Ubu buvumbuzi buratangaje kuko abantu batekereza ko Neanderthals ari primite kandi ni inyamanswa, ariko gushushanya ubuvumo hashize imyaka irenga 60.000 byari ibintu bitangaje kuri bo
Abahanga bavumbuye ko mugihe abantu ba kijyambere batatuye kumugabane wu Burayi, Neanderthal yashushanyaga stalagmite i Burayi.
Ubu buvumbuzi buratangaje kuko Neanderthals ifatwa nkibyoroshye kandi byubugome, ariko gushushanya ubuvumo hashize imyaka irenga 60.000 byari ibintu bitangaje kuri bo.
Igishushanyo cy’ubuvumo kiboneka mu buvumo butatu muri Espagne cyakozwe hagati yimyaka 43.000 na 65.000, hashize imyaka 20.000 mbere yuko abantu ba none bagera mu Burayi.Ibi biremeza ko ubuhanzi bwahimbwe na Neanderthals hashize imyaka 65.000.
Icyakora, nk'uko byatangajwe na Francesco d'Errico, umwe mu banditsi b'impapuro nshya mu kinyamakuru PNAS, ngo iki cyegeranyo ntikivugwaho rumwe, "ingingo ya siyansi ivuga ko izo pigment zishobora kuba ibintu bisanzwe" kandi bikaba ari ingaruka ziterwa na okiside ya fer..
Isesengura rishya ryerekana ko ibigize hamwe nu mwanya w irangi bidahuye nibikorwa bisanzwe.Ahubwo, irangi rikoreshwa mugutera no guhuha.
Icy'ingenzi cyane, imiterere yabyo ntabwo ihuye nurugero rusanzwe rwakuwe mubuvumo, byerekana ko pigment ituruka hanze.
Kurambagiza birambuye byerekana ko izo pigment zakoreshejwe ahantu hatandukanye mugihe, imyaka irenga 10,000.
Nk’uko bitangazwa na d'Errico wo muri kaminuza ya Bordeaux, ngo “ibi bishyigikira igitekerezo cy'uko Neanderthal yaje hano inshuro nyinshi mu myaka ibihumbi n'ibihumbi kugira ngo berekane ubwo buvumo amarangi.”
Biragoye kugereranya "ubuhanzi" bwa Neanderthal na frescoes zakozwe na kijyambere.Kurugero, ibishushanyo biboneka mu buvumo bwa Chauvie-Pondac mu Bufaransa bimaze imyaka irenga 30.000.
Ariko ubu buvumbuzi bushya bwongeyeho ibimenyetso byinshi byerekana ko ibisekuru bya Neanderthal byazimye hashize imyaka igera ku 40.000, kandi ko atari bene wabo batagira ingano ba Homo sapiens kuva kera bagaragazwa nka Homo sapiens.
Iri tsinda ryanditse ko aya marangi atari “ubuhanzi” mu buryo bugufi, “ahubwo ni ibisubizo by'ibishushanyo mbonera bigamije gukomeza ubusobanuro bw'ikigereranyo cy'umwanya.”
Imiterere y'ubuvumo "yagize uruhare runini muri sisitemu y'ibimenyetso ya bamwe mu baturage ba Neanderthal", nubwo ibisobanuro by'ibi bimenyetso bikiri amayobera.
