Limapereka chidziŵitso chowonjezereka cha mmene munthu anakhalira
Dzino la khanda la zaka zosachepera 130,000, lopezeka m'phanga ku Laos, lingathandize asayansi kupeza zambiri zokhudza msuweni wakale wa mtundu wa anthu, malinga ndi kafukufuku wofalitsidwa mu Nature Communications. Ofufuza akukhulupirira kuti zomwe apezazi zikutsimikizira kuti a Denisovans - nthambi yomwe yatha - amakhala kumadera otentha a Southeast Asia.
Zochepa kwambiri zimadziwika za a Denisovans, azibale a Neanderthals. Asayansi adawapeza koyamba akugwira ntchito m'phanga la ku Siberia mu 2010 ndipo adapeza fupa la chala la mtsikana wa gulu lomwe silikudziwika mpaka pano. Pogwiritsa ntchito dothi ndi tchire lokhalo lomwe limapezeka ku Denis Cave, adatulutsa matupi onse a gululo.
Kenako mu 2019, ofufuza adapeza nsagwada ku Tibetan Plateau, kutsimikizira kuti mitundu inayi inkakhalanso ku China. Kupatula zinthu zakale zosowa izi, bambo wa Denisovan sanasiye chilichonse asanazimiririke - kupatula mu majini a DNA yamunthu lero. Chifukwa cha kuswana ndi Homo sapiens, zotsalira za munthu wa Denisovan zimapezeka m'madera omwe alipo ku Southeast Asia ndi Oceania. Aaborijini ndi anthu a ku Papua New Guinea ali ndi DNA yokwana XNUMX peresenti ya zamoyo zakale.
Asayansi atsimikiza kuti "makolo amakono a anthuwa anali" osakanikirana "ndi a Denisovans ku Southeast Asia," anatero Clement Zanoli, katswiri wa paleoanthropologist komanso wolemba nawo kafukufukuyu. Koma palibe "umboni weniweni" wa kupezeka kwawo kudera lino la Asia, kutali ndi mapiri oundana a Siberia kapena Tibet, wofufuza wochokera ku French National Research Center anauza AFP.
Izi zinachitika mpaka pamene gulu la asayansi linayamba kufufuza mabwinja a Cobra Cave kumpoto chakum’maŵa kwa Laos. Akatswiri a mphanga adapeza malowa m'mapiri mu 2018 pafupi ndi phanga la Tam Pa Ling, pomwe zotsalira za anthu akale zidapezeka kale. Nthawi yomweyo zidapezeka kuti dzinolo linali ndi mawonekedwe "wamunthu", Zanoli akufotokoza. Kafukufukuyu akuti kafukufuku wokhudza mapuloteni akale akusonyeza kuti dzinolo ndi la mwana, mwina mtsikana wazaka zapakati pa 3.5 ndi 8.5. Atapenda mawonekedwe a dzinolo, asayansi akukhulupirira kuti n’kutheka kuti anthu a ku Denisovan ankakhala m’phangamo zaka 164,000 mpaka 131,000 zapitazo.
