Ubu buvumbuzi buratangaje kuko abantu batekereza ko Abaneyanderthal ari aba kera kandi b’inkazi, ariko gushushanya ubuvumo mu myaka irenga 60.000 ishize byari ikintu gitangaje kuri bo
Abahanga mu bya siyansi bavumbuye ko igihe abantu bo muri iki gihe batari batuye ku mugabane w’u Burayi, Abaneyanderthal bakururaga imite imeze nk’iy’imbeba mu Burayi.
Ubu buvumbuzi buratangaje kuko Abaneyanderthal bafatwa nk'abantu boroshye kandi b'inkazi, ariko gushushanya ubuvumo mu myaka irenga 60.000 ishize byari ikintu gitangaje kuri bo.
Amashusho y’ubuvumo yabonetse mu buvumo butatu muri Esipanye yakozwe hagati y’imyaka 43.000 na 65.000 ishize, imyaka 20.000 mbere y’uko abantu bo muri iki gihe bagera i Burayi. Ibi byemeza ko ubuhanzi bwahimbwe n’Abaneyanderthal mu myaka 65.000 ishize.
Ariko, nk'uko Francesco d'Errico, umwanditsi mushya w'ikinyamakuru cya PNAS abivuga, iki cyegeranyo kiravugwaho rumwe, "inyandiko ya siyansi ivuga ko izi pigment zishobora kuba ari ibintu bisanzwe" kandi ko ari ingaruka z'urujya n'uruza rwa okiside y'icyuma.
Isesengura rishya ryerekana ko imiterere n'aho irangi riherereye bidahuye n'imikorere karemano. Ahubwo, irangi rikoreshwa mu gutera no gusifura.
Icy'ingenzi kurushaho, imiterere yazo ntabwo ihuye n'ingero karemano zakuwe mu buvumo, ibyo bikaba bigaragaza ko ibara rituruka hanze.
Isesengura ryimbitse ry’igihe rigaragaza ko aya mabara yakoreshejwe mu bihe bitandukanye, mu myaka irenga 10.000 itandukanye.
Dukurikije ibivugwa na d'Errico wo muri Kaminuza ya Bordeaux, ibi “bishyigikira igitekerezo cy'uko Abaneyanderthal bagiye baza hano incuro nyinshi mu myaka ibihumbi ishize kugira ngo basige irangi ku buvumo.”
Biragoye kugereranya "ubuhanzi" bw'Abaneyanderthal n'ibishushanyo byakozwe n'abahanga mu mateka ya kera. Urugero, ibishushanyo byabonetse mu buvumo bwa Chauvie-Pondac mu Bufaransa bifite imyaka irenga 30.000.
Ariko ubu buvumbuzi bushya bwongeraho ibimenyetso byinshi byerekana ko umuryango wa Neanderthal wagiye ucika mu myaka 40.000 ishize, kandi ko atari bene wabo ba Homo sapiens bamaze igihe kinini bagaragazwa nka Homo sapiens.
Itsinda ryanditse ko aya mabara atari "ubuhanzi" mu buryo bufunze, "ahubwo ni umusaruro w'ibikorwa by'amashusho bigamije gukomeza ubusobanuro bw'ikigereranyo bw'ahantu."
Inyubako y'ubuvumo "yagize uruhare runini mu buryo bw'ibimenyetso bya bamwe mu baturage ba Neanderthal", nubwo ibisobanuro by'ibi bimenyetso bikiri amayobera.
