<prompt> Pfupisa nyaya yacho: Muchiitiko chokutanga chezvinhu zvomuzvarirwo, masayendisiti akaronga urongwa hukuru zvikurusa hwezvinhu zvomuzvarirwo zvavanhu kubva kuvanhu vamwe navamwe. Basa guru iri raisanganisira kuongorora DNA yevanhu vokuIceland vanosvika 2 636 uye kuenzanisa kuongororwa kwaiitwa DNA yevamwe vanhu 104 000. Pakati pezvakawanwa zvinokosha zvinoverengeka, mashoko acho anoratidza kuti baba vorudzi rwomunhu - tateguru vedu vechirume vokupedzisira - vakararama pakati pamakore 174 000 na321 000 akapfuura. Dzorera pasi kuti uone vhidhiyo. Muchiitiko chokutanga chezvinhu zvomuzvarirwo, masayendisiti akaronga urongwa hukuru zvikurusa hwezvinhu zvomuzvarirwo zvavanhu kubva kuvanhu vamwe navamwe. Basa guru iri raisanganisira kuongorora DNA yevanhu 2636 vokuIceland uye kuienzanisa nezvishoma zvainge zvawanikwa pane vamwe 104 000 zvairatidza kuti vanhu vakashanduka-shanduka. Masayendisiti anoona Iceland somugodhi wegoridhe wokutsvakurudza nezvezvinhu zvipenyu. Nyika yacho yakavambwa neboka duku revagari vanobva kuEurope vakasvika makore 1.100 apfuura uye yakaramba yakaparadzaniswa kwamakore ane chiuru anotevera. Nemhaka yokuti vagari vomuIceland vane misiyano mishomanene zvikuru yemagene, masayendisiti anogona kuwana misiyano yemagene iyo inowedzera bviro yechirwere zviri nyore zvikuru. Iceland inewo chinyorwa chakasimba chemadzinza, somugumisiro wezvinyorwa zvenhau zvakachengetedzwa zvakanaka. Iyi misi, yakavakirwa pakuverengwa kwenhamba dzokuchinja kwevanhu, inopesana nezvakawanwa kare zvinoti baba vavanhu vose vakararama makore anenge 340 000 akapfuura. Masayendisiti zvino anofungidzira zera rake kuva makore 239 000 okukura - musi uri pedyo zvikuru nemadzitateguru echikadzi akajairika zvikurusa orudzi rwomunhu ayo anofungidzirwa kuva akararama makore 200 000 akapfuura. Kunze kwokuziva nezvenhau yokushanduka-shanduka, masayendisiti anoti mashoko acho achaabatsira kuwanamajini akashanduka anodzivirira nenzira yomuzvarirwo boka risingawanzowaniki revanhu pazvirwere zvakati. Kusvika pari zvino, basa racho rakapa migumisiro inovimbisa ichibatsira kuziva marudzi emarudzi 20 miriyoni pakati pevanhu vokuIceland. Pakati pemisiyano iyi, masayendisiti ari paDeCode Genetics muReykjavik akatowana majini anowedzera ngozi yechirwere cheAlzheimer, chirwere chechiropa, uye chirwere chepfungwa. Basa iri kuratidzwa kwesimba rakasiyana nerimwe rokuronga zvinhu rinotipa,...  <response>: Masayendisiti akaronga urongwa hukuru zvikurusa hwemajenomu kubva kurudzi rumwe chete. Mashoko acho anoratidza zvimwe zvinokatyamadza zvinokonzerwa nemagene muvanhu vokuIceland. Data akazivisawo kuti baba vorudzi rwomunhu vakura zvikuru kupfuura zvaifungidzirwa pakutanga. Zvikamu zvisere kubva muzana zvevanhu vane majini asingashandi zvachose. Kudzidza kwakawana majini anowedzera ngozi yeAlzheimers uye chirwere chechiropa. Masayendisiti anoti mashoko acho achaabatsira kugadzira mishonga iri nani yezvirwere.
