ABSTRACT
DNA ancestry tests, which include genetic ancestry tests and genomic ancestry
tests, may have significant and substantial implications. Existing discussions of these
implications are framed as “ELSI” (i.e. ethical, legal, and social implications) research
according to the National Human Genome Research Institute’s lead. The commentary
widely accepted as leading authority on ELSI of DNA ancestry tests – “The Science and
Business of Genetic Ancestry Testing”1 – offers many claims as to the impacts of this
genetic technology. Yet the authors provided no factual basis to support their claims and
systematic investigations of the merits of those claims have been absent. This research
project aims to address the claims made in this seminal commentary about social and
legal implications. First, I provide an introduction to these ELSI discussions; an
introduction to the DNA ancestry testing industry by explaining the types of DNA
ancestry tests available, their scientific capabilities and limitations, and the commercial
diversity of marketing and products; an overview of the current criticisms of the DNA
ancestry tests; and a call for an anthropological approach to ELSI research. Subsequently,
I focus on the social implications of DNA ancestry tests and use blog analysis,
generalized surveys, and focused surveys to search for evidence of the social implications
frequently reported. Next, I address the legal implications raised by ELSI authorities but
never before investigated systematically. I provide background information on relevant
legal theories and discuss a conceptual method that may assist non-legal professionals
studying legal implications of genetic technologies. This eco/devo/evo conceptual
method is then applied to explore specifically claims by Bolnick and colleagues that (1)
direct-to-consumer genetic testing is the unauthorized practice of medicine; (2) DNA
ancestry testing as used by law enforcement officers is an unconstitutional “DNA
dragnet;” and (3) individuals are purchasing DNA ancestry tests to seek legal
entitlements reserved for Native Americans. Additionally, attention is given to the
popular issue of genetic privacy. Finally, some preliminary conclusions about the

PREFACE
It was July 1999. I had just finished my freshman year studying anthropology at
Penn State University and returned from an archaeological field school when I
approached Dr. Mark Shriver about my interest in working in his anthropological
genetics laboratory. I recall the excitement I felt as I sat in that unforgettable orange chair
as I listened to Mark explain his research on normal variation of common traits. I knew
right away that working in Mark’s lab was an amazing opportunity. For the next three
years I was engaged in all aspects of the research: obtaining the informed consent and
collecting anthropometric data from research participants; running PCRs and genotyping
with gels and mcSNP; preparing grant proposals and presentations; attending
conferences; and writing journal articles. These hands-on research experiences only
supplemented my formal training in biological anthropology by other brilliant scholars
(e.g. my first introductory course in biological anthropology was team-taught by leaders
of each sub-discipline – genetics by Dr. Kenneth Weiss, paleontology by Dr. Alan
Walker, and primatology by Dr. Jeffrey Kurland). The entire experience was truly life-
changing for me, a small town girl from central Pennsylvania.
In 2002 I began a graduate program in human genetics under the supervision of
Dr. Jeffrey Long at the University of Michigan. While I was there, however, the
university’s policies for undergraduate and law school admissions were facing
constitutional challenges before the Supreme Court of the United States. I always was
passionately outspoken against racial discrimination. The media attention and debates
that surrounded these two court cases, Grutter v. Bollinger and Gratz v. Bollinger, lit a
fire under me. I left my doctoral program in human genetics at the University of
