Molecular Evolution Towards the Origin of Metazoa Book Description:

Recently, new genes and their proteins that revealed striking new insights into the early evolution of multicellular animals have been identified and characterized from members of the lowest metazoan phylum, the porifera (sponges). The unexpected result was that the sequences obtained from sponge displayed high similarity to those found in higher metazoa; in consequence, it was concluded that during the transition from protozoa to metazoa the major structural and regulatory proteins evolved only once. The data gathered are now powerful arguments to establish monophyly of metazoa; in addition, new insights on the evolutionary diversification of metazoa were obtained.

Origin of Elements in the Solar System Book Description:

Based on an American Chemical Society Symposium organized by Professors Glenn Seaborg and Oliver Manuel, this volume provides a comprehensive record of different views on this important subject at the end of the 20th century. They have assembled a blend of highly respected experimentalists and theorists from astronomy, geology, meteoritics, planetology and nuclear chemistry and physics to discuss the origin of elements in the solar system. The intent was to include all points of view and let history judge their validity.

The Origin of Music Book Description:

"The hypothesis that music had its origin in the amatory sounds made by the male to charm the female, has the support of the popular idea that the singing of birds constitutes a kind of courtship—an idea adopted by Mr. Darwin when he says that "the male pours forth his full volume of song, in rivalry with other males, for the sake of captivating the female."...

The Origin of Stars Book Description:

Where do stars come from and how do they form? These are profound questions which link the nature of our Universe to the roots of mankind. Yet, until a recent revolution in understanding, the proposed answers have been raw speculation. Now, accompanying penetrating observations, a new picture has come into prominence. This book presents the latest astounding observations and scientific ideas covering star formation, star birth and early development. It encompasses all aspects, from the dramatic stories of individual objects, to the collective influence of entire stellar systems. The very first stars to come into existence and the nurturing of planets are discussed to provide the reader with a comprehensive overview. Presenting background information with only the essential mathematics, this book will appeal to scientists wishing to expand their horizons, students seeking solid foundations, and general readers with enquiring minds.

Key Features:Presents in concise and readable form the story of star formation, and the revelations that have shaken the foundations of the subjectProvides the knowledge essential for an understanding of the construction of stars of all typesIncludes introductions and summaries that will make the subject accessible to a broad audienceKeywords:Stars;Stellar Evolution;The Universe;Clusters;Protostars;Galaxies;Starbursts;Magnetic Field;Complex Systems;Fluid DynamicsReviews:“This book has a readable style … it should be accessible to readers with a variety of scientific backgrounds, and to advanced undergraduates. It will be particularly useful as an introduction to the subject for first year research students in astrophysics. The book is recommended reading for anyone with an interest in the subject.”Professor David Williams University College London “Overall, this is a good read, and as clear a picture of the field as his target readership is likely to get at the moment. I recommend it as ancillary reading in first- and second-year courses, or as an introduction for a junior-honours course.”The Observatory Magazine

The Evo Devo Origin of the Nose Anterior Skull Base and Midface Book Description:

The phylontogenic theory proposes an original understanding of nose, sinus and midface formation and development by looking back in evolution for the first traces of the olfactory organ and then tracing its successive phyletic transformations to become part of the respiratory apparatus and finally the central point of human facial anatomy. Von Baer’s, Darwin’s, Haeckel’s, Garstang’s, Gould’s and Buss’ explorations of parallels between phylogeny and ontogeny help to trace the nose and midface story. The paradigm of existing parallels between ontogeny and phylogeny proves useful both in seeking to understand the holoprosencephalic spectrum of facial malformations (which represent radically different pathways of facial development after the life’s tape has been started to run again) and in formulating hypotheses on chordate to vertebrate evolution. The phylontogenic theory leads to new medical hypotheses on nose and sinus diseases and opens the field of evolution and development-based medicine.

The Origin of Humanness in the Biology of Love Book Description:

The central concern of this book is us human beings. The authors’ basic question is: ‘How is it that we can live in mutual care, have ethical concerns, and at the same time deny all that through the rational justification of aggression?’ The authors answer this basic question indirectly by providing a look into the fundaments of our biological constitution, concentrating on what they term emotioning, that is the flow of emotions in daily life that guides the flow of the systemic conservation of a manner of living. Maturana and Verden-Zöller claim that the fundamental emotion that gave rise to humans as sapient languaging beings was love, and that this remains our fundament even when other emotions become socially prevalent.

The Origin Of Individuals Book Description:

In the 17th century, Descartes put forth the metaphor of the machine to explain the functioning of living beings. In the 18th century, La Mettrie extended the metaphor to man. The clock was then used as the paradigm of the machine. In the 20th century, this metaphor still held but the clock was replaced by a computer. Nowadays, the organism is viewed as a robot obeying signals emanating from a computer program controlled by genetic information. This book shows that such a conception leads to contradictions not only in the theory of biology but also in its experimental research program, thereby impeding its development. The analysis of this problem is based on the most recent experimental data obtained in molecular biology as well as the history and philosophy of biology. It shows that the machine theory did not succeed in breaking with Aristotle's finalism. The book presents a new approach to biological systems based on cellular Darwinism. Genes are ruled by probabilistic mechanisms allowing cells to differentiate stochastically. Embryo development is not governed by a determinist genetic program but by natural selection occurring among cell populations inside the organism. This theory has considerable philosophical consequences. Man may be a machine but he is a random one.
