The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

A multi-author volume Major Events in Early Vertebrate Evolution examines the origin and early evolution of the backboned animals (vertebrates)-the group which comprises all fishes, amphibians, reptiles, birds and mammals, including ourselves. This volume draws together evidence from fossils, genes, and developmental biology (the study of how embry

The field of cognitive psychology has expanded rapidly in recent years, with experts in affective and cognitive neuroscience revealing more about mammalian brain function than ever before. In contrast, psychological problems such as ADHD, autism, anxiety, and depression are on the rise, as are medical conditions such as diabetes, obesity, and autoimmune disorders. Why, in this era of unprecedented scientific self-knowledge, does there seem to be so much uncertainty about what human beings need for optimal development? Evolution, Early Experience and Human Development asserts that human development is being misshaped by government policies, social practices, and public beliefs that fail to consider basic human needs. In this pioneering volume, scientists from a range of disciplines theorize that the increase in conditions such as depression and obesity can be partially attributed to a disparity between the environments and conditions under which our mammalian brains currently develop and our evolutionary heritage. For example, healthy brain and emotional development depends to a significant extent upon caregiver availability and quality of care. These include practices such as breastfeeding, co-sleeping, and parental social support, which have waned in modern society, but nevertheless may be integral to healthy development. As the authors argue, without a more informed appreciation of the ideal conditions under which human brains/minds develop and function, human beings will continue to struggle with suboptimal mental and physical health, and as problems emerge psychological treatments alone will not be effective. The best approach is to recognize these needs at the outset so as to optimize child development. Evolution, Early Experience and Human Development puts forth a logical, empirically based argument regarding human mammalian needs for optimal development, based on research from anthropology, neurobiology, animal science, and human development. The result is a unique exploration of evolutionary approaches to human behavior that will support the advancement of new policies, new attitudes towards health, and alterations in childcare practices that will better promote healthy human development.

Origin and Early Evolution of Life draws on evidence from molecular genetics, the structure and function of extant organisms, and geology. It covers the period from about 4 billion years ago, when life is thought to have originated, to about 600 million years ago when multicellular organisms first arose. There are significant gaps in our understanding of the earliest evolution of life forms, but an insight into the topic leads to a more profound understanding of life itself. Particular emphasis is placed on the fact that although life arose very soon after the origin of the Earth, it was represented only by simple microbial life forms for approximately 85% of this time. Increase in complexity beyond the microbial level took place only very late in the history of life.

It is now accepted that the first cells derived from simpler "objects", and that their descendants became more and more complicated and ordered until their evolutionary transformation into modern cells, namely, cells endowed with the same basic structures and mechanisms as those existing today. Although the appearance of the first modern cells goes back at least two billion years, many scholars believe that it occurred almost four billion years ago. In that case, the Earth's formation, which took place quite quickly about 4. 6 billion years ago, is in close proximity to the originoflife. There is disagreement not only about the moment ofappearance ofmodern cells, but also as to their early evolution. Ideas on the first steps in cellular evolution vary considerably, and our present knowledge is so limited as to be little more than vacuous. Why discuss it then? Precisely because it is an empty space that needs to be filled! Does it make sense only to discuss things which are well-known and well documented? Is this the best way to interpret that spirit of exploration of the unknown which is at the very heartofscientific endeavor? The idea that it is idle to venture into fields which are poorly documented has been long supported, even in cases similar to those dealt with here, for example, the evolutionary phases which took place before the first cell.
