Iziphumo zomsebenzi upapashwa kwijenali yendalo kunye nendaleko. Ulwimi kunye nezakhono zolwimi zesebe elifanayo loluntu - iNekhartasev - imbambano yexesha elide yokuzivelela kwendalo ye-genus homo (abantu). Emva phayaa ngo-1980s, ithambo le-Nenderthal Bone lafunyanwa kumqolomba wama-Israeli, isifundo esibonisa ukuba kwisakhiwo sayo asifani kumathambo abantu abafanayo.
Ulwahluko olusisiseko kwisakhiwo somlomo ophakathi kweesanti kunye neNekhanderthals ayaziwa. Ke ngoko, ukubakho kuphezulu, njengokuba abo babenezakhono ezifanayo zokuthetha. Nangona kunjalo, ubungqina bokuba uNequerthals unokuthetha ngokuliqonda kwethu ngelizwi, hayi, ke ngoko umbuzo uhlala uvulekile.
Iqela lezinzululwazi, eliquka iingcali ezivela kwi-Alcala i-Alcala i-Alcala (Spain) kunye neBinghemton (i-USA), kunye neKholeji yaseLondon, yaqhuba uphando lwazo. Basebenzise iSigqibo esiPhakamileyo. Ngoncedo lwayo, izazinzulu zazifunda ubume bendlebe yendlebe kunye neNekalarthal, kunye nooyihlo.
Ukongeza, idatha eqokelelwe kwiimodeli ezintathu-ezinesithathu yaziswa kwinkqubo ephuhliswe njengenxalenye ye-bieoengineubineub. Ngenxa yoko, i-atropologhesi yayikwazile ukuvavanya ubuchule bokuva okuba kuthathwa njengeziqwalaselo ukuya kuthi ga kwi-5 khz, egubungela uninzi lwezinto ezininzi zentetho yabantu.
Iziphumo zohlalutyo zibonisile ukuba iiNekhanderthals zazivakala zingcono kwaye zaqonda izandi kuluhlu lwe-4-5 khz ngaphezu kookhokho babo. Kuhlobo ngalunye, kwakwanokwenzeka ukubala uluhlu lwexeshana lobuntununtunu obuphezulu - obizwa ngokuba yi-bandwidth. Imodeli edalwe yeNekhartal ibonise ukuba babenebhendi ebanzi xa kuthelekiswa nookhokho babo.
Ngokutsho kwezazinzulu, oku kucebisa ukuba iNendelarthal yayinenkqubo yokunxibelelana ngokulinganayo, kunye nentetho yomntu yanamhlanje. Kwaye abaphandi bacebise ukuba kwintetho "yabazala" bethu, kukho ubukho obukhulu bezandiso.
