I-Atacama Skeleton: Ithini Ukuhlaziywa KweDNA Ngalo Mama Omncane "ongumfokazi"?

Emuva ngonyaka we-2003, indoda yaseChile egama layo lingu-Oscar Muñoz yathola amathambo amancane angajwayelekile abizwa nge-Ata, eduze kwesonto elidala edolobheni elingenamuntu laseLa Noria, elisogwadule lwase-Atacama.

Yaqala ukubonakala ezinhlelweni ze-TV kanye nedokhumentari ethi, “Sirius,” lapho umcwaningi we-UFO ezama ukuthola umsuka ka-Ata.

Isakhiwo esingu-15cm ubude sibonakala siwuhlaka lwamathambo omuntu oluphelele, futhi ukuhlaziya okuyinhloko kwe-DNA kwabonisa ukuthi kwakuwumzimba womuntu wesifazane.

Kunemibono eminingana mayelana nokuguqulwa kwe-Ata, usayizi kanye nokuma kwakhe. Iningi labo liphakamisa ukuthi u-Ata wayewumbungu womuntu owazalwa ngaphambi kwesikhathi kakhulu ukuba uphile. Nakuba, eminye imibono ethakazelisayo isikisela ukuthi uhlaka lwamathambo lungaba izinsalela zomuntu ongaphandle komhlaba.

I-Atacama Skeleton: Ithini ukuhlaziywa kwe-DNA ngalo mama omncane "ongaziwa"? 1 — Izinsalela zokufuna ukwazi zadonsa iso likaHarry Nolan, uprofesa we-microbiology kanye ne-immunology e-Stanford University eCalifornia, ozinikele ukusiza ukuzifunda. Ku-2013, waphetha ngokuthi u-Ata wayengumuntu, kodwa izizathu zokukhubazeka okuphawulekayo zazingakaqondwa. © Umqaphi

Ngokwemithombo, ososayensi benza amathani ezifundo nezivivinyo ku-Ata, kodwa abakwazanga ukwembula imfihlakalo ephelele ezungeze lolu hlaka lwamathambo oluyinqaba oluyinqaba.

Ngemva kokuhlola ama-x-ray, abacwaningi baphetha ngokuthi ukuthuthukiswa kwamathambo ka-Aka, okusekelwe ebuningini bamapuleti e-epiphyseal amadolo (amapuleti okukhula ekupheleni kwamathambo amade atholakala kuphela ezinganeni), ngokumangalisayo kubonakala sengathi ilingana ne-6- kumntwana oneminyaka engu-8. Uma lokho kubambelela, kunamathuba amabili: okukodwa, isibhamu eside, ukuthi u-Ata wayenohlobo olunzima lobuncane, empeleni wazalwa engumuntu omncane, futhi waphila kwaze kwaba yileso sikhathi sekhalenda. © Ezasendulo

Ngenkathi ngoMashi 2018, ababhali bocwaningo olususelwa eminyakeni emihlanu yokuhlaziywa kwe-genomic bashiwo kujenali. I-Genome Research ukuthi “u-Ata ungumuntu, nakuba unezinguquko eziningi ezihambisana nesifo samathambo.”

Ucwaningo luphinde luthi, umbungu ube nenkinga yokuguga engavamile, kanye nokunye ukuguquka kofuzo okuhambisana nesifo. ubufushane, i-scoliosis, nokungajwayelekile kwemisipha nohlaka lwamathambo.

Abacwaningi baye babona ukuguqulwa okungajwayelekile kwe-64 ezakhini zofuzo ezihlukene ze-7 ezixhunywe ohlelweni lwamathambo, futhi baqaphela ukuthola ukuguqulwa okuhlukahlukene okuthinta ngokuqondile ukuthuthukiswa kwamathambo akukaze kubikwe ngaphambili.

Kulezi zinsuku, izinsalela zifakwe eqoqweni elizimele eSpain, kanti umnikazi wamanje nguRamón Navia-Osorio, usomabhizinisi waseSpain, owayethenge le ngxenye eyingqayizivele ku-Oscar Muñoz.
