Daahfurkan ayaa ah mid naxdin leh sababtoo ah dadku waxay u maleynayaan in Neanderthals ay yihiin kuwo asal ah oo duurjoog ah, laakiin sawiridda godadka in ka badan 60,000 oo sano ka hor waxay u ahayd wax la yaab leh iyaga.
Saynis yahanadu waxay ogaadeen in markii aadanaha casriga ah aysan ku noolayn qaaradda Yurub, Neanderthals waxay sawirayeen stalagmites Yurub.
Daahfurkan ayaa ah mid naxdin leh sababtoo ah Neanderthals waxaa loo arkaa mid fudud oo duurjoog ah, laakiin sawiridda godadka in ka badan 60,000 oo sano ka hor waxay u ahayd waxqabad cajiib ah.
Sawirada godka laga helay saddex god oo ku yaala dalka Spain waxa la sameeyay intii u dhaxaysay 43,000 ilaa 65,000 oo sano ka hor, 20,000 sano ka hor inta aanay dadka casriga ahi soo gaadhin Yurub.Tani waxay xaqiijinaysaa in farshaxanka ay alifeen Neanderthals qiyaastii 65,000 oo sano ka hor.
Si kastaba ha ahaatee, sida laga soo xigtay Francesco d'Errico, oo ah qoraaga qoraaga cusub ee majaladda PNAS, natiijadani waa muran, "maqaal saynis ah ayaa sheegaya in midabadani ay noqon karaan walxo dabiici ah" waana natiijada socodka oksijiinta birta..
Falanqaynta cusub waxay muujinaysaa in halabuurka iyo booska rinjigu aanu ku habboonayn hababka dabiiciga ah.Taa beddelkeeda, rinjiga waxaa lagu dabaqaa buufin iyo afuufis.
Waxa ka sii muhiimsan, qaab-dhismeedkoodu kuma eka shay-baarrada dabiiciga ah ee laga soo qaaday godka, taas oo muujinaysa in midabku ka yimaaddo meel dibadda ah.
Shukaansi tafatiran ayaa muujinaya in midabadaas loo isticmaalay waqtiyo kala duwan, in ka badan 10,000 oo sano.
Sida laga soo xigtay d'Errico oo ka tirsan Jaamacadda Bordeaux, tani "waxay taageertaa mala-awaalka ah in Neanderthals ay halkan yimaadeen marar badan kumanaan sano si ay u calaamadiyaan godadka rinjiga."
Way adag tahay in la is barbar dhigo "farshaxanka" Neanderthals iyo frescoes ay sameeyeen casriyadii hore.Tusaale ahaan, frescoes-ka laga helay godadka Chauvie-Pondac ee Faransiiska waa in ka badan 30,000 oo sano.
Laakin daah-furkan cusub waxa uu soo kordhinayaa cadaymo badan oo muujinaya in nasabka Neanderthal ay dabar go’een ilaa 40,000 oo sano ka hor, iyo in aanay ahayn qaraabada cayriin ee Homo sapiens oo muddo dheer loo sawiray Homo sapiens.
Kooxdu waxay qortay in rinjiyadani aysan ahayn "farshaxan" dareenka cidhiidhiga ah, "laakin waa natiijada ficillada garaafka ee loogu talagalay sii wadida macnaha calaamadda ee booska."
Qaab dhismeedka godka "wuxuu door muhiim ah ka ciyaaray nidaamka calaamadaha ee beelaha Neanderthal qaarkood", inkastoo macnaha calaamadahani ay weli yihiin qarsoodi.
