Book Description
The revised edition of this bestselling textbook provides latest and detailed account of vital topics in biology, namely, Cell Biology, Genetics, Molecular Biology, Evolution and Ecology . The treatment is very exhaustive as the book devotes exclusive parts to each topic, yet in a simple, lucid and concise manner. Simplified and well labelled diagrams and pictures make the subject interesting and easy to understand. It is developed for students of B.Sc. Pass and Honours courses, primarily. However, it is equally useful for students of M.Sc. Zoology, Botany and Biosciences. Aspirants of medical entrance and civil services examinations would also find the book extremely useful.

Book Description
This volume contains the papers presented at a symposium on popula tion biology sponsored by the Deutsche Forschungsgemeinschaft. It was . held at the guest house of the University of Ttibingen at Oberjoch on May 15-19, 1983. Prior to this conference a small group of European biologists had met in Berlin (June 1981) and Pavia (September 1982) to discuss re search problems on the borderline between population genetics and evolutionary ecology. From the contributions and discussions at these meetings it became evident that the unification of approaches to evolutionary problems in population genetics and evolutionary ecology has not yet been suc cessful and requires further efforts. It was the consensus that a larger symposium with international participation would be helpful to con front and discuss the different approaches to population biology in order to assess "where we are now" and "where we should be going. " As a result an organizational committee was formed (F. Christiansen, S. Jayakar, V. Loeschcke, W. Scharloo, and K. W6hrmann) to iden tify topics that seemed, at least to them, to be fruitful in tackling problems in population biology. Consequently, a number of colleagues were asked to participate in the meeting. We have divided this book into chapters corresponding to the eight topics chosen. The volume begins with the relation between genotype and phenotype and is followed by a chapter on quantitative genetics and selection in natural populations.

Book Description
At least since the 1940s neo-Darwinism has prevailed as the consensus view in the study of evolution. The mechanism of evolution in this view is natural selection leading to adaptation, working on a substrate of adapta tionally random mutations. As both the study of genetic variation in natural populations, and the study of the mathematical equations of selec tion are reckoned to a field called population genetics, population genetics came to form the core in the theory of evolution. So much so, that the fact that there is more to the theory of evolution than population genetics became somewhat obscured. The genetics of the evolutionary process, or the genetics of evolutionary change, came close to being all of evolutionary biology. In the last 10 years, this dominating position of population genetics within evolutionary biology has been challenged. In evolutionary ecology, optimization theory proved more useful than population genetics for interesting predictions, especially of life history strategies. From develop mental biology, constraints in development and the role of internal regula tion were emphasized. From paleobiology, a proposal was put forward to describe the fossil record and the evolutionary process as a series of punc tuated equilibria; thus exhorting population geneticists to give a plausible account of how such might come about. All these developments tend to obscure the central role of population genetics in evolutionary biology.
