Book Description
Stephen Jay Gould borrowed from Winston Churchill when he described the conodont animal as a "riddle wrapped in a mystery inside an enigma." This animal confounded science for more than a century. Some thought it a slug, others a fish, a worm, a plant, even a primitive ancestor of ourselves. The list of possibilities grew and yet an answer to the riddle never seemed any nearer. Would the animal that left behind these miniscule fossils known as conodonts ever be identified? Three times the animal was "found," but each was quite a different animal. Were any of them really the one? Simon J. Knell takes the reader on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy. Today the conodont animal remains perhaps the most disputed creature in the zoological world.

Book Description
A fascinating, comprehensive, accessible account of conodont fossils—one of paleontology’s greatest mysteries: “Deserves to be widely read and enjoyed” (Priscum). Stephen Jay Gould borrowed from Winston Churchill when he described the eel-like conodont animal as a riddle wrapped in a mystery inside an enigma. The search for its identity confounded scientists for more than a century. Some thought it a slug, others a fish, a worm, a plant, even a primitive ancestor of ourselves. As the list of possibilities grew, an answer to the riddle never seemed any nearer. Would the animal that left behind the miniscule fossils known as conodonts ever be identified? Three times the creature was found, but each was quite different from the others. Were any of them really the one? Simon J. Knell takes the reader on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy.

Book Description
This 2-volume set provides a state-of-the-art study of the fossil record and taxonomy of the main vertebrate groups from Greece. Greece stands between 3 continents and its vertebrate fossil record is of great importance for paleontological and evolutionary studies in Europe, Asia and Africa. Fossils from classic, world-famous localities (e.g., Pikermi, Samos) form an essential part of the collections of the most important museums in the world and have been studied by numerous scientists. Recent paleontological research led to the discovery and study of numerous new sites. The volumes contain a taxonomic review of all named and identified taxa, their taxonomic history and current status, as well as historical, phylogenetic and biogeographic information. Volume 1 contains a synopsis of the fossil record and taxonomy of important groups of vertebrates represented in the fossil record of Greece. The volume deals with some of the early splitting clades, including the basal and enigmatic conodonts and basal tetrapods like fishes, amphibians, and reptiles like lizards, snakes, crocodiles, turtles and tortoises. The second part of the volume deals with basal mammalian clades, some of which are quite characteristic for the fossil record of the country: aardwarks, hyraxes, proboscideans, elephants and mammoths, sea cows, rodents, and lagomorphs. The volume ends with special chapters on the primate fossil record of the country, including some of our most recent and distant relatives.

Book Description
Evolutionists have long known that Charles Darwin's original argument against his own theory - that a lack of fossil evidence of transitional forms would reduce him to an embarrassing footnote in history - was screamingly true. No legitimate fossil evidence exists that shows one species changing into another. This startling realization led Luther Sunderland to an exhaustive search of the subject, and his findings show clearly that evolution is a theory in disarray. From his own interviews with leading evolutionists, and an examination of the fossil evidence, Sunderland shows that the Enigma of Darwin's anti-God philosophy is that the facts show it is anything but rock-solid. Before is death in 1987, Luther Sunderland had garnered the respect of creationists worldwide for his investigative writing of the evolution controversy. After obtaining an engineering degree from Penn State University, Sunderland spent 30 years developing automatic flight control systems for the General Electric Company. DARWIN'S ENIGMA remains on intensely popular work on the theory of origins.

Book Description
The Museum’s Borders demonstrates that museum practices are deeply entangled in border making, patrol, mitigation and erasure, and that the border lens offers a new tool for deconstructing and reconfiguring such practices. Arguing that the museum is a critical institution for the operation of knowledge-based democracies, Knell investigates how they have been used by scientists, art historians and historians to construct our bordered world. Examining the role of museums in the Windrush scandal in Britain, the exclusion of Black artists in America, ideological and propaganda discourses in Europe and China, and the remembering of contested pasts in the Balkans, Knell argues for the importance of museums in countering unethical, nationalistic, post-fact political discourse. Using the principles of Knell’s ‘Contemporary Museology’, The Museum’s Borders considers the significance of the museum for societies that wish to know and remember in ways that empower citizens and build cohesive societies. The book will be of great interest to students and academics engaged in the study of museums and heritage, art history, science studies, cultural studies, anthropology, memory studies and history. It is required reading for museum professionals seeking to adopt non-discriminatory practices.

Book Description
"Fossils are the fragments from which, piece by laborious piece, the great mosaic of the history of life has been constructed. Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this—the greatest biography of all—is one in whose closing pages we find ourselves."—from Origins In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life’s past, its long and slow development, and its intricate interdependencies. Rhodes’s accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

Book Description
It 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. Capacities 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.
