‘Developmental biology’ is widely understood as processes, which mainly concern embryonic animal development and differentiation of cells and tissue. It is also often defined as the timeline for the evolutionary developmental biology of eukaryotic multicellular higher organisms, i.e., plants and animals. The development of prokaryotes and lower eukaryotes in contrary has been neglected for a long time, which was the motivation for publishing this book. This book highlights one of Darwin's most important findings: Evolution is a creative, but not a conscious process. It also illustrates that this concept does not only apply to multicellular higher organisms, but affects every form of life. The reader shall find complex biochemical and genetic pathways of bacteria, yeasts or protozoa, comparable to those exhibited by plants or animals. The molecular mechanisms of dramatic genome rearrangements, recombination and horizontal gene transfer that are responsible for evolutionary adaptations are discussed. Additionally, the book covers bacteria of the genera Myxobacteriales and Caulobacterales, which are able to develop tissue-like cellular organization. The morphogenesis of entomopathogenic fungi and the endosymbiont theory are also addressed. The book is a useful introduction to the field for junior scientists, interested in bacteriology, protistology and fungal development. It is also an interesting read for advanced scientists, giving them a broader view of the field beyond their area of specialization.

The purpose of this book is to show the essential and indispensable role of prokaryotes in the evolution of aliving world. The evolutionary success of prokaryotes is explained together with their role in the evolution of the geosphere, the biosphere and its functioning, as well as their ability to colonize all biotopes, including the most extreme ones. We consider that all past and present living beings emerged from prokaryotes and have interacted with them. Forces and mechanisms presented in the various theories of evolution apply to prokaryotes. The major stages of their evolution and biodiversity are also described. Finally, it is emphasized that prokaryotes are living organisms that provide indisputable evidence of evolutionary processes. Many examples of ongoing evolution in prokaryotes, observable at the human scale, are provided.

Reed B. Wic1mer Section on Genetics of Simple Eukaryotes Laboratory of Biochemical Pharmacology National Institute of Arthritis, Diabetes, and Digestive and Kidney Diseases Bethesda, Maryland 20892 While most genes are chromosomal, the nonchromosomal genes have played a disproportionate role in molecular biology, in part because of their easy accessibility and in part because they represent the most mobile portion of a cell's genome. This is particularly evident in prokaryotes, where plas­ mids and phages have been the central objects of study. The lower eukaryotes, including fungi and yeasts, protozoa, slime molds, algae, and other single-celled nucleated species, have long had an important role in genetic research. They have recently gained dramatic popularity with the development of transformation methods for Saccharomy­ ~, Neurospora, Schizosaccharomyces, Dictyostelium, and others of this group. The realization that Saccharomyces has oncogenes, RNA tumor virus­ es, estrogens, a polypeptide sex hormone with close homology to human lactate dehydrogenase, intervening sequences, and all the mitotic, mito­ chondrial, and other structures typical of so-called "higher" eukaryotic organisms has confirmed the use of such organisms as model systems. Their use in biotechnology also shows great promise.

'The mind unlearns with difficulty what has long been impressed upon it. ' Seneca Reductionism, is, without question, the most successful analytical approach available to the experimental scientist. With the advent of techniques for cloning and sequencing DNA, and the development of a variety of molecular probes for localizing macromolecules in cells and tissues, the biologist now has available the most powerful reductionist tools ever invented. The application of these new technologies has led to a veritable explosion of facts regarding the types and organization of nucleotide sequences present in the genomes of eukaryotes. These data offer a level of precision and predictability which is unparalleled in biology. Recombinant DNA techniques were initially developed to gather information about the structure and organization of the DNA sequences within a genome. The power and potential of these techniques, however, extend far beyond simple data collection of this kind. In an attempt to use the new technology as a basis for analyzing development and evolution, attention was first focused on the topic of gene regulation, an approach that had proven so successful in prokaryotes. It is now clear that this has not been an adequate approach. Lewin (1984) has quoted Brenner as stating 'at the beginning it was said that the answer to the understanding of development was going to come from a knowledge of the molecular mechanisms of gene control. I doubt whether anyone believes this any more.

Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.
