku badan yihiin sheekooyinka Rafaa, laga bilaabo dhaxan iyo dab-demiska halyeeyada Norse ilaa Titans kuwaas oo la dagaallama ilaahyada khuraafaadka Giriigii hore. Si kastaba ha ahaatee, Rafaa waa ka badan oo kaliya khuraafaadka; koritaan degdeg ah iyo korriin xad-dhaaf ah, xaalad loo yaqaan gigantism, waxay dhici kartaa marka jidhku soo saaro hoormoon korriin aad u badan. Tani waxay badanaa ku dhacdaa sababtoo ah buro ku taal qanjirka pituitary ee maskaxda.
Iyaga oo sii wada daraasaddooda baadhiseed ee ku saabsan hooyooyinka, saynisyahannadu waxay sahamiyeen hadhaagii qalfoofkii laga helay 1901 oo ku dhex yaal qabri ku yaal meel u dhow Beit Khallaf ee Masar. Laga soo bilaabo cilmi-baaris hore oo la sameeyay, qiyaasaha ayaa da'da lafahaan dib ugu celiyay Boqortooyada Saddexaad ee Masar, taas oo dhacday qiyaastii 2700 BC.
Shaqadii hore waxay soo jeedisay in qalfoofka ninka - oo istaagi lahaa ilaa 6 cagood 1.6 inji (1.987 mitir) dherer ah - laga yaabo inuu lahaan jiray Sa-Nakht, Fircoon intii lagu jiray Boqortooyada Saddexaad. Cilmi-baaris hore oo lagu sameeyay hooyooyinkii hore ee Masaarida ayaa soo jeediyay celceliska dhererka ragga ee waqtigan wuxuu ahaa ilaa 5 cagood iyo 6 inji (1.7 m), ayuu yidhi la-shaqeeyaha daraasadda Michael Habicht, oo ah khabiir xagga Masar ah oo ka tirsan Jaamacadda Zurich ee Machadka Daawaynta Evolutionary.
Boqorradii hore ee Masaarida waxay u badan tahay inay quudin iyo caafimaad roon yihiin marka loo eego dadka caadiga ah ee waagaas, sidaa darteed waxaa la filan karaa inay ka koraan dherer ka badan celceliska. Weli, dhererka-6-foot-dheer ee hadhaa ee saynisyahannadu ay falanqeeyeen waxay ku kici lahaayeen Ramesses II, Fircoonkii hore ee Masar ugu dheeraa, kaasoo noolaa in ka badan 1,000 sano ka dib Sa-Nakht wuxuuna ahaa kaliya 5 cagood 9 inji (1.75 m) dheer, ayuu yiri Habicht.
Daraasadda cusub, Habicht iyo asxaabtiisu waxay dib u falanqeeyeen lafo la sheegay in Sa-Nakht. Sida laga soo xigtay iyaga, lafaha dhaadheer ee qalfoofka ayaa muujiyay caddaynta "koritaanka aadka u wanaagsan," kuwaas oo ah "calaamadaha cad ee gigantism."
Natiijooyinkani waxay soo jeedinayaan in Masrigii hore ay u badan tahay inuu lahaa gigantism, taasoo ka dhigaysa kiiskii ugu da'da weynaa ee loo yaqaan xanuunkan adduunka, ayay cilmi-baarayaashu sheegeen. Ma jirin boqortooyadii hore ee Masaarida oo loo aqoonin inay yihiin koox weyn.
Habicht waxa uu sheegay in ay muhiim tahay in la barto sida ay cudurradu ugu soo bexeen muddo ka dib dhinaca daawada maanta. Xilliyadii boqortooyadii hore ee Masar, waxay u ekayd in dadka dhererkoodu gaagaaban yahay la jecel yahay oo ay jiraan qaar badan oo iyaga ka mid ah oo ku jira xilal boqornimo. Si kastaba ha ahaatee, sababaha ka dambeeya doorashadan lama hubo.
Xaqiiqda ah in Sa-Nakht lagu aasay si sharaf leh xabaashii mastaba-sare, ka dib markii uu qaan-gaaray, waxay soo jeedinaysaa in gigantism-ka wakhtigaas ay u badan tahay inaysan la xiriirin kala-soocida bulshada, cilmi-baarayaashu waxay yiraahdeen.
