A new view for studying and understanding biological evolution emerges when the concepts of phylogenetic systematics and exaptation are combined. A new definition of macroevolution is created. Preadaptation is shown to be a null concept and its comparison with exaptation is shown to be inappropriate. This book criticizes the prevailing view, the adaptationist, microevolutionary outlook, which considers adaptation as being the exclusive or main evolutionary process responsible for vertebrates having occupied the terrestrial environment. The authors argue that the macroevolutionary processes are significantly more important to explain an improbable evolutionary event. Their research shows that macroevolutionary processes are the dominant factors involved in the origin of terrestriality. This book is a revised and expanded English translation from the original Portuguese edition Peixes conquistam a terra firme: nova abordagem para um evento acidental único (Editora Baraúna, 2017).
This book is the third volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. It is devoted to the remaining Sedentaria and the first branches of Errantia. These sedentary polychaetes are Terebellida and Arenicolida, all of which are tube-dwelling and deposit feeders. The tubes may be simple burrows stabilized by mucus or the tubes are highly sophisticated often really aesthetic structures build-up of sediment grains glued together by their secretion. Although the former possess anterior appendages used for collecting food particles, these are likely not ...
More than the usual academic textbook, the present volume presents sociology as terrain that one can virtually traverse and experience. Each version of the sociological imagination captured by the chapter essays takes the readers to the realm of the taken-for-granted (such as zoological collections, food, education, entrepreneurship, religious participation, etc.) and the extraordinary (the likes of organizational fraud, climate change, labour relations, multiple modernities, etc.) - altogether presumed to be problematic and yet possible. Using the sociological perspective as the frame of reference, the readers are invited to interrogate the realities and trends which their social worlds relentlessly create for them, allowing them in return, to discover their unique locations in their cultures' social map.
The ocean was the origin of life on earth billions of years ago and it is vital for the future of humanity. It is vast, deep, harsh and somehow “rebellious” to uncover its secrets and hence, there is much that is unexplored and misunderstood. Scientists need to study the ocean to better understand its functioning and properties, as well as how they shape our environment and impact us. For example, do you know what the role of the ocean is on weather and climate? There still remains so much to explore in ocean biodiversity and the diverse resources that can be found (for example, fish stocks, bio-molecules, and also minerals, oil, and gas). How can we make sure that our use of these resou...
Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and recommendations governing phylogenetic nomenclature. Nearly 300 clades - lineages of organisms - are defined by reference to hypotheses of phylogenetic history rather than by taxonomic ranks and types. This volume will document the Real World uses of PhyloCode and will govern and apply to the names of clades, while species names will still be governed by traditional codes. Key Features Provides clear regulations for implementing new guidelines for naming lineages of organisms incorporates expressly evolutionary and phylogenetic principles Works with existing codes of nomenclature Eliminates the reliance on rank-based classification in favor of phylogenetic relationships Related Titles: Rieppel, O. Phylogenetic Systematics: Haeckel to Hennig (ISBN 978-1-4987-5488-0) Cantino, P. D. and de Queiroz, K. International Code of Phylogenetic Nomenclature (PhyloCode) (ISBN 978-1-138-33282-9).
O enigma da conquista da terra firme pelos animais que possuem coluna vertebral, como nós, humanos, fascina não apenas paleontólogos e biólogos profissionais, mas também as pessoas de modo geral. Desde quando Darwin esclareceu o mecanismo de origem das espécies por meio da seleção natural, sabe-se que as espécies mudam ao longo do tempo geológico.
