Ngasekupheleni kwawo-1950, u-Ivan Terence Sanderson, isazi semvelo saseMelika esidume kakhulu, wabelane nge-akhawunti ethakazelisayo mayelana nencwadi ayithola ku-Alan Makshir, unjiniyela omiswe eShemya Island e-Aleutians phakathi ne-WWII.
Lapho u-Alan Makshir kanye nethimba lakhe belethwe umsebenzi wokwakha umugqa wokufika, bacekela phansi amagquma ambalwa bengaqondile futhi bathola amathambo abantu ngaphansi kwezinga elithile lenhlabathi. Bafike endaweni okubonakala sengathi kungcwatshwa kuyo izinsalela zabantu abaningi okubalwa kuzo ugebhezi lwekhanda namathambo.
Kusukela phansi kuye phezulu, ugebhezi olulodwa lwalungamayintshi angu-11 ububanzi nama-intshi angu-22 ubude. Ugebhezi lwekhanda lomuntu omdala lungamayintshi angu-8 ubude ukusuka emuva ukuya phambili. Ugebhezi lwekhanda olukhulu olunjengalolu lungaba impahla yomuntu omkhulu kuphela.
Ngokwesitatimende esinikezwe kule ncwadi, ezikhathini ezikude, imidondoshiya yayinomugqa wesibili wamazinyo kanye nama-flatheads angenangqondo. Ohlangothini olungenhla logebhezi lwekhanda ngalinye, kwakunomgodi ocijile, oqoshwe kahle.
AmaMayya asePeru kanye namaNdiya aseFlathead aseMontana ayevame ukumpintsha ugebhezi lwekhanda losana ukuze aluphoqelele ukuba lukhule lube lude.
UMnu. Sanderson wafuna obunye ubufakazi ngemva kokuthola incwadi yesibili, kodwa uvele waqinisekisa izinsolo zakhe. I I-Smithsonian Institute yayibambe amathambo angaqondakali, ngokwazo zombili izinhlamvu.
UMnu. Sanderson wayazi ukuthi iSmithsonian Institution ingabanikazi bamathambo, futhi wayedidekile ukuthi kungani benqaba ukuveza abakutholile esidlangalaleni. “Abantu abakwazi ukubhekana nokubhalwa kabusha komlando?” ezibuza.
