ABSTRACT In the last twenty years, contributions furnished by Archeology, Physical Anthopology, Linguistics, and Genetics have drammatically subverted the study of the origins of man in America. For example, through dental pieces Physical Anthropologists have obtained specimens resistant to post-mortem alterations directly related to evolutionary changes in the populations. At the same time, the study of genetic frequencies and changing distributions of genetic markers in American indigenous populations have yielded new information on settlement patterns and migration, rasing doubts about the archeological evidence of the earliest human migrations. The aim of this article is to offer an overview of this literature and the new questions aroused by it.Las contribuciones producidas por la arqueología, la antropología física, la lingüística y la genética, en los últimos veinte años, han revolucionado el estudio de los orígenes de los habitantes de América. A partir de restos de piezas dentarias, los antropólogos físicos han podido obtener, por ejemplo, especímenes resistentes a alteraciones post-mortem que guardan una relación directa con los cambios evolutivos específicos de las poblaciones. Al mismo tiempo, el estudio de las frecuencias genéticas y las distribuciones cambiantes de las marcas genéticas en poblaciones originarias del territorio americano ha producido información nueva sobre los patrones de asentamiento y migración, poniendo en entredicho la evidencia arqueológica sobre las primeras migraciones humanas. el objetivo de este artículo es ofrecer al lector un panorama de esta literatura y de los nuevos interrogantes.

    ABSTRACT: To evaluate the number and time of the migration(s) that colonized the New World we analyzed all available sequences of the first hypervariable segment of the human mitochondrial DNA control region, including 544 Native Americans. Sequence and population trees showed that the Amerind, Na-Dene, and Eskimo are significantly closer among themselves than anyone is to Asian populations, with the exception of the Siberian Chukchi, that in some analyses are closer to Na-Dene and Eskimo. Nucleotide diversity analyses based on haplogroup A sequences suggest that Native Americans and Chukchi originated from a single migration to Beringia, probably from east Central Asia, that occurred approximately 30,000 or approximately 43,000 years ago, depending on which substitution rate is used, with 95% confidence intervals between approximately 22,000 and approximately 55,000 years ago. These results support a model for the peopling of the Americas in which Beringia played a central role, where the population that originated the Native Americans settled and expanded. Some time after the colonization of Beringia they crossed the Alberta ice-free corridor and peopled the rest of the American continent. The collapse of this ice-free corridor during a few thousand years 14,000-20,000 years ago isolated the people south of the ice-sheets, who gave rise to the Amerind, from those still in Beringia; the latter originated the Na-Dene, Eskimo, and probably the Siberian Chukchi.

    ABSTRACT: A polymorphic C-->T transition located on the human Y chromosome was found by the systematic comparative sequencing of Y-specific sequence-tagged sites by denaturing high-performance liquid chromatography. The results of genotyping representative global indigenous populations indicate that the locus is polymorphic exclusively within the Western Hemisphere. The pre-Columbian T allele occurs at > 90% frequency within the native South and Central American populations examined, while its occurrence in North America is approximately 50%. Concomitant genotyping at the polymorphic tetranucleotide microsatellite DYS19 locus revealed that the C-->T mutation displayed significant linkage disequilibrium with the 186-bp allele. The data suggest a single origin of linguistically diverse native Americans with subsequent haplotype differentiation within radiating indigenous populations as well as post-Columbian European and African gene flow. The mutation may have originated either in North America at a very early time during the expansion or before it, in the ancestral population(s) from which all Americans may have originated. The analysis of linkage of the DYS199 and the DYS19 tetranucleotide loci suggests that the C-->T mutation may have occurred around 30,000 years ago. We estimate the nucleotide diversity over 4.2 kb of the nonrecombining portion of the Y chromosome to be 0.00014. compared to autosomes, the majority of variation is due to the smaller effective population size of the Y chromosome rather than selective sweeps. There begins to emerge a pattern of pronounced geographical localization of Y-specific nucleotide substitution polymorphisms.

    ABSTRACT: The peopling of the New World has been the focus of anthropological attention since the last century. Proponents of multiple migration models have claimed that patterns of variation among extant New World populations reflect ancient, discrete migrations to the Americas during the terminal Pleistocene. Although multiple migration models appear to explain patterns of both past and present craniometric variation, this interpretation rests on a number of key assumptions that require further investigation. We examined a series of Paleoindian (n = 11) and Archaic (n = 384) crania from North and South America, and compare these early samples to a large world-wide sample of late Holocene (n = 6,742) remains to assess within- and among-group variability in early samples, and to determine how patterns of variation could be viewed as a reflection of both population history and population structure. Analyses included univariate and multivariate analysis of variance, principal component analysis, calculation of biological distances, and multivariate allocation methods. We also performed model-bound analyses of these data, including Relethford-Blangero analysis and calculation of F(ST). Our results indicate that under the assumptions of migration/founder models, the data are consistent with Paleoindians having derived from an undifferentiated Asian population that was not ancestral to modern American Indians. This view can be accommodated into existing models of multiple founders (migrations) in the New World. However, the assumptions required for such an interpretation are not realistic, and the diversity of early populations could as easily reflect population structuring processes such as genetic drift, demographic growth, and other phenomena. When the data were analyzed controlling for the effects of genetic drift (i.e., with smaller long-term effective population sizes for Paleoindians), the Paleoindian samples were no longer distinct from modern Native American populations. Other factors that need to be considered include processes involved in craniofacial change and adaptation during the past 10,000 years. Finally, patterns of variation in the North and South American Paleoindian samples are different, suggesting that the process of New World colonization is more complex than previously assumed.
