Paleogenetika sa zaober\u00e1 \u0161t\u00fadiom DNA zachovanej v archeologick\u00fdch a paleontologick\u00fdch n\u00e1lezoch.V\u010faka pokroku v technol\u00f3gii sekvenovania DNA sme z\u00edskali inform\u00e1cie, ktor\u00e9 by pred nieko\u013ek\u00fdmi desa\u0165ro\u010diami boli nepredstavite\u013en\u00e9.

DNA starobyl\u00fdch \u013eud\u00ed n\u00e1m ukazuje, ako na\u0161i predkovia migrovali z Afriky a postupne os\u00edd\u013eovali v\u0161etky kontinenty.
