Annotation In its examination of the processes of ethnogenesis -- the formation of ethnic groups -- Ruins of Identity offers an approach to ethnicity that differs fundamentally from that found in most Japanese scholarship and popular discourse.

The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?

This iconoclastic work on the prehistory of Japan and of South East Asia challenges entrenched views on the origins of Japanese society and identity. The social changes that took place in Japan in the time-period when the Jomon culture was replaced by the Yayoi culture were of exceptional magnitude, going far beyond those of the so-called Neolithic Revolution in other parts of the world. They included not only a new way of life based on wet-rice agriculture but also the introduction of metalworking in both bronze and iron, and furthermore a new architecture functionally and ritually linked to rice cultivation, a new religion, and a hierarchical society characterized by a belief in the divinity of the ruler. Because of its immense and enduring impact the Yayoi period has generally been seen as the very foundation of Japanese civilization and identity. In contrast to the common assumption that all the Yayoi innovations came from China and Korea, this work combines exciting new scientific evidence from such different fields as rice genetics, DNA and historical linguistics to show that the major elements of Yayoi civilization actually came, not from the north, but from the south.

This book introduces the achievements of dental anthropology research in Japan to the people in the world. It starts with the tooth morphology of the people in the Paleolithic Period about 20,000 years ago. Then it goes through Jomon Age and Yayoi Age when the admixture of the people happened. Here the difference of the tooth shape between those two human groups is emphasized. After these ages, Japanese teeth were not the same from age to age influenced by the environment. In the current age of Japan, topics such as third molar agenesis, change of eruption time of the first permanent teeth, mandibular torus, and high canine are discussed. These abnormal conditions in Japan also reflect the characteristic features of Japanese history and culture.

Embodying Culture is an ethnographically grounded exploration of pregnancy in two different cultures—Japan and Israel—both of which medicalize pregnancy. Tsipy Ivry focuses on "low-risk" or "normal" pregnancies, using cultural comparison to explore the complex relations among ethnic ideas about procreation, local reproductive politics, medical models of pregnancy care, and local modes of maternal agency. The ethnography pieces together the voices of pregnant Japanese and Israeli women, their doctors, their partners, the literature they read, and depicts various clinical encounters such as ultrasound scans, explanatory classes for amniocentesis, birthing classes, and special pregnancy events. The emergent pictures suggest that athough experiences of pregnancy in Japan and Israel differ, pregnancy in both cultures is an energy-consuming project of meaning-making— suggesting that the sense of biomedical technologies are not only in the technologies themselves but are assigned by those who practice and experience them.
