Imiphumela yomsebenzi ishicilelwe ejeni lemvelo yemvelo kanye nokuziphendukela kwemvelo. Amakhono olimi kanye namalimi wegatsha elihambisanayo lesintu - i-Neangerthasev - umagazini isikhathi eside wokuvela kwemvelo ye-genus homo (abantu). Emuva ngawo-1980s, ithambo eliphansi likaNeanderthal litholwe emhumeni wakwa-Israyeli, isifundo sawo esibonisa ukuthi esakhiweni saso akuhlukile kumathambo afanayo abantu banamuhla.
Amanye umehluko oyisisekelo esakhiweni somlomo womlomo phakathi kwama-sapires nama-neanderthals awaziwa. Ngakho-ke, amathuba aphakeme, njengoba lezo kanye nabanye babenamandla afanayo okukhuluma. Kodwa-ke, ubufakazi obuqondile bokuthi amaNeanderthals angakhuluma ngokuqonda kwethu leli gama, cha, ngakho-ke umbuzo uhlala uvulekile.
Iqembu lamazwe aphesheya, elalihlanganisa ochwepheshe abavela kuma-alcala amanyuvesi (Spain) neBinghemton (USA), kanye ne-Imperial College yaseLondon, baqhuba owabo ucwaningo. Basebenzise i-tomography ephezulu. Ngosizo lwayo, ososayensi bafunda ukwakheka kwendlebe yendlebe e-Sperires naseNeanderthal, kanye nokhokho babo.
Ngaphezu kwalokho, imininingwane eqoqwe ngamamodeli anezici ezintathu yangeniswa ohlelweni oluthuthukiswe njengengxenye ye-bioengineerring ezwayo. Ngakho-ke, izazi ze-anthropologists zakwazi ukuhlola amakhono okuzwa ezinhlamvu ezithathwa njenge-5 KHZ, ezimboza iningi lezinci eziningi zenkulumo yabantu yesimanje.
Imiphumela yokuhlaziywa iveze ukuthi amaNeanderthals azwakala kangcono futhi aqashelwa imisindo ebangeni lama-4-5 Khz kunawo okhokho babo. Ngohlobo ngalunye, kungenzeka futhi ukubala uhla lwemvamisa lokuzwela okuphezulu - okuthiwa yi-bandwidth. Imodeli eyenzelwe uNeanderthal iveze ukuthi babene-bandwidth ebanzi uma kuqhathaniswa nokhokho babo.
Ngokusho kososayensi, lokhu kusikisela ukuthi uNeanderthal waba nesistimu eyinkimbinkimbi yokuxhumana, kanye nenkulumo yesimanje yabantu. Futhi abaphenyi basikisela ukuthi enkulumweni yabazala bethu bakini, kwaba khona okukhulu kwemisindo yokukhohlisa.
