Homology Effects offers contributions from an international panel of researchers whose aim has been both to introduce newcomers to the field of homology effects, and to bring colleagues up to date. Topic coverage includes dosage compensation, X-inactivation, imprinting, paramutation, homology-dependent gene silencing, transvection, pairing-sensitive silencing, nuclear organization of chromosomes, DNA repair, quelling, RIP, RNAi and antisense biology, homology effects in ciliates, prion biology, and a discourse on the evolution of gene duplications. Advances in Genetics presents an eclectic mix of articles of use to all human and molecular geneticists. They are written and edited by recognized leaders in the field and make this an essential series of books for anyone in the genetics field. - Homology, the examination of similarity due to shared common ancestry, encompasses a fascinating class of phenomena in mammals, plants, insects, ciliates, nematodes, fungi, and bacteria. Homology effects concern processes that recognize homology at the level of DNA and/or RNA, as well as at the level of protein. Their collective history begins at the turn of the century and includes some of the most puzzling and extraordinary observations in biology. The volume covers phenomena that have often been considered unusual, exceptional to the rule, and "out of the ordinary" and, therefore, not for general study. However, it is now becoming clear that taken together, these phenomena represent a class of regulatory mechanisms that are widespread, as well as exceptionally powerful.

The application of homology varies depending on the data being examined. This volume represents a state-of-the-art treatment of the different applications of this unifying concept. Chapters deal with homology on all levels, from molecules to behavior, and are authored by leading contributors to systematics, natural history, and evolutionary, developmental, and comparative biology. This paperback reprint of the original hardbound edition continues to commemorate the 150th anniversary of Sir Richard Owen's seminal paper distinguishing homology from analogy. - Commemoration of the 150th anniversary of Sir Richard Owen's seminal paper distinguishing homology from analogy - Contributors who are renowned leaders in comparative biology - Coverage that is both comprehensive and interdisciplinary

This introduction to some basic ideas in algebraic topology is devoted to the foundations and applications of homology theory. After the essentials of singular homology and some important applications are given, successive topics covered include attaching spaces, finite CW complexes, cohomology products, manifolds, Poincare duality, and fixed point theory. This second edition includes a chapter on covering spaces and many new exercises.

'Homology' as a concept became increasingly elusive during the course of the 20th century. The central debates and controversies concern both fundamental definitions and the nature of the criteria by which homology is judged. Attempts to move away from comparative morphology to ideas based on developmental pathways have tended to founder on the fact that developmental pathways evolve and that similar cells or tissues or structures in animals will often have different developmental origins. The use of information about conserved molecules in seemingly conserved developmental processes has also proven controversial. In molecular biology, the use of the term 'homology' has given rise to more debate, although here the issue seems to involve primarily the criteria for assessing whether parts of genes are the same because of shared descent or for other reasons. The contributions to the book explore these topics systematically. There are chapters on the historical development of the concept of homology and its use in population studies. Other chapters deal with issues of homology in morphological and developmental studies, in behavioural studies, and especially in studies at the level of molecular genetics.

Knot theory is a classical area of low-dimensional topology, directly connected with the theory of three-manifolds and smooth four-manifold topology. In recent years, the subject has undergone transformative changes thanks to its connections with a number of other mathematical disciplines, including gauge theory; representation theory and categorification; contact geometry; and the theory of pseudo-holomorphic curves. Starting from the combinatorial point of view on knots using their grid diagrams, this book serves as an introduction to knot theory, specifically as it relates to some of the above developments. After a brief overview of the background material in the subject, the book gives a self-contained treatment of knot Floer homology from the point of view of grid diagrams. Applications include computations of the unknotting number and slice genus of torus knots (asked first in the 1960s and settled in the 1990s), and tools to study variants of knot theory in the presence of a contact structure. Additional topics are presented to prepare readers for further study in holomorphic methods in low-dimensional topology, especially Heegaard Floer homology. The book could serve as a textbook for an advanced undergraduate or part of a graduate course in knot theory. Standard background material is sketched in the text and the appendices.

A major synthesis of homology, written by a top researcher in the field Homology—a similar trait shared by different species and derived from common ancestry, such as a seal's fin and a bird’s wing—is one of the most fundamental yet challenging concepts in evolutionary biology. This groundbreaking book provides the first mechanistically based theory of what homology is and how it arises in evolution. Günter Wagner, one of the preeminent researchers in the field, argues that homology, or character identity, can be explained through the historical continuity of character identity networks—that is, the gene regulatory networks that enable differential gene expression. He shows how character identity is independent of the form and function of the character itself because the same network can activate different effector genes and thus control the development of different shapes, sizes, and qualities of the character. Demonstrating how this theoretical model can provide a foundation for understanding the evolutionary origin of novel characters, Wagner applies it to the origin and evolution of specific systems, such as cell types; skin, hair, and feathers; limbs and digits; and flowers. The first major synthesis of homology to be published in decades, Homology, Genes, and Evolutionary Innovation reveals how a mechanistically based theory can serve as a unifying concept for any branch of science concerned with the structure and development of organisms, and how it can help explain major transitions in evolution and broad patterns of biological diversity.

IAU Symposium 268 presents an overview of the most recent observational and theoretical research on the formation and evolution of light elements in the Universe: H, He, Li, Be, B, and their isotopes. Astrophysicists from a variety of subfields discuss recent developments that will improve our understanding of the light elements and provide important clues to stellar and galactic evolution, Big Bang nucleosynthesis, and cosmology. Striking observational progress has been achieved recently through the advent of next generation ground- and space-based telescopes, such as the cosmic microwave background experiments that allow the accurate determination of the baryon density of the Universe. New theoretical breakthroughs in describing stellar interiors and the chemical evolution of complex systems and the remaining challenges in this field are also addressed. This critical review is a useful resource for all those interested in the chemical evolution of the Universe.
