Masayendisiti akabudisa nhevedzano yakazara yeDNA ye“chitunha chakaoma muchando chakakurumbira zvikurusa chenyika” chaÖtzi “Iceman,” uyo nyanzvi dzinodavira kuti akaurawa anodokusvika makore 5, 300 apfuura, paChipiri.

Ötzi akanga awanikwa nevanofamba mumakomo eAlps pedyo nemuganhu weItaly neAustria makore 21 apfuura muna 1991, uye ava mumwe wevanodzidzwa zvakanyanya nesaenzi pamwe chete nemhosva yekare kudarika yakanyorwa pasi rose.

Ongororo pamusoro pejenome rakazara re“Iceman” yakacheneswa kwakaratidza kuti akanga ane maziso ebrown, type-O ropa, akanga asingashiviriri lactose, akanga afarirwa nehosha yemwoyo, uye akanga atapukirwa ne<em>borrelia borgdorferi, utachiona hunokonzera chirwere cheLyme uye marwadzo emajoini.

Kunyange zvazvo Ötzi akanga ave achishingaira zvikuru, uye akanga asina kufutisa, munyori anotungamirira wenzvero yokutevedzana Albert Zink neboka rake vakawana kuti murume wekare akanga ane “chimiro chokugarwa nhaka” nokuda kwearteriosclerosis kana kuti tsinga dzakaoma, kuverenga ma<em>calcium deposits akanga awana munguva yakapfuura. kubva kune cadaver scans.

“Ufakazi hwokuti chimiro chemavara okugara nhaka chakadaro chaitovapo munguva youpenyu hwaÖtzi hune fariro huru kwatiri. Hunoratidzira kuti hosha yemwoyo haisati ichitongova hosha inobatanidzwa zvikurukuru nemararamire emazuva ano. kuti zvirwere izvi zvakatanga sei, "akadaro Zink mune chirevo chakaburitswa neChipiri.

Vatsvakurudzi vekare vakawanawo kuti "Iceman" yekare yakanga ine mazino, nyora uye akadya mbudzi yemusango asati afa nemuseve wakanamatira kumusana wake.

Masayendisiti akanga afungidzira makore mana apfuura, pashure pokunyatsotevedzanisa DNA yakatorwa mumitochondria yemasero aÖtzi, kuti “Iceman” yakanga iri yevanhu vakanyangarika muEurope, pashure pokunge ivo nhevedzano ya2008 iine kuchinja kusingawaniki muvanhu vemazuva ano.

“Tinoda kuziva zvakawanda sezvinobvira nezvemamiriro ake ekurarama, nezvake uye nezvechikonzero cherufu rwake. Takaedza chaizvo kuvaka patsva nzvimbo yematsotsi nepatinogona napo,”Zink akadaro kuna Nature.

Muchidzidzo chezvino-zvino chegenome sequencing, Sink akatevedzanisa DNA kubva munyuclei yemasero akanga atorwa kubva muchidimbu chepfupa rechiuno chaÖtzi, iro raitora inenge 96% yegenome rakazara romuzvarirwo.

Zink neboka rake vakanga vawanawo kuti Ötzi akanga ane chromosome yeY ine zvinochinja zvinowanzoitika muvarume veSardinian neCorsican, uye kuti genome yake yenyukireya yakaratidza kuti hama dzake dzepedyo dzazvino uno dzaibva kuzvitsuwa zviviri izvozvo zveMediterranean.

Masayendisiti zvino anofanotaura kuti rudzi rwaÖtzi rwakanga rwambotama kubva kuMiddle East sezvo zvokurima nokupfuya mombe zvakava zvakapararira zvikuru uye zvakapararira muEurope yose isati yafa kana kuti kusangana nemamwe mapoka mune dzimwe nzvimbo, kunze kwepazvitsuwa izvozvo.

Dzimwe nyanzvi dzakabvumirana nepfungwa iyi.

"Sardinians iboka rakaonekwa nevanhu rakasiyana nevamwe vekuEurope, uye mune izvi zvingave zvinonakidza dai vakaparadzirwa zvakanyanya munguva yakapfuura," Eske Willerslev, palaeogenomicist paYunivhesiti yeCopenhagen akaudza Nature.
