Origin, Anthropology and Genetic Relatedness of Amerindians

All First American Inhabitants are included in the Amerindians concept: the linguistic distinction with Canadian and Alaska Athabascan and southern USA Navajo and Apache as a Na Dene separated group is doubtful as well as Aleutians Islanders of Behring Strait. Mesoamericans and South American groups are also included and the most ancient human activities in America, have been detected in either California or South America (Brazil and Chile).
The Greenberg theory of America being an empty continent which was populated by three waves of people has been discarded because of facts have contracted it. The population of America was as ancient as it was in the rest of the World.
In the present issue, we aim to uncover some of the intriguing issues that have been put forward in the last years research. It covers all Amerindian anthropology topics, like origins, relatedness to other World populations and genetics. This latter issue is particularly interesting because some genetic markers isolate Amerindians from the rest of the Word, like HLA genes. It is most useful to concentrate in polymorphic markers like Y Chr, HLA and mtDNA since they more easily distinguish or separate population, in contrast to the also useful SNPs and STRs. However, whole genome use for population genetics may sometimes be useful but noise of non polymorphic sites usually obscure results and interpretantion in population genetics studies.
Linguistics, Genetics and all other Anthropology issues research on Amerindians are a wide range of topics that are intended to be included in this special issue in order to shed light on Amerndians origins and relatedness.
