Book excerpt: Dziebel has doctorates in both history and anthropology and is currently both advisor to the Great Russian Encyclopedia and senior anthropologist at Crispin Porter + Bogusky advertising agency. His extremely dense work is actually three books in one. The first is a history of kinship studies from the early 19th century to the present. The second is a comparative study of kinship terminology among non-Indo-European languages, for which he has also prepared a data base published on the internet. The third section, highly controversial, as he admits, uses anthropology, mitochondrial studies and linguistics to suggest that the "out of Africa" model of human origins may be in error and that the first humans actually came from the Americas and spread from there to the rest of the world.
