Ibisubizo byakazi byatangajwe mu kinyamakuru ibinyamakuru ibitangaza n'ubwihindurize. Ururimi nubushobozi bwindimi bwishami risa nubumuntu - Neanderthasev - Ikibazo kirekire cyihindagurika ryabantu gukora (abantu). Inyuma mu myaka ya za 1980, amagufwa ya Bandery ya Neanderthal yabonetse mu buvumo bwa Isiraheli, ubushakashatsi bwerekanye ko mu nyubako yacyo itandukanye n'ama n'amashyamba asa n'abantu ba none.
Itandukaniro ryibanze muburyo bwo mu kanwa hagati ya sapine na neanderthal ntabwo bizwi. Kubwibyo, birashoboka ko ari hejuru, nkuko nabandi nabandi bakorewe ubushobozi bumwe bwo kuvuga. Ariko, ibimenyetso bifatika byerekana ko Neanderthals ishobora kuvuga mu gusobanukirwa iri jambo, oya, bityo ikibazo kiracyakinguye.
Itsinda mpuzamahanga ry'abahanga, ririmo inzobere muri kaminuza za Alcala (Espanye) na Binghemton (USA), ndetse n'ishuri ryigihe cya FONDON, bakoze ubushakashatsi bwabo. Bakoresheje imyanzuro myinshi yahuye na tomografiya. Abifashijwemo, abahanga bize imiterere ya ugutwi gutwi kwa sapine na Neanderthal, kimwe na basekuruza.
Byongeye kandi, amakuru yakusanyirijwe kuri moderi eshatu-zintangarugero zatangijwe muri gahunda zateye imbere mu rwego rwo kubura ibinyabuzima. Rero, abahanga mu zamuntu bashoboye gusuzuma ubushobozi bwo kuvura ubwoko bwamajwi kugeza kuri 5 KHz, ikubiyemo amateka menshi yimvugo yabantu igezweho.
Ibisubizo by'isesengura byerekanaga ko Neanderthal yumvise neza kandi amenya amajwi mu ntera ya 4-5 khz kuruta abakurambere babo. Kuri buri bwoko, nabwo birashoboka kubara urutonde rwimikorere ntarengwa - ibyo bitagadth. Icyitegererezo cyaremewe Neanderthal cyerekanaga ko bafite igitambaro cyagutse ugereranije na basekuruza.
Nk'uko abahanga bavuga ko ibi byerekana ko Neanderthal yari afite gahunda igoye cyane mu itumanaho, ndetse n'imvugo y'abantu igezweho. Abashakashatsi babisabye ko mu mvugo ya "mubyara" yacu ya mugenzi we mugenzi we, habaye amajwi akomeye.
