The American double continent, the last to be colonized by modern humans, is characterized by an extraordinary cultural and linguistic diversity that, in the last decades, have fostered genetic analyses. However, its genetic history and demographic dynamics are far from being fully defined. Founder events, genetic drift, and admixture, as well as selection in native populations, together with the post-contact newcomers’ genetic contributions have made their reconstruction really challenging. Nowadays, with the advent of advanced sequencing technologies and bioinformatic tools able to acquire and analyze large amounts of modern and ancient genomic data, the knowledge of the Native American gene pool is enormously increasing with the possibility of integrating (modern and ancient) autosomal information with that derived from the mitochondrial DNA and the male-specific region of the Y chromosome.
This Special Issue will collect reviews and original research findings concerning the founding migrations from Beringia/Siberia (origins of Native Americans), the subsequent internal movements (pre-contact genetic history), and the genetic admixture during and after colonial times (post-contact genetic history), as well as historical events and socio-cultural habits that might have influenced the current genomic structure (an interdisciplinary perspective). In our view, an enriched genetic picture can be depicted not only through the analysis of the bi-parental and uni-parental genetic variation in modern and ancient individuals or groups, but also by intercepting indigenous-specific markers that survived in current general populations.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Genes is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
