Africa remains in continuous transition. Many of its communities are based around ancient or feudal structures, while others have modernized but experienced turbulent times. Modernity in Africa has la
The rapid evolution of radio and radar systems for military use during World War II, and devices to counter them, led to a technological battle that neither the Axis nor the Allied powers could afford
The book interprets the Cuban revolutionary movement from 1868 to 1959 as a continuous process that sought political independence and social and economic transformation of colonial and neocolonial str
Biospeleology, the study of organisms that live in caves, has a tremendous potential to inform many aspects of modern biology; yet this area of knowledge remains largely anchored in neo-Lamarckian views of the natural world in both its approaches and jargon. Written for graduate students and academic researchers, this book provides a critical examination of current knowledge and ideas on cave biology, with emphasis on evolution, ecology, and conservation. Aldemaro Romero provides a historical analysis of ideas that have influenced biospeleology, discusses evolutionary phenomena in caves, from cave colonization to phenotypic and genotypic changes, and integrates concepts and knowledge from diverse biological viewpoints. He challenges the conventional wisdom regarding the biology of caves, and highlights urgent questions that should be addressed in order to get a better and more complete understanding of caves as ecosystems.
“The facts of variability, of the struggle for existence, of adaptation to conditions, were notorious enough; but none of us had suspected that the road to the heart of the species problem lay through

Spectacular observational breakthroughs, particularly by the WMAP satellite, have led to a new epoch of CMB science long after its original discovery. Taking a physical approach, the authors of this volume probe the problem of the 'darkness' of the Universe: the origin and evolution of dark energy and matter in the cosmos. Starting with the observational background of modern cosmology, they provide an accessible review of this fascinating yet complex subject. Topics discussed include the kinetics of the electromagnetic radiation in the Universe, the ionization history of cosmic plamas, the origin of primordial perturbations in light of the inflation paradigm, and the formation of anisotropy and polarization of the CMB. This fascinating review will be valuable to advanced students and researchers in cosmology.

Cave organisms are the ‘monsters’ of the underground world and studying them invariably raises interesting questions about the ways evolution has equipped them to survive in permanent darkness and low
In praise of imperfection: how life on our planet is a catalog of imperfections, errors, alternatives, and anomalies.In the beginning, there was imperfection, which became the source of all things. Anomalies and asymmetries caused planets to take shape from the bubbling void and sent light into darkness. Life on earth is a catalog of accidents, alternatives, and errors that turned out to work quite well. In this book, Telmo Pievani shows that life on our planet has flourished and survived not because of its perfection but despite (and perhaps because of) its imperfection. He begins his story with the disruption-filled birth of the universe and proceeds through the random DNA copying errors that fuel evolution, the transformations of advantages into handicaps by natural selection, the anatomical and functional jumble that is the human brain, and our many bodily mismatches. Along the way, Pievani tells readers about the Irish elk (incidentally, neither Irish nor elk), whose enormous antl
