Kusuntha kwa anthu kudutsa Nyanja ya Bering kuchokera kumpoto kwa Asia kupita ku North America ndizochitika zodziwika bwino m'mbiri yakale ya anthu. Komabe, mapangidwe a majini a anthu omwe ankakhala kumpoto kwa Asia panthawiyi akhala akudziwikabe chifukwa cha chiwerengero chochepa cha ma genome akale omwe adafufuzidwa kuchokera kuderali. Tsopano, ofufuza omwe adapereka lipoti mu Current Biology pa Januware 12 akufotokoza za ma genomes kuchokera kwa anthu khumi mpaka zaka 7,500 omwe amathandizira kudzaza kusiyana ndikuwonetsa kutuluka kwa jini kuchokera kwa anthu omwe akuyenda kudera lina kuchokera ku North America kupita ku North Asia.
Kusanthula kwawo kukuwonetsa gulu lomwe silinatchulidwepo kale la anthu oyambilira a Holocene Siberia omwe amakhala mdera la Neolithic Altai-Sayan, pafupi ndi komwe Russia, China, Mongolia, ndi Kazakhstan amasonkhana. Zambiri za majini zikuwonetsa kuti anali mbadwa za anthu a paleo-Siberian komanso Ancient North Eurasian (ANE).
Cosimo Posth wa payunivesite ya Tübingen, Germany anati: “Timalongosola za anthu osaka alenje omwe sankadziwika kale ku Altai kuyambira zaka 7,500, zomwe ndi zosakanizika pakati pa magulu awiri osiyana omwe ankakhala ku Siberia m'nyengo ya Ice Age. ndi wolemba wamkulu wa phunziroli. "Gulu la alenje la Altai lidathandizira anthu ambiri omwe adakhalako panthawiyo komanso ku North Asia, zomwe zikuwonetsa momwe madera osoŵawo analili abwino."
Posth akunena kuti dera la Altai limadziwika m'ma TV monga malo omwe gulu latsopano la hominin lachikale, a Denisovans, linapezeka. Koma chigawochi chilinso chofunikira m'mbiri ya anthu monga njira yodutsa anthu pakati pa kumpoto kwa Siberia, Central Asia, ndi East Asia kwa zaka zikwi zambiri.
Posth ndi anzawo akuti mtundu wapadera wa majini womwe adavumbulutsa ukhoza kuyimira gwero labwino kwambiri la anthu okhudzana ndi ANE omwe adathandizira magulu a Bronze Age ochokera Kumpoto ndi Inner Asia, monga osaka osaka ku Lake Baikal, abusa ogwirizana ndi Okunevo, ndi Tarim. Basin mummies. Adavumbulutsanso makolo akale aku Northeast Asia (ANA) - omwe adafotokozedwa koyambirira kwa osaka a Neolithic ochokera ku Russia Far East - mwa munthu wina wa Neolithic Altai-Sayan wolumikizidwa ndi zikhalidwe zosiyanasiyana.
Zomwe zapezazi zikuwonetsa kufalikira kwa makolo a ANA pafupifupi makilomita 1,500 kumadzulo kuposa momwe adawonera kale. Ku Russia Far East, adazindikiranso anthu azaka 7,000 omwe ali ndi makolo ogwirizana ndi Jomon, zomwe zikuwonetsa kulumikizana ndi magulu osaka osaka ochokera ku Japan Archipelago.
Zambirizi zimagwirizananso ndi magawo angapo a majini ochokera ku North America kupita kumpoto chakum'mawa kwa Asia pazaka 5,000 zapitazi, kukafika ku Kamchatka Peninsula ndi pakati pa Siberia. Ofufuzawo akuwona kuti zomwe zapezedwa zikuwonetsa kuchuluka kwa anthu olumikizana ku North Asia kuyambira ku Holocene koyambirira.
"Zomwe zidandidabwitsa kwambiri ndizochokera kwa munthu wanthawi yofanana ndi alenje ena a Altai koma ali ndi chibadwa chosiyana kwambiri, akuwonetsa chibadwa cha anthu omwe ali ku Far East," akutero Ke Wang ku Fudan. Yunivesite, China, ndi wolemba wamkulu wa kafukufukuyu. “Chochititsa chidwi n’chakuti, munthu wa ku Nizhnetytkesken anapezedwa m’phanga limene munali zinthu zamtengo wapatali zokwirira maliro ndi zovala zachipembedzo ndi zinthu zomwe zimatanthauzidwa kuti n’zotheka kuimira chipembedzo cha shaman.”
Wang akuti zomwe zapezazi zikutanthauza kuti anthu omwe ali ndi mbiri komanso zikhalidwe zosiyanasiyana amakhala mdera lomwelo nthawi imodzi.
"Sizikudziwika ngati munthu wa ku Nizhnetytkesken adachokera kutali kapena anthu omwe adachokerako anali pafupi," akutero. "Komabe, katundu wake wam'manda amaoneka mosiyana ndi zochitika zakale zakale zomwe zimatanthawuza kuyenda kwa anthu azikhalidwe komanso chibadwa kudera la Altai."
Ma genetic ochokera ku Altai akuwonetsa kuti North Asia inali ndi magulu olumikizana kwambiri zaka 10,000 zapitazo, kudutsa mtunda wautali. "Izi zikusonyeza kuti kusamuka kwa anthu ndi kusakaniza kunali chizolowezi komanso osatinso kumadera akale osaka osaka," akutero Posth.
