This paper explores the historical and social context of population genetic research conducted in India by focusing on a study by Reich et al which aimed to reconstruct Indian population history. The paper addresses two themes. First, it considers the agendas and modes of thinking about Indian populations and the caste system on which this study appears to be based. Second, it reflects on the medical implications of this study as they were presented in Reich et al's findings. I suggest (...) that while genetic mapping of Indian populations appears to have inherited many of the problems characteristic of population genetic research conducted in the USA and globally, the specificity of this research in India involves a peculiar interplay of the postcolonial pursuit of genomic sovereignty, desire by the Indian state to become a player in the global realm of biotechnology, and age-old discourses naturalising caste and regional differences. My argument is that, although the study has offered conceptual space for a wide range of interpretations, it has a strong potential not just for naturalising caste and regional differences in India, but also for pathologising them without necessarily bringing tangible healthcare benefits in the foreseeable future.

In the 1930s, the Otomi people living north of Mexico City became a model population for addressing the problems of poverty and "backwardness" of the Indian population. Mexican physiologists working in the capital chose the Otomies not least because they lived in easy reach of their laboratories. A collecting trip could be managed in a day and samples safely handled and promptly transferred to laboratory conditions. Following the Mexican teams that were funded by the newly created Autonomous Department of Indigenous (...) Affairs, French researchers descended on the Otomies to study their metabolism, using the networks and infrastructures put in place by their local colleagues. Their investigations, aimed at establishing... (shrink)

In this special issue we explore practices of scientific inquiry into human populations in Latin America in order to generate new insights into the complex historical and sociopolitical dynamics that have made certain human groups integral to the production of scientific knowledge in and about the region. In important contributions, other scholars have shown that the science of human difference is racist and all too often has been a mediator of development ideologies. To further unpack these arguments we focus attention (...) on the complex interaction between scientists and the populations they study. We explore cases from across the fields of evolutionary biology, demography, epidemiology... (shrink)

Given their commitment to practices, science studies have bestowed considerable attention upon objects. We have the boundary object, the standardized package, the network object, the immutable mobile, the fluid object, even a fire object has entered the scene. However, these objects do not provide us with a way of understanding their historicity. They are timeless, motionless pictures rather than things that change over time, and while enacting ‘historical moments’ they do not make visible the histories they contain within them. What (...) kind of object could embody history and make that history visible? Inspired by Michel Serres, I suggest the folded object is a way to attend to the temporality and spatiality of objects. In this article I explore this new object by unravelling the history of a DNA reference sequence. I show how, ever since it was produced in the early 1980s, attempts have been made to filter race out of the sequence. That effort has failed due to what one could call ‘political noise’. Making and remaking the sequence have left traces that cannot be erased. (shrink)
