description

Darba mērķis: analizēt Latvijas teritorijā iegūto arheoloģisko osteoloģisko materiālu, veicot senās DNS analīzi, lai novērtētu endogēnās DNS saglabātības pakāpi un paplašinātu esošās zināšanas par Daugavas un Mēmeles krastus apdzīvojušo iedzīvotāju ģenētisko izcelsmi. Tika veikta mtDNS haplogrupu sastopamības izpēte senās DNS paraugiem, gan izmantojot publicētus rezultātus, gan veicot senās DNS analīzi dzelzs laikmeta paraugiem. Dzelzs laikmetā Latvijas teritorijā konstatējamas jaunas mtDNS haplogrupas, kas sakrīt ar līdzīgi datētām arī citur Baltijas jūras reģionā. Pētījumā izmantotās metodes ir efektīvas, tomēr nelielais mtDNS haplogrupu rezultātu skaits var tikt saistīts ar zemu senās DNS saglabātību. Ar senās DNS analīžu rezultātiem ir iespējams konstatēt mtDNS haplogrupu daudzveidības palielināšanos dzelzs laikmetā Latvijas teritorijā.
