Book Description
By focusing on the cellular mechanisms that underlie ontogeny, phylogeny and regeneration of complex physiologic traits, Evolution, the Logic of Biology demonstrates the use of homeostasis, the fundamental principle of physiology and medicine, as the unifying mechanism for evolution as all of biology. The homeostasis principle can be used to understand how environmental stressors have affected physiologic mechanisms to generate condition-specific novelty through cellular mechanisms. Evolution, the Logic of Biology allows the reader to understand the vertebrate life-cycle as an intergenerational continuum in support of effective, on-going environmental adaptation. By understanding the principles of physiology from their fundamental unicellular origins, culminating in modern-day metazoans, the reader as student, researcher or practitioner will be encouraged to think in terms of the prevention of disease, rather than in the treatment of disease as the eradication of symptoms. By tracing the ontogeny and phylogeny of this and other phenotypic homologies, one can perceive and understand how complex physiologic traits have mechanistically evolved from their simpler ancestral and developmental origins as cellular structures and functions, providing a logic of biology for the first time. Evolution, the Logic of Biology will be an invaluable resource for graduate students and researchers studying evolutionary development, medicine and biology, anthropology, comparative and developmental biology, genetics and genomics, and physiology.

Book Description
Evolution is not merely a chapter in biology textbooks; rather, it is the mesh that embraces and connects every biological phenomenon; indeed, as Dobzhansky pointed out, nothing in biology could be understood without the evolutionary logic. The contents of this book highlight the importance of evolution in applied biological sciences such as agricultural, medical, environmental and the social sciences. Evolutionary science provides renewed ideas which can result in practical applications and tools that deal with current problems concerning humanity, such as disease, food production, and environmental destruction. Most of the topics in this book were discussed during the III Summit on Evolution which took place in the Galapagos Islands in June 2013, hosted by the Galapagos Institute for the Arts and Sciences and the Galapagos Science Institute, Universidad San Francisco de Quito.

Book Description
This book presents 20 selected contributions to the 18th Evolutionary Biology Meeting, which took place in September 2014 in Marseille. They are grouped under the following major themes: · Genotype to Phenotype · Genetic Mechanisms of Diversification · Evolutionary Mechanisms · Speciation and Biodiversity The aims of these annual meetings in Marseille are to bring together leading evolutionary biologists and other scientists who employ evolutionary biology concepts, e.g. for medical research, and to promote the exchange of ideas and encourage interdisciplinary collaborations. Offering an up-to-date overview of recent advances in the field of evolutionary biology, this book represents an invaluable source of information for scientists, teachers and advanced students.

Book Description
The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Book Description
How accurate is the picture of the human mind that has emerged from studies in neuroscience, psychology, and cognitive science? Anybody with an interest in how minds work - how we learn about the world and how we remember people and events - may feel dissatisfied with the answers contemporary science has to offer. Sensorimotor Life draws on current theoretical developments in the enactive approach to life and mind. It examines and expands the premises of the sciences of the human mind, while developing an alternative picture closer to people's daily experiences. Enactive ideas are applied and extended, providing a theoretically rich, naturalistic account of meaning and agency. The book includes a dynamical systems description of different types of sensorimotor regularities or sensorimotor contingencies; a dynamical interpretation of Piaget's theory of equilibration to ground the concept of sensorimotor mastery; and a theory of agency as organized networks of sensorimotor schemes, as well as its implicatons for embodied subjectivity. Written for students and researchers of cognitive science, the authors offer a fuller view of the mind, a view better attuned to the experiences of people who live, work, love, struggle, and age, thrown into a world of meaningful relations they help create. Additionally, the book is of interest to neuroscientists, psychiatrists, and philosophers of science.

Book Description
Transfer RNAs (tRNAs) are one of the classical non-coding RNAs whose lengths are approximately 70–100 bases. The secondary structure of tRNAs can be represented as the cloverleaf with 4 stems, and the three dimensional structure as an “L” shape. Historically, the basic function of tRNA as an essential component of translation was established in 1960s, i.e., each tRNA is charged with a target amino acid and these are delivered to the ribosome during protein synthesis. However, recent data suggests that the role of tRNA in cellular regulation goes beyond this paradigm. In most Archaea and Eukarya, precursor tRNAs are often interrupted by a short intron inserted strictly between the first and second nucleotide downstream of the anticodon, known as canonical nucleotide position (37/38). Recently, a number of reports describe novel aspects of tRNAs in terms of gene diversity, for example, several types of disrupted tRNA genes have been reported in the Archaea and primitive Eukarya, including multiple-intron-containing tRNA genes, split tRNA genes, and permuted tRNA genes. Our understanding of the enzymes involved in tRNA functions (e.g., aminoacyl-tRNA synthetase, tRNA splicing endonuclease, tRNA ligase) has deepened. Moreover, it is well known that tRNA possesses many types of base modifications whose enzymatic regulations remain to be fully elucidated. It was reported that impaired tRNA nuclear-cytoplasmic export links DNA damage and cell-cycle checkpoint. Furthermore, a variety of additional functions of tRNA, beyond its translation of the genetic code, have emerged rapidly. For instance, tRNA cleavage is a conserved part of the responses to a variety of stresses in eukaryotic cells. Age-associated or tissue-specific tRNA fragmentation has also been observed. Several papers suggested that some of these tRNA fragments might be involve in the cellular RNA interference (RNAi) system. These exciting data, have lead to this call for a Research Topic, that plans to revisit and summarize the molecular biology of tRNA. Beyond the topics outlined above, we have highlighted recent developments in bioinformatics tools and databases for tRNA analyses.

Book Description
In addition of proposing a model of language based on a bio-mathematical reduction within a synthesis between deduction, induction it suggests a much more important role of learning symmetry (especially iconicity) parallel to Universal Grammar. Without any theoretical megalomania, the model you will be discovering, reading and hopefully discussing hypothesizes two propositional principles with an important role of thermodynamic information : the shift from the bio-semiotic to the semiotic order along with the neural/dynamic mapping is embedded in the shift from thermodynamic laws without proposition (methodologically defined by hypothetic-probabilistic states of the ''internal observer'', Boltzmann-Bernoulli proposals and quantization) to biological and cultural consciousness (selection, combination, self-reference and symmetry etc etc)
