Despite the popular perception that genetic explanations of the causes of crime are new, biological determinism dates back to the birth of criminology, and the ideas of the man widely regarded as its founder, Cesare Lombroso. His 1876 work, DEGREESICriminal Man DEGREESR, drew on Darwin to propose that most lawbreakers were throwbacks to a more primitive level of human evolution--identifiable by their physical traits, such as small heads, flat noses, large ears, and the like. These born criminals could not escape their biological destiny.

The scientific appeal of these theories of criminal anthropology had a powerful and long-lasting impact on criminological theory and practice in contemporary Italy, Europe, and the Western world as a whole, and even today the stereotypes they created resonate in popular culture. But while these ideas had a wide influence, their origins were very much in a specific time and place--the political, economic, and social history of modern Italy. Gibson shows that understanding the development of Lombroso's thinking is much more complicated than merely pinning his ideas onto the left-right political spectrum; he influenced socialists and fascists, lawyers and doctors, policemen and social workers alike. In the end, she argues for a more subtle interpretation of his theories, emphasizing that Lombroso himself acknowledged the multifaceted nature of criminal behavior.

Population genomics is a rapidly emerging field that has the potential to transform our understanding of how evolutionary forces shape genomic diversity among microbes. There have already been considerable advances in understanding gene flow and spread of adaptive traits, and in linking epidemiology with evolutionary biology. The current challenge is to find unifying evolutionary principles for organisms that display a wide range of reproductive biology - from highly clonal to promiscuous - and for which the vast majority have eluded cultivation. This requires interdisciplinary approaches that incorporate novel computational tools, testing of existing and novel population genetic models, and creative new ways of linking genetic diversity to ecological factors. This pioneering book will discuss the advances made and promises of population genomics in microorganisms, outlining some of the key theoretical and practical challenges for microbial population genomics, including defining and identifying populations, genomics-based reverse ecology and building appropriate tools to understand microbes in a variety of complex environments.

This book presents a long-term study in genetic isolates of indigenous small ethnics of Dagestan, located in the North-East part of Caucasus in Russia. Dagestan is characterized by extreme cultural and linguistic differences in a small geographic area and contains 26 indigenous ethnic groups. According to archeological data these indigenous highland ethnics have been living in the same area for more than ten thousand years. Our long-term population-genetic study of Dagestan indigenous ethnic groups indicates their close relation to each other and suggests that they evolved from one common ancestral meta-population. Dagestan has an extremely high genetic diversity between ethnic populations and a low genetic diversity within them. Such genetic isolates are exceptional resources for the detection of susceptibility genes for complex diseases because of the reduction in genetic and clinical heterogeneity. The founder effect and gene drift in these primary isolates may have caused aggregation of specific haplotypes with limited numbers of pathogenic alleles and loci in some isolates relative to others. The book presents a study in four ethnically and demographically diverse genetic isolates with aggregation of schizophrenia that we ascertained within our Dagestan Genetic Heritage Research Project. The results obtained support the notion that mapping genes of any complex disease (e.g., schizophrenia) in demographically older genetic isolates may be more time and cost effective due to their high clinical and genetic homogeneity, in comparison with demographically younger isolates, especially with genetically heterogeneous outbred populations.

This is the story of a profound revolution in the way biologists explore life's history, understand its evolutionary processes, and reveal its diversity. It is about life's smallest entities, deepest diversity, and greatest cellular biomass: the microbiosphere. Jan Sapp introduces us to a new field of evolutionary biology and a new brand of molecular evolutionists who descend to the foundations of evolution on Earth to explore the origins of the genetic system and the primary life forms from which all others have emerged. In so doing, he examines-from Lamarck to the present-the means of pursuing the evolution of complexity, and of depicting the greatest differences among organisms.
The New Foundations of Evolution takes us into a world that classical evolutionists could never have imagined: a deep phylogeny based on three domains of life and multiple kingdoms, and created by mechanisms very unlike those considered by Darwin and his followers. Evolution by leaps seems to occur regularly in the microbial world where molecular evolutionists have shown the inheritance of acquired genes and genomes are major modes of evolutionary innovation.
Revisiting the history of microbiology for the first time from the perspective of evolutionary biology, Sapp shows why classical Darwinian conceptions centering on questions of the origin of species were forged without a microbial foundation, why classical microbiologists considered it impossible to know the course of evolution, and classical molecular biologists considered the evolution of the molecular genetic system to be beyond understanding. In telling this stirring story of scientific iconoclasm, this book elucidates how the new evolutionary biology arose, what methods and assumptions underpin it, and the fiery controversies that continue to shape biologists' understanding of the foundations of evolution today.

The ability of a single genome to give rise to hundreds of functionally distinct cell type programs is in itself remarkable. Pioneering studies over the past few decades have demonstrated that this plasticity is retained throughout development, a phenomenon of epigenetic programming and reprogramming that remains one of the most fascinating areas of modern biology, with major relevance to human health and disease. This book presents the basic biology involved, including key mechanistic insights into this rapidly growing field.

The difference among pluripotent stem cells, multipotent stem cells, and unipotent stem cells is pointed out. Vast therapeutic applications of the following specific stem cells in disease and tissue injury are discussed: human embryonic stem cells, human mesenchymal stem cells, germ cell-derived pluripotent stem cells, induced pluripotent stem cells, human umbilical cord blood-derived stem cells, breast tumor stem cells,and hematopoietic stem cells. Because of the potential of human embryonic stem cells to produce unlimited quantities of any human cell type, considerable focus is placed on their therapeutic potential. Because of their pluripotency, these cells have been used in various applications such as tissue engineering, regenerative medicine, pharmacological and toxicological studies, and fundamental studies of cell differentiation. The formation of embryoid bodies, which are three-dimensional aggregates of embryonic stem cells, is explained as this is the first step in cell differentiation. Such embryoid body culture has been widely used as a trigger for the in vitro differentiation of embryonic stem cells. The basic capacity of self-renewal of human embryogenic stem cells is explained. The role of TGF-beta in the propagation of human embryonic stem cells is discussed. The differentiation of human embryonic stem cells into neurons, hepatocytes, cardiomyocytes, and retinal cells is fully explained. Donor policies for hematopoietic stem cells are also explained.
