Can any depiction of genetic relationships among humans allow simultaneously for similarity, diversity, ancestry, and admixture (i.e., groups that had split mixing again)? I asked this question while puzzling over the messages conveyed by diagrams from the work of Tishkoff and collaborators on genetic variation among humans in and out of Africa. In this talk I present explorations of alternative depictions of human genetic variation keeping my initial question in mind. By the end I will have prepared the ground for an assertion that the very methodology of generating and depicting human ancestry privileges a racialized view of human diversity.
This podcast examines several kinds of conceptual problems that have not been addressed by scientists and other commentators who claim, as happens every few years, that science now shows race has a biological basis (mp3 22 mins)
An Open Courseware version of a Spring 2017 graduate course in which students developed their abilities to expose ways that scientific knowledge has been shaped in contexts that are gendered, racialized, economically exploitative, and hetero-normative. The course used a Project-Based Learning format that allowed students to shape their own directions of inquiry in each project, development of skills, and collegial support. Students’ learning was guided by individualized bibliographies co-constructed with the instructors, the inquiries of the other students, and a set of tools and processes for literary analysis, inquiry, reflection, and support.

Science writer, Nicholas Wade, and philosopher Nevan Sesardic, among others have argued that Rosenberg et al’s division of human genetic diversity into reasonably distinct clusters (depicted as bands of color in their diagrams) shows that human racial divisions have a biological basis after all. Some lines of critical inquiry that I would recommend: Continue reading

Population geneticist, Richard Lewontin “found that the majority of the total genetic variation between humans (i.e., of the 0.1% of DNA that varies between individuals), 85.4%, is found within populations, 8.3% of the variation is found between populations within a ‘race’, and only 6.3% was found to account for the racial classification. Numerous later studies have confirmed his findings” (wikipedia). Critics of Lewontin, Continue reading
