Ribeiro's typology, genomes, and Spanish colonialism, as viewed from Gran Canaria and Colombia

Abstract

Four biallelic and six multiallelic Y-chromosome polymorphisms were investigated in 59 Gran Canarian, 60 North African Berber and 46 Spanish subjects. These new data were merged with equivalent literature information to obtain the parental Y-chrosomomal contribution in Gran Canarians, Colombians, and Venezuelans. The results were then compared, for Gran Canarians and Colombians, to those derived from autosomal and mtDNA. In both groups, the Spanish Y-chromosome contribution was much more marked than that estimated using mtDNA. This analysis showed a usual trend in the Spanish Colonial history, characterized by a demographic collapse of the aboriginal population, but with considerable introgression of genes through native women. In accordance to D. Ribeiro's typology for peoples subjected to Colonialism, the Y-chromosomes of these admixed populations are classified as transplanted, their mtDNA as witness, and their autosome sets as new.

Natural selection and molecular evolution in primatePAX9gene, a major determinant of tooth development

“…Appropriate informed consent was obtained from all of them. Additional information about these human samples can be obtained in previous reports (59)(60)(61)(62). Six samples from four species of NW primates, including three S. sciureus (squirrel monkey), one S. boliviensis (Bolivian squirrel monkey), one A. infulatus (night monkey), and one C. jacchus (common marmoset) as well as one sample of the Great Apes (G. gorilla), were also analyzed for exon 3.…”

Interethnic variability and admixture in Latin America - social implications

“…This terminology is also adequate, because it indicates the unique possibility of rescuing part of the lost history of extinct aboriginal groups through their permanence in the women of the admixed populations. The nuclear genome, however, due to considerable reshuffling, would be entirely new (Bortolini et al 2004). Cerda-Flores et al (2002a, b) recently reviewed the studies on interethnic admixture in México, providing new estimates of the accumulated proportion of parental groups using D1S80, HLA-DQA1, and 13 STRPs for the northeastern region of that country.…”

Niger‐Congo speaking populations and the formation of the Brazilian gene pool: mtDNA and Y‐chromosome data

“…However, the presence of the E3b2 chromosome in Brazil is most likely related to Iberian men, since typical Berber Y-chromosomes have been reported in Portuguese/Spanish populations. The existence of a common genetic background between Berbers and Iberians probably reflects the genetic impact of the Islamic occupation of the Iberian Peninsula for 7 centuries (Carvalho- Silva et al, 2001;Lucotte et al, 2001;Bortolini et al, 2004b;Cruciani et al, 2004;Semino et al, 2004;Gonçalves et al, 2005).…”
