Such a time scale can be used to attribute relative ages to isolated fossil-bearing samples. From a practical point of view, the method described in this book will particularly interest paleontologists and geologists who must construct zonations and establish correlations on the basis of bio- stratigraphic data that are both plentiful and apparently contra- dictory. It is well known that the difficulties involved in constructing bio- chronologic scales are largely due to the discontinuous nature of the fossil record. We know that the relationships between the first ap- pearances (or disappearances) of different fossil species are rarely constant in stratigraphic sections that are distant from each other. It if often extremely difficult to discover datums or sets of species that are useful in making significant biochronologic correlations on a large scale. The theoretical model explained here (known as the Unitary As- sociation Method) provides clear solutions to most of these problems. That method is purely deterministic, as opposed to statistical and probabilistic analytical techniques producing average ranges. We demonstrate in Chapter 15 why most of these techniques produce results which are usually not compatible with the original biostrati- graphic observations (i.e., the taxonomic contents of the studied sam- ples are not reproduced in the outputs).","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52404297662737,"sku":"NLS9783540539377","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":52932500783377,"sku":"NIN9783540539377","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783540539377.jpg?v=1789469834"},{"product_id":"morphogenesis-environmental-stress-and-reverse-evolution-book-jean-guex-9783030472818","title":"Morphogenesis, Environmental Stress and Reverse Evolution","description":"\u003cp\u003eIt is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution.\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eCapacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of ‘reverse evolution’ by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.\u003cbr\u003e\u003c\/p\u003e","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52596794589457,"sku":"NLS9783030472818","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783030472818.jpg?v=1786791409"},{"product_id":"retrograde-evolution-during-major-extinction-crises-book-jean-guex-9783319279169","title":"Retrograde Evolution During Major Extinction Crises","description":"This book is the first of its kind, providing in-depth analysis of the retrograde evolution occurring during major extinction periods.
