Integrating Different Biological Evidence Around Some Microevolutionary Processes: Bottlenecks and Asian-American Arctic Gene Flow in the New World Settlement

摘要: Excepting some specific efforts, most of the mainstream debate around Americas’ settlement has been directed by specialists dealing with partial evidence. Thus, discussions have confined to particular academic and scientific environments limited interchange among archeologists, physical anthropologists, linguists, geneticists, geologists, paleontologists, so on. As a consequence, integrative views about process that is complex definition scarce driven confrontation rather than search for common results. Still, an increasing number are attempting integrate different types data. In our view, proper way do this focus discussion evolutionary or cultural processes putative patterns such could generated in data, which turn, depend on nature way, analyses conclusions can be interpreted as “model-bound” purely inferential. paper, we first provide brief summary main differences two sources biological information—genetics craniofacial size shape—along genetic variation provide. Furthermore, exemplify above-mentioned notion discussing their hypothetical impact data: influence bottlenecks during early dispersal zone gene flow Asian American Circum-Arctic populations.
