This thesis explores preschool class children’s meaning making processes when they encounter evolution. By adopting social semiotic and sociocultural perspectives on meaning making, three group-based tasks were designed. Video data from the activities were analysed using a multimodal approach. The analysis focuses on how the communicated science content affects the science focus of the tasks, how different materials function as semiotic resources and influence meaning making, and interactive aspects of doing science in the meaning-making processes. The findings reveal that, by using the provided materials and their previous experiences, the children argue for different reasons for animal diversity and evolution. Throughout the tasks, a child-centric view of life emerged in a salient manner. This means that, apart from the science focus, the children also emphasise other aspects that they find important. The child-centric perspective is suggested to be a strength that enables children to engage in science activities. The results show that the provided materials had three functions. Children use materials as resources providing meaning. This means that the children draw on the meaning potential of the materials, a process that is influenced by their previous experiences. Moreover, in interaction with peers, the materials also serve as communicative and argumentative tools. Thus, access to materials influences the children’s meaning making and enables them to discuss evolution and “do science”. The findings also reveal an intimate relationship between task context and interaction. More scripted tasks convey more child–adult interaction (scaffolding) while less scripted tasks, during which children build on previous experiences instead of communicated science content, stimulates child–child interaction (mutual collaboration). In scaffolding interactions, a greater emphasis is placed on the science topic of the task due to guidance from the adult. Consequently, meanings made by children in more scripted tasks are more likely to be “scientifically correct”. However, if the teacher or the adult steps back and allows the children to engage in mutual collaboration, they engage in multiple ways of doing science through evaluating, observing, describing and comparing. Overall, the research reported in this thesis suggests that task contexts and materials have a great impact on children’s meaning making and how science is done. Den här avhandlingen utforskar förskolebarns meningsskapandeprocesser kring evolution. Tre gruppbaserade aktiviteter har designats. Videodata har analyserats utifrån ett multimodalt perspektiv på kommunikation. Analysen fokuserar på hur kommunicerade naturvetenskapliga beskrivningar av evolution påverkar aktiviteternas naturvetenskapliga fokus, materials funktion som semiotiska resurser och påverkan på meningsskapande och interaktiva aspekter av att göra naturvetenskap. Avhandlingens resultat visar att barnen, genom att använda material och sina tidigare erfarenheter, för olika resonemang kring varför djur utvecklas och blir olika. Genomgående har barnens syn på världen en betydande roll för meningsskapandeprocessen. Det betyder att barnen, förutom att fokusera på det naturvetenskapliga innehållet i aktiviteterna, också lägger stor vikt vid andra aspekter som är viktiga för dem. Det barncentrerade perspektivet förslås vara en styrka som möjliggör för barn att delta i och engageras av naturvetenskapliga aktiviteter. De material som barnen har tillgång till de i de olika aktiviteterna har tre funktioner. Barnen använder material som meningsgivande resurser, vilket betyder att barnen använder materialens meningspotential. Denna process påverkas av barnens tidigare erfarenheter. Vidare används materialen som kommunikativa- och argumentativa redskap i interaktion med andra. Tillgången till material påverkar således barnens meningsskapande och möjliggör att de kan diskutera evolution påverkar barnens naturvetenskapliga handlande. Avhandlingens resultat visar på en nära relation mellan uppgifters kontext och interaktion. Mer styrda aktiviteter medför mer interaktion mellan barn och vuxna (scaffolding). Mindre styrda aktiviteter, där barnen bygger på sina tidigare erfarenheter, stimulerar istället interaktion mellan barnen (mutual collaboration). Som ett resultat av den vuxnes agerande, läggs det större vikt vid det naturvetenskapliga innehållet (evolution) i scaffolding-interaktioner. Följaktligen är de meningar som skapas i mer styrda aktiviteter mer i linje med naturvetenskapliga förklaringar till evolution. Samtidigt finns det ett samband mellan att den vuxne kliver åt sidan och att barnen kliver fram och gör naturvetenskapliga handlingar som att utvärdera, observera, beskriva och jämföra. Sammanfattningsvis visar den här avhandlingen att uppgifters kontext och material har stor påverkan på barns meningsskapande och hur de gör naturvetenskap.

Evolutionary computation (EC) techniques are e?cient, nature-inspired pl- ning and optimization methods based on the principles of natural evolution and genetics. Due to their e?ciency and simple underlying principles, these me- ods can be used in the context of problem solving, optimization, and machine learning. A large and continuously increasing number of researchers and prof- sionals make use of EC techniques in various application domains. This volume presents a careful selection of relevant EC examples combined with a thorough examination of the techniques used in EC. The papers in the volume illustrate the current state of the art in the application of EC and should help and - spire researchers and professionals to develop e?cient EC methods for design and problem solving. All papers in this book were presented during EvoWorkshops 2008, which consisted of a range of workshops on application-oriented aspects of EC. Since 1998, EvoWorkshops has provided a unique opportunity for EC researchers to meet and discuss applicationaspectsofECandhasservedasanimportantlink between EC research and its application in a variety of domains. During these ten years new workshops have arisen, some have disappeared, while others have matured to become conferences of their own, such as EuroGP in 2000, EvoCOP in 2004, and EvoBIO last year.

This book unifies general concepts of plant and animal virus evolution and covers a broad range of topics related to theoretical and experimental aspects of virus population dynamics and viral fitness. Timely topics such as viral mechanisms to cope with antiviral agents, the adaptability of the virus to new hosts, emergence of new viral phenotypes, and the connections between short- and long-term virus evolution are included. By comparing plant and animal viruses, universal mechanisms responsible for fitness variations, viral emergence and disease mechanisms are explored. Although emphasis is put on specific plant and human viral pathogens, relevant similarities and differences to other viruses are highlighted. Additionally, readers will learn more about the adaptability of coronaviruses, including the recently emerged SARS-CoV-2, the causative agent of the COVID-19 pandemic. The book is aimed at students and scientists interested in basic and applied aspects of plant and animal virus population dynamics and evolution.

Computational models are invaluable in understanding the complex effects of physical processes and environmental factors which interact to influence landform evolution of geologic time scales. This book provides a holistic guide to the construction of numerical models to explain the co-evolution of landforms, soil, vegetation and tectonics, and describes how the geomorphology observable today has been formed. It explains the science of the physical processes and the mechanics of how to solve them, providing a useful resource for graduates studying geomorphology and sedimentary and erosion processes. It also emphasises the methods for assessing the relative importance of different factors at field sites, enabling researchers to select the appropriate processes to model. Integrating a discussion of the fundamental processes with mathematical formulations, it guides the reader in understanding which processes are important and why; and creates a framework through which to study the interaction of soils, vegetation and landforms over time.

Evolution of Nervous Systems, Second Edition, Four Volume Set is a unique, major reference which offers the gold standard for those interested both in evolution and nervous systems. All biology only makes sense when seen in the light of evolution, and this is especially true for the nervous system. All animals have nervous systems that mediate their behaviors, many of them species specific, yet these nervous systems all evolved from the simple nervous system of a common ancestor. To understand these nervous systems, we need to know how they vary and how this variation emerged in evolution. In the first edition of this important reference work, over 100 distinguished neuroscientists assembled the current state-of-the-art knowledge on how nervous systems have evolved throughout the animal kingdom. This second edition remains rich in detail and broad in scope, outlining the changes in brain and nervous system organization that occurred from the first invertebrates and vertebrates, to present day fishes, reptiles, birds, mammals, and especially primates, including humans. The book also includes wholly new content, fully updating the chapters in the previous edition and offering brand new content on current developments in the field. Each of the volumes has been carefully restructured to offer expanded coverage of non-mammalian taxa, mammals, primates, and the human nervous system. The basic principles of brain evolution are discussed, as are mechanisms of change. The reader can select from chapters on highly specific topics or those that provide an overview of current thinking and approaches, making this an indispensable work for students and researchers alike. Presents a broad range of topics, ranging from genetic control of development in invertebrates, to human cognition, offering a one-stop resource for the evolution of nervous systems throughout the animal kingdom Incorporates the expertise of over 100 outstanding investigators who provide their conclusions in the context of the latest experimental results Presents areas of disagreement and consensus views that provide a holistic view of the subjects under discussion
