Sida laga soo xigtay a Phys.org Warbixinta, tiro badan oo lafo xayawaan ah oo 40,000-sano jir ah ayaa laga helay heerka saddexaad ee Cueva Des-Cubierta ee Spain oo uu qoray Enrique Baquedano oo ka tirsan Matxafka Archaeology iyo Paleontology ee Madrid iyo asxaabtiisa.
Wargeyskooda oo lagu daabacay joornaalka Nature Human Behavior, kooxdu waxay ku qeexday goobta laga helay madaxyada, xaaladooda iyo aragtiyaha ku saabsan sababta madaxyada loo dhigay godka.
Godka Cueva Des-Cubierta ee ku yaalla gobolka Madrid ee dalka Spain ayaa markii ugu horreysay la helay sannadkii 1978. Ilaa wakhtigaas, hadhaagii ilma Neanderthal iyo qalab ay sameeyeen Neanderthals ayaa laga helay godka kala duwan. Lafaha cusub ee la helay ayaa waxaa ka mid ah noocyo kala duwan oo ah madaxyada herbivore-ka ah oo si taxadar leh looga soo saaray jirka xayawaanka oo lagu beddelay qalab iyo mararka qaarkood dab, ayuu yiri Baquedano.
Inta badan dhafoofyada waxaa iska lahaa bison ama aurochs, kuwaas oo geeso leh; deero lab ah oo qudhaanjo leh; iyo laba wiyil. Cilmi-baarayaashu waxay xuseen in dhafoorrada ay bixin lahaayeen cunto yar, lagana yaabo in loo badbaadiyo sidii koobabka ugaarsiga, ama ay u adeegi karaan ujeeddo aan la garanayn.
