Bereits ein Jahr, bevor Charles Darwin seine Evolutionstheorie veröffentlicht, hat Alfred Russel Wallace Evolutionsmechanismen zu Papier gebracht, die verblüffende Ähnlichkeiten mit Darwins später publizierten Überlegungen aufweisen.
Three major aspects that distinguish this book are that (1) it contains the most detailed analysis of the sexual reproduction (oogenesis, fertilization and embryonic incubation) in a particular phylum of the aquatic invertebrates (Bryozoa) ever made; this analysis is based on an exhaustive review of the literature on that topic published over the last 260 years, as well as extensive original histological, anatomical and morphological data obtained during studies of both extant and extinct species; (2) this broad analysis has made it possible to reconstruct the major patterns, stages and trends in the evolution of sexual reproduction in various bryozoan clades, showing numerous examples of parallelisms during transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic development are discussed in detail; and (3) the key evolutionary novelties acquired by Bryozoa are compared with similar innovations that have evolved in other groups of marine invertebrates, showing the general trends in the evolution of their sexual reproduction.
This volume reports the proceedings of the eleventh triennial meeting of the Chemical Signals in Vertebrates International Symposium and thus, is the 30th anniversary of the informal grouping of scientists who convene to discuss their common interests in the ways in which vertebrates use chemical signals.
Establishing a new concept of local Lyapunov exponents the author brings together two separate theories, namely Lyapunov exponents and the theory of large deviations.
The International Conference on Intelligent Computing (ICIC) was set up as an annual forum dedicated to emerging and challenging topics in the various aspects of advances in computational intelligence fields, such as artificial intelligence, machine learning, bioinformatics, and computational biology, etc.

The Rise of Chance in Evolutionary Theory: A Pompous Parade of Arithmetic explores a pivotal conceptual moment in the history of evolutionary theory: the development of its extensive reliance on a wide array of concepts of chance.
A presentation of over 700 popular orchid species in 104 genera carefully detailed with beautiful photographs and concise descriptions of plants, their distribution and habitats by a well-known author and photographer.
Advances in fossil studies relating to the origin of Homo sapiens have strengthened the hypothesis that our direct ancestors originated on the African continent.
Primate Societies is a synthesis of the most current information on primate socioecology and its theoretical and empirical significance, spanning the disciplines of behavioral biology, ecology, anthropology, and psychology.
This book discusses the hypothesis that the primate pulvinar contains an original scaffold which is derived from cytoarchitectural markers and specific protein distributions.
A savory account of how the pursuit of delicious foods shaped human evolutionNature, it has been said, invites us to eat by appetite and rewards by flavor.
THE EVOLUTIONARY STRATEGIES THAT SHAPE ECOSYSTEMS In 1837 a young Charles Darwin took his notebook, wrote I think , and then sketched a rudimentary, stick-like tree.
Ever wondered why primroses have three sorts of flowers; or about pesticide resistance in rats and mice, mosquitoes and green-fly; antibiotic resistance in disease organisms - all are examples of genetical adjustment, explained in this book.
An important look at a groundbreaking forty-year study of Darwin's finchesRenowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galapagos finches first made famous by Charles Darwin.
Extreme Environments: Mechanisms of Microbial Adaptation is a collection of papers presented at the symposium on Extreme Environments: Mechanisms of Microbial Adaptation, held at Ames Research Center, Moffett Field, California in June 1974.
The second volume of "e;Adaptation and Evolution in Marine Environments - The Impacts of Global Change on Biodiversity"e; from the series "e;From Pole to Pole"e; integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea.
How our stone-age brains made modern society, and why it matters for relationships between men and womenAs countless love songs, movies, and self-help books attest, men and women have long sought different things.
This book is an exploration of the integration-differentiation dynamics that result in a drive, or impulse, toward human sociality, arguing that our need to connect with other people is as fundamental as our need for food and shelter.
The book is composed of eight chapters, each of which are organised as walks around the Tewkesbury (UK) countryside, which move from the specific to increasingly broader ideas.
The topics of style and function within evolutionary archaeology have been the subject of great debate in the field of archaeology in general over the past two decades.
This book provides cutting-edge studies and technologies using small fishes, including zebrafish, medaka, and other fishes as new model animals for molecular biology, developmental biology, and medicine.
The concept of altruism, or disinterested concern for another's welfare, has been discussed by everyone from theologians to psychologists to biologists.
In the grand sweep of evolution, the origin of radically new kinds of organisms in the fossil record is the result of a relatively simple process: natural selection marching through the ages.
Since the first edition of this book published in 2005, there has been an immense amount of new and fascinating work on the history, ecology, and evolution of the Mediterranean flora.
The extent to which human activity has influenced species extinctions during the recent prehistoric past remains controversial due to other factors such as climatic fluctuations and a general lack of data.
The Darwinian theory of evolution is itself evolving and this book presents the details of the core of modern Darwinism and its latest developmental directions.
A dazzling tour of evolution in action that sheds light on one of the greatest debates in scienceThe natural world is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times.
Extrait : "Quand on compare les individus appartenant à une même variété ou à une même sous-variété de nos plantes cultivées depuis le plus longtemps et de nos animaux domestiques les plus anciens, on remarque tout d'abord qu'ils diffèrent ordinairement plus les uns des autres que les individus appartenant à une espèce ou à une variété quelconque à l'état de nature.
