Zvidzidzo zvinoratidza kuti kusakwanisa kubvisa tsika yekuputa kunogona kuve kwakabatana neine genetic fungidziro. Masayendisiti akaverenga marara emhando iyo inozivisa mukana wekuve anofarira vanoputa fodya.
Vatori vechikamu muchidzidzo chevhi vakanga vari chiuru chevanenge chiuru cheZealandanders, vane makore akazosvika makore makumi matatu nemasere. Izvo zvakazoitika kuti avo vane mavara okuzvarwa akatakurwa mukati mawo zvake ekusvuta, vakatanga kuputa kunyange mukuyaruka, uye vachiputa mazuva ese. Uye nemakore makumi matatu nematatu vainyanya kukanganiswa nekotini uye vakaedza kanopfuura kamwe chete kuTie, asi vasina kubudirira, vanonyora pravda.ru.
Inofanira kucherechedzwa kuti genetics haina kukonzera chishuvo chekuputa kekutanga. Nekudaro, pane avo vakatovapindwa muropa nefodya, majini anokanganisa, uye akanyatsosimba - njodzi yekuve anowana vanoputa fodya mushure mekuwedzera kwekutanga nekuwedzera.
Icho vanoda kuziva kuti avo vakaputa fodya imwe chete kana maviri pazuva raive nediki genetic tsika yekuputa pane vanozvipira, vasiri kuputa zvachose. Asi vaiteyairi vairatidziridzwa kuputa fodya pane imwe kota kudarika vezera ravo vasingambe vanofarira kuve vanosvuta makore gumi nemashanu, uye ne43 muzana - kuputa muchirongwa pazuva nemakore gumi nemasere.
"Mhedzisiro yengozi yemhando inoita kunge inogumira kune vanhu vanotanga kuutsi mukuyaruka," anodaro munyori weDaniel Belsky kubva kuYunivhesiti yeDuke. "Izvi zvinoratidza kuti nikotini inokanganisa uropi hwechidiki neimwe nzira zvakasiyana."
