Blackness, Indigeneity, Multiculturalism and Genomics in Brazil, Colombia and Mexico

Published online by Cambridge University Press:  15 May 2013

Abstract

Genomic research in Latin America has looked into the African, Amerindian and European ancestry of local populations. This article explores how indigeneity and blackness figure in genomic science in the light of previous and current representations of indigenous and Afro-descendent people. These categories have been cast as ‘other’ in Latin America, but they have occupied different locations in ‘structures of alterity’. I look briefly at these similarities and differences in the colonial and republican periods and in recent multiculturalist reforms. I look at the gendered sexual imagery surrounding each concept, before examining in detail how blackness and indigeneity figure in gendered ways in genomic science research on admixture and ancestry in Brazil, Colombia and Mexico. I conclude that, in the context of multiculturalism, genomics works to re-centre imaginaries of the nation around the mestizo and mixture, while casting blackness and indigeneity, in sexualised and gendered ways, as different kinds of others.

La genómica en Latinoamérica ha investigado la ‘ancestría’ africana, amerindia y europea de las poblaciones locales. Este artículo explora cómo la indigeneidad y la negritud figuran en la ciencia genómica a la luz de representaciones previas y actuales de los y las indígenas y afrodescendientes. Tales categorías han sido ubicadas como ‘los otros’ en América Latina, aunque han ocupado lugares diferentes en las ‘estructuras de alteridad’. Examino brevemente estas similitudes y diferencias en los periodos colonial y republicano y en las recientes reformas multiculturales. También exploro la imaginería generizada y sexualizada que rodea a cada concepto, antes de examinar en detalle cómo la negritud y la indigeneidad aparecen en forma generizada dentro de la investigación genómica relacionada con los mestizajes y la ancestría en Brasil, Colombia y México. Concluyo que, en el contexto del multiculturalismo, la genómica trabaja para recentrar los imaginarios de la nación alrededor del mestizaje y la mezcla, al mismo tiempo que ubica a la negritud e indigeneidad, en formas sexualizadas y generizadas, como maneras diferentes de otredad.

Pesquisas genômicas na América Latina investigam a ‘ancestralidade’ africana, ameríndia e européia das populações locais. O artigo explora como a indianidade e a negritude figuram na ciência genômica sob a ótica de representações prévias e atuais de pessoas afrodescendentes e indígenas. Estas categorias foram retratadas como ‘outras’ na América Latina, porém, têm ocupado posições diferentes nas ‘estruturas da alteridade’. Analiso brevemente essas semelhanças e diferenças durante os períodos colonial e republicano e durante reformas multiculturalistas recentes. Considero a imagética sexualizada e basada em estereótipos de gênero que envolve cada conceito, antes de examinar detalhadamente como a negritude e a indianidade figuram em formas relacionadas ao gênero em pesquisas científicas de genômica acerca da miscigenação da descendência no Brasil, Colômbia e México. Concluo que, no contexto do multiculturalismo, a genômica trabalha para mais uma vez centrar os imaginários sobre as nações em torno da mestiçagem e mistura, enquanto a negritude e a indianidade são representados de formas sexualizadas e relacionadas ao gênero, como diferentes tipos de outros.

46 Although the majority of the admixture was deemed to have occurred in the Americas, it was recognised that some European-African admixture would have occurred pre-conquest in the Iberian Peninsula. Also, while geneticists tend to focus above all on Amerindian, African and European ancestry, there is some interest (usually in medical genetics) in other genetic contributions – for example, in Japanese and Middle Eastern ancestries in Brazil.

50 See http://news.bbc.co.uk/1/hi/6284806.stm. This project explored many dimensions of Afro-Brazilian roots, but with a marked emphasis on genetics (see www.bbc.co.uk/portuguese/noticias/cluster/2007/05/070427_raizesafrobrasileiras.shtml). This reflects not only the public debates in Brazil about raced-based affirmative actions, but also the public dissemination of genetic research, such as Pena et al., ‘Retrato molecular do Brasil’.

73 The study by Rojas et al. included 15 Colombian urban populations classified as mestizo: mtDNA analysis showed an average of 6 per cent African and 83 per cent Amerindian ancestry. See Rojas et al., ‘Genetic Make Up and Structure of Colombian Populations’. The study by Wang et al. sampled ‘mestizos’ in 13 locations spread across Latin America: see Wang et al., ‘Geographic Patterns’. These data also appear in an overview by Andrés Ruiz Linares, ‘Human Genetic Variation: Americas’, in Aravinda Chakravarti (ed.), Who Are We? Human Diversity and Race from a Contemporary Genetics Perspective (forthcoming). The mtDNA analysis reported in this overview shows a greater proportion of Amerindian than African ancestry for all samples, although this is only marginally so for the sample from southern Brazil (Rio Grande do Sul). (These precise percentage measurements of ancestry are estimates and are influenced by the nature of the sample taken and the kind of genetic markers and reference populations that are used for the analysis.)
