Contribution of Genetics in the Recent Human Evolution Study: Knowledge, Problems and Future Prospects

The study of human evolution involves several scientific disciplines particularly paleontology, archeology and genetics. The research in the latter has provided new insights into the evolutionary relationships of human populations leading to an improved understanding of their origin and their migration across the globe. In fact, mutations on genes and non-coding DNA sequences occurred since our deep evolutionary past represent precious traces the analyses of which permit to refer the past from present. The research development of human evolutionary genetic studies has been passed through two principal stages. In this paper I present briefly the most important general conclusions obtained during these two stages. Besides, I present and discuss emerged problems concerning particularly the persistence of some problematic considerations and confusions and vagueness related to some concepts. I believe that it is time to uproot all problematic considerations and resolve all other problems that have curbed the progression of research in this topic and to move on new more objective and more empirical research tracks.
