Abstract
Glavni cilj diplomskega dela je predstaviti nova dognanja človeške evolucije in nova dognanja na področju paleogenetike. Človeške evolucije se ne da predstaviti linearno, temveč kot grm, saj je v njej ogromno vrst in rodov, ki so se izkazali za slepe veje in na koncu so izumrle prav vse, razen ene – nas. Genetika in paleogenetika nam bosta v prihodnosti znali pojasniti vzrok za našo uspešnost in pomagala pri premagovanju bolezni in telesnih okvar. Paleogenetske raziskave lahko dobro dopolnjujejo arheološke interpretacije, zlasti pri demografskih in epidemioloških raziskavah populacij v preteklosti.Danes imamo od izumrlih homininov (izraz za družino v človeški liniji od razcepa človeka in človeku podobnih opic), zaenkrat na voljo genetski zapis neandertalcev in denisovcev. Vemo tudi, da sta se obe podvrsti križali druga z drugo in modernim človekom. Diplomsko delo se prav tako osredotoči na posledice teh križanj, kako se geni, ki smo jih dobili od ostalih človeških (pod)vrst danes izražajo in nam pomagajo oziroma otežujejo pri vsakodnevnem življenju. Pri tovrstnih interpretacijah posledic moramo biti pozorni tudi na okolje, v katerem živimo danes, ki je zelo drugačno kot pred 50.000 leti, ko naj bi prišlo do epizod križanja.

Title:Origin and genetic heritage of Homo sapiens
Abstract:
The thesis focuses on new aspects of human evolution and paleogenetic. Human evolution cannot be presented in a line, but more like a bush with a lot of intertwining and dead branches. (Paleo)genetics can help us explain our origin and battle illnesses and deformities in the near future. Paleogenetics will also be able to perfect archaeological interpretations and demographic or epidemiological research of past populations.Today we only have two complete genomes of extinct hominins: Neanderthal and Denisovan. We also know, that these two subspecies interbred with each other and with anatomically modern humans. The thesis also focuses on the consequences of interbreeding between Neanderthals, Dneisovans and modern humans, and how the genes are expressing today. When interpreting these consequences we have to keep in mind, that today’s environment has drastically changed over the course of 50.000 years, when interbreeding occurred.

Keywords:Key words: genetics, human evolution, neanderthal, denisovan, paleogenetics
