DOWNLOAD EBOOKThe vertebrate head is the most complex part of the animal body and its diversity in nature reflects a variety of life styles, feeding modes, and ecological adaptations. This book will take you on a journey to discover the origin and diversification of the head, which evolved from a seemingly headless chordate ancestor. Despite their structural diversity, heads develop in a highly conserved fashion in embryos. Major sensory organs like the eyes, ears, nose, and brain develop in close association with surrounding tissues such as bones, cartilages, muscles, nerves, and blood vessels. Ultimately, this integrated unit of tissues gives rise to the complex functionality of the musculoskeletal system as a result of sensory and neural feedback, most notably in the use of the vertebrate jaws, a major vertebrate innovation only lacking in hagfishes and lampreys. The cranium subsequently further diversified during the major transition from fishes living in an aquatic environment to tetrapods living mostly on land. In this book, experts will join forces to integrate, for the first time, state-of-the-art knowledge on the anatomy, development, function, diversity, and evolution of the head and jaws and their muscles within all major groups of extant vertebrates. Considerations about and comparisons with fossil taxa, including emblematic groups such as the dinosaurs, are also provided in this landmark book, which will be a leading reference for many years to come.

DOWNLOAD EBOOKDr. Tilly Edinger's first published paper dealt with a brain cast-in more exact terms an endocast of the cranial cavity-of Noth08auru8, a Triassic relative of the plesiosaurs. With this she embarked on a working lifetime of devotion to paleoneurology, a field of study that she was to transform. A daughter of the famous neurologist Ludwig Edinger, it was appropriate as well as fortunate that her early interest in fossil vertebrates should have become focused upon the recovery of such information concerning the history of the central nervous system as could be obtained from fossil material. Her father evidently had no direct influence upon her choice of· this then obscure and difficult subject, although within the family circle she presumably absorbed from him some appreciation of neoneurology. Indirectly, however, through his accumulation in Frankfurt of an outstanding collection of recent brains, he provided the comparative material essential to her studies during the years she spent there. Early in her career she published Die FOBsilen Gehirne (1929). Here was gathered together for the first time nearly all the widely scattered information on the topic. It had an immediate effect. As one author justly remarked, this "invaluable review . . . serves not only as a basis for continuing and systematizing research on brain casts but also as an indication of the more serious gaps in present knowledge" (Simpson, 1933). The bibliography appended to it listed 250 titles. A bibliography she published in 1937 included 160 additional titles.

DOWNLOAD EBOOKWhat, precisely, is a primitive fish? Most biologists would agree that the living cyclostomes, selachians, crossopterygians, etc. cannot be considered truly primitive. However, they and the fossil record have served to provide the information which forms the basis for speculation concerning the nature of the original vertebrates. This symposium of biologists from a variety of disciplines was called together to create collectively, from the best available current evidence, a picture of the probable line of evolution of the prototype primitive fishes. The symposium was designed to follow one that took place in Stockholm in 1967, convened for a similar purpose, with about the same number of participants. It is a matter of interest that almost the entire 1967 symposium (Nobel Symposium 4) dealt only with the hard tissues, whether fossil or modern. In charting the course of the present symposium it was felt that the intervening years have produced numerous lines of new evidence that could be employed in the same way that a navigator determines his position. Each field, be it adult morphology, geology, ecology, biochemistry, development or physiology, generates evidence that can be extrapolated backward from existing vertebrate forms and forward from invertebrate forms. If the intersect of only two lines of evidence produces a navigational "fix" of rather low reliability, then an intersect, however unfocussed, of multiple guidelines from more numerous disciplines might provide a better position from which to judge early vertebrate history.
