Available in PDF, EPUB and Kindle. Book excerpt: On connaît Darwin comme fondateur de la théorie de l'évolution. Ce que l'on sait moins, c'est que la grande passion de sa vie a été l'étude des orchidées dont il possédait une extraordinaire collection. Il s'est particulièrement intéressé à leur fécondation par des insectes. Sans les guêpes, y aurait-il encore des orchidées ? Ces dernières ont développé des " stratagèmes " pour attirer les guêpes mâles et les séduire. Les guêpes ne se contentent pas de transporter du pollen, elles font littéralement " jouir " les orchidées. Ces travaux viennent compléter la théorie de l'évolution par une théorie de l'" involution ". Les branches de l'arbre de l'évolution viennent se croiser, se mêler. L'orchidée ne peut pas perdurer sans ses liens avec une autre espèce. Loin d'être un cas singulier, ce pourrait être la règle : les arbres et les champignons, les humains et les milliards de bactéries qui les peuplent... Cette nouvelle biologie, initiée par Lynn Margulis, s'oppose au " néodarwinisme ", ou théorie du " gène égoïste ", pour qui la " concurrence ", et non la collaboration ou le lien, est le mécanisme de base. On sait comment cette théorie a essaimé, en particulier dans les sciences économiques, mais aussi en sociologie. La biologie de l'involution multiplie les découvertes. Les auteures poursuivent en présentant les travaux les plus récents sur le langage chimique des plantes, par exemple sur les plants de tabac... Une nouvelle biologie indispensable à l'heure du nouveau régime climatique qui exige que nous connaissions ce à quoi et par quoi nous sommes attachés.

Download or read book Darwin, un pionnier de la physiologie végétale written by Georges Bernier and published by Académie royale de Belgique. This book was released on 2013-10-28 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: De Charles Darwin, on connaît la théorie révolutionnaire de l’évolution des êtres vivants qu’il a développée dans son livre-événement de 1859 L’origine des espèces mais beaucoup ignorent ce qui a bien pu l’occuper de 1859 à 1882, année de son décès. En fait, c’est au monde végétal qu’il a consacré une part importante de cette période, en particulier à l’étude des mouvements exécutés par les organes aériens et souterrains des plantes. Darwin découvre que ces mouvements sont universels, que la plupart sont lents mais que quelques-uns sont ultra-rapides, que certains sont provoqués par un facteur de l’environnement alors que d’autres paraissent « innés », c’est-à-dire contrôlés par un mécanisme interne à la plante. Darwin ressent vite le besoin de dépasser la simple observation des phénomènes et de passer à l’expérimentation. À partir de 1873, il associe à la poursuite de ce travail son fils Francis, physiologiste de formation. La coopération entre le génie intuitif de Charles et le travail méthodique de Francis va s’avérer incroyablement fructueuse. Elle les conduit à conclure en 1880 que l’agent responsable des mouvements est une « influence » se déplaçant dans les plantes. Le professeur Sachs (Würzburg), figure de proue de la physiologie végétale de l’époque, rejette catégoriquement cette proposition. Ce rejet assombrit les dernières années de la vie de Charles. C’est pourtant les Darwin qui avaient raison. Leur idée va susciter au XXe siècle des recherches qui déboucheront en 1928 sur la découverte de la première et la plus importante hormone végétale : l’auxine. L’histoire de cette épopée scientifique prodigieuse, racontée ici, révèle que Charles Darwin, le génial naturaliste et penseur, s’est « converti » au cours des 20 dernières années de sa vie en un génial pionnier de la physiologie des plantes. L’ouvrage est préfacé par Jean Gayon, professeur à l’Université de Paris 1 – Panthéon Sorbonne et directeur de l’Institut d’histoire et de philosophie des sciences et des techniques, à Paris.

Available in PDF, EPUB and Kindle. Book excerpt: Des premières tentatives de classification à la théorie de l'évolution, l'idée émerge d'une classification naturelle qui serait le résultat de l'histoire des organismes vivants sur Terre. Ainsi, classer les organismes et rechercher des relations de parenté sont une seule et même chose. Mais comment reconstruire l'histoire du vivant ? L'émergence de nouveaux outils conceptuels à partir des années 1960 et les avancées qu'a connues la biologie moléculaire ont été à l'origine d'une véritable révolution. Cet ouvrage retrace cette passionnante histoire qui nous mène des premières tentatives de classification des espèces aux résultats les plus novateurs de ces quinze dernières années en phylogénie moléculaire.

Available in PDF, EPUB and Kindle. Book excerpt: The recent sociobiology debate has raised fundamental and previously unresolved conceptual problems. Evolutionary Instability - Logical and Material Aspects of a Unified Theory of Biosocial Evolution - offers ap- proaches for their solution. The scientific applications comprise the dynamics and evolutionary instability of hierarchically organized systems, especially systems of interacting behavioural phenotypes in animals and man. The technical apparatus is thoroughly explained in intuitive terms within the text, and illustrated by numerous familiar examples and graphical representations, supplemented by an informal summary and discussion. The analyses offer new theoretical perspectives to such diverse fields as philosophy of science, evolutionary biology, general system theory and sociology.

This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume consists of papers written by evolutionary, molecular and organismal biologists, geneticists, ecologists, behavioural ecologists, morphologists, mathematicians, theoreticians and experimentalists, in honour of Professor Eviatar (Eibi) Nevo on the occasion of his seventieth birthday. The contributors are only a small subset of Eibi's many friends, collaborators and students (not that one can distinguish these categories among Eibi's colleagues). His widespread influence and activity, both in Israel and more generally, as a leading evolutionary biologist is indicated by his many co-authors on books and papers, and by his many students integrated in teaching and research. This volume presents some of the most recent dramatic results of molecular, genomic, and organismal evolutionary processes. It represents analyses, experiments, observations, reviews, discussions and forecasts of evolutionary theory comprising both novel methods and results, reanalyzed and reviewed data sets based on comparative, experimental, and theoretical studies utilizing model organisms across phylogeny, including bacteria, fungi, plants, animals and humans. It elucidates the revolution in molecular biology that ushered in our understanding of the evolutionary process over time and space. The topics discussed include major problems of evolutionary theory concerning origins, phylogeny, relative importance of evolutionary forces, structure and function, adaptation and speciation in space and time in changing and stressful environments. A major emerging generalization is the nonrandomness of genome structure highlighting the importance of natural selection as a major organizing evolutionary force not only at the phenotypic level, but most importantly at the interlinked genotypic molecular level. The integration between the molecular and organismal levels unifies life which is subjected to the mechanism of natural selection as a major orienting evolutionary force.

Available in PDF, EPUB and Kindle. Book excerpt: Interactions between plants and animals are incredibly diverse and complex and span terrestrial, atmospheric and aquatic environments. The last decade has seen the emergence of a vast quantity of data on the subject and there is now a perceived need among both teachers and undergraduate students for a new textbook that incorporates the numerous recent advances made in the field. The book is intended for use by advanced level undergraduate and beginning graduate students, taking related courses in wider ecology degree programmes. Very few books cover this subject and those that do are out of date.
