“…Interestingly, the population from this karst area showed the highest levels of Amerindian ancestry on the island (Via et al., ). In contrast to the early reduction in the indigenous population in Puerto Rico, the overall population underwent rapid and sustained growth to achieve the present‐day population of approximately 3.6 million, due to a combination of high fertility and relatively low mortality (Curtis & Scarano, ).…”

“…For example, a survey in 1530 recorded only 1148 Amerindians (Vazquez, ); however, the survey only recorded slaves and was unlikely to have penetrated the interior. Indeed, a relict population of Taínos appears to have survived at least until 1800, given that a small number of “indios” were recorded in the censuses of the years spanning 1777–1800 in the mountainous region of “La Indiera,” close to present‐day Maricao in the southwest portion of the island (Curtis & Scarano, ). Interestingly, the population from this karst area showed the highest levels of Amerindian ancestry on the island (Via et al., ).…”

Strong Amerindian Mitonuclear Discordance in Puerto Rican Genomes Suggests Amerindian Mitochondrial Benefit

A large discrepancy between the Amerindian contribution to the mitochondrial and nuclear genetic components of 55 Puerto Rican (PR) genomes from the 1000 Genomes Project is identified, with Amerindian mitochondrial haplotypes being highly represented (67.3%), in strong contrast to the Amerindian autosomal contribution (12.9%). I examine the potential causes behind this strong mitonuclear discordance. The Amerindian contribution to the X chromosome is 19.8%, implying assortative mating with Amerindian females during the establishment of the PR population. However, this scenario does not account for the extraordinarily high Amerindian mitochondrial contribution. Demographic simulation of simple assortative mating scenarios during establishment of the PR population indicates that the observed Amerindian mitochondrial contribution is higher than expected. The simulations show that expansion from a small founding population does not produce the observed frequencies, instead producing the frequencies expected under neutrality, with the Amerindian mitochondrial frequencies approximately twice the Amerindian autosomal proportion. In addition, multiple replicated simulations show that drift is an unlikely explanation for the elevated Amerindian mitochondrial frequency, as these are unable to produce the elevated Amerindian mitochondrial frequency observed in the PR genomic dataset, under a range of different starting conditions. I conclude that the mitonuclear discordance appears most consistent with adaptive mitochondrial benefit; however, the molecular mechanism(s) remain to be characterized before this can be confirmed and warrant further investigation. Lastly, I show potential evidence of selection on autosomes and allosomes, using admixture proportions. Interestingly, the major histocompatibility complex locus on chromosome 6 shows greatly elevated single nucleotide polymorphism density but is unaccompanied by strong admixture variance. The observations on mitonuclear discordance may affect the interpretation of apparent assortative mating in recent human admixture events, which should be treated with caution when relying only on mitochondrial haplotype frequencies.

Padrones de población e historiografía sobre la configuración socio-racial hispanoamericana del siglo XVIII

En este artículo analizo una parte de la historiografía latinoamericana que ha estudiado las relaciones entre la construcción de los censos de población, las categorías socio-raciales que contienen y la configuración social colonial del siglo XVIII, el poder y los juegos conflictivos entre las identidades adscritas y las asumidas. Me interesa mostrar la creciente problematización que ha adquirido el estudio de estos aspectos, pasando de un largo periodo de lectura ingenua de los censos y de las categorías socio-raciales, a ver como se construían en un diálogo conflictivo entre intereses del poder, perspectivas de los empa-dronadores e intereses de los empadronados. También me interesa mostrar el reciente desarrollo de una historiografía que empieza a llamar la atención sobre ciertas categorías políticas del periodo colonial tardío y como estas complejizaban lo socioracial.
