In , the geneticist Luigi Luca Cavalli-Sforza was teaching in Parma when a student--a priest named Antonio Moroni--told him about rich church records of demography and marriages between relatives. After convincing the Church to open its records, Cavalli-Sforza, Moroni, and Gianna Zei embarked on a landmark study that would last fifty years and cover all of Italy. This book assembles and analyzes the team's research for the first time. Using blood testing as well as church records, the team investigated the frequency of consanguineous marriages and its use for estimating inbreeding and studying the relations between inbreeding and drift. They tested the importance of random genetic drift by studying population structure through demography of the last three centuries, using it to predict the spatial variation of frequencies of genetic markers. The authors find that drift-related genetic variation, including its stabilization by migration, is best predicted by computer simulation.

Recent studies have detailed a remarkable degree of genetic and linguistic diversity in Northern Island Melanesia. Here we utilize that diversity to examine two models of genetic and linguistic coevolution. The first model predicts that genetic and linguistic correspondences formed following population splits and isolation at the time of early range expansions into the region. The second is analogous to the genetic model of isolation by distance, and it predicts that genetic and linguistic correspondences formed through continuing genetic and linguistic exchange between neighboring populations. We tested the predictions of the two models by comparing observed and simulated patterns of genetic variation, genetic and linguistic trees, and matrices of genetic, linguistic, and geographic distances. The data consist of autosomal microsatellites and structural linguistic features collected from 33 Northern Island Melanesian populations.

Historians relying on written records can tell us nothing about the It is the study of genetic variation, backed up by language and archaeology, which provides concrete evidence aboutthe spread of farming, the movements of peoples across the globe, the precise links between races - and the sheer unscientific absurdity of racism. Genes, Peoples and Languages offers an astonishing investigation into the past , years of human history and a rare, firsthand account of some of the most significant and gripping scientific work of recent years. Cavalli-Sforza is one of the great founding fathers of archaeogenetics, and in this book he maps out some of its grand themes. Genes, Peoples, and Languages. Three hundred years ago, pirates ruled the oceans.


Cavalli-Sforza and others have answered this question—anticipated by Darwin—​with a decisive yes. Genes, Peoples, and Languages comprises five lectures.


Luigi Luca Cavalli-Sforza

Luigi Luca Cavalli-Sforza was among the first to ask whether the genes of modern populations contain a historical record of the human species. Cavalli-Sforza and others have answered this question—anticipated by Darwin—with a decisive yes. Genes, Peoples, and Languages comprises five lectures that serve as a summation of the author's work over several decades, the goal of which has been nothing less than tracking the past hundred thousand years of human evolution. Cavalli-Sforza raises questions that have serious political, social, and scientific import: When and where did we evolve? How have human societies spread across the continents?

TI,is project is an immense intellectual achievement, and Genes, Peoples and Languages. Genes, Peoples and Languages is, among other things, an intellectual biography - a complex portrait of. In this short, lucid book he describes the insights that have been gained about the way our species evolved and spread, leading to.

He was a population geneticist who taught at the University of Parma , the University of Pavia and then at Stanford University. In , he was appointed to a research post at the Department of Genetics, Cambridge University by the statistician and evolutionary biologist Ronald A. Fisher in the field of E.
