Daahfurkan waa mid naxdin leh sababtoo ah dadku waxay u maleynayaan in Neanderthals ay yihiin kuwo asal ah oo aad u xun, laakiin sawiridda godadka in ka badan 60,000 oo sano ka hor waxay ahayd wax cajiib ah iyaga.
Saynisyahannadu waxay ogaadeen in markii aadanuhu casriga ahi aysan ku noolayn qaaradda Yurub, Neanderthals ay Yurub ka sawirayeen stalagmites.
Daahfurkan waa mid naxdin leh sababtoo ah Neanderthals waxaa loo arkaa kuwo fudud oo aad u xun, laakiin sawiridda godadka in ka badan 60,000 oo sano ka hor waxay u ahayd wax cajiib ah.
Sawirrada godka ee laga helay saddex god oo ku yaal Spain waxaa la sameeyay intii u dhaxaysay 43,000 iyo 65,000 oo sano ka hor, 20,000 oo sano ka hor ka hor inta aadanuhu casriga ahi imaan Yurub. Tani waxay xaqiijinaysaa in farshaxanka ay hindiseen Neanderthals qiyaastii 65,000 oo sano ka hor.
Si kastaba ha ahaatee, sida laga soo xigtay Francesco d'Errico, oo ah qoraaga maqaal cusub oo ku jira majaladda PNAS, natiijadan waa mid muran dhalisay, "maqaal cilmiyeed ayaa sheegaya in midabyadani ay noqon karaan walax dabiici ah" waana natiijada socodka oksaydhka birta.
Falanqayn cusub ayaa muujinaysa in qaab-dhismeedka iyo booska rinjigu ay la jaanqaadayaan hababka dabiiciga ah. Taa beddelkeeda, rinjiga waxaa lagu buufiyaa oo la afuufaa.
Waxaa ka sii muhiimsan, qaabkoodu ma la mid aha muunadaha dabiiciga ah ee laga soo qaaday godka, taas oo muujinaysa in midabku ka yimaado ilo dibadda ah.
Daawashada faahfaahsan waxay muujinaysaa in midabyadan loo isticmaalay waqtiyo kala duwan, in ka badan 10,000 oo sano oo isku jira.
Sida laga soo xigtay d'Errico oo ka tirsan Jaamacadda Bordeaux, tani "waxay taageertaa mala-awaalka ah in Neanderthals ay halkan yimaadeen dhowr jeer kumanaan sano si ay godadka ugu calaamadeeyaan rinji."
Way adag tahay in la barbar dhigo "farshaxanka" Neanderthals iyo frescoes ay sameeyeen casrigan qadiimiga ah. Tusaale ahaan, frescoes-ka laga helay godadka Chauvie-Pondac ee Faransiiska waxay jiraan in ka badan 30,000 oo sano.
Laakiin daahfurkan cusub wuxuu sii kordhinayaa caddayn dheeraad ah oo muujinaysa in abtirsiinta Neanderthal ay baaba'day qiyaastii 40,000 oo sano ka hor, iyo inaysan ahayn qaraabada aan caadiga ahayn ee Homo sapiens ee muddo dheer loo sawiray Homo sapiens.
Kooxdu waxay qortay in rinjiyeyntani aysan ahayn "farshaxan" macnaha cidhiidhiga ah, "laakiin ay yihiin natiijada ficillada sawir-gacmeedka ee loogu talagalay in lagu sii wado macnaha astaaneed ee booska."
Qaab-dhismeedka godka "wuxuu door muhiim ah ka ciyaaray nidaamka astaamaha ee bulshooyinka Neanderthal qaarkood", inkastoo macnaha calaamadahani uu weli yahay mid qarsoon.
