El maestro de la divulgación y autor de La escritura de los dioses nos traslada a uno de los momentos cumbre de la historia de la ciencia: el descubrimiento de los dinosauriosA comienzos del siglo XIX, el mundo parecia un lugar previsible. La gente creia que la Tierra no tenia mas que seis mil años de antiguedad y que las enormes huellas fosilizadas que aparecian en la naturaleza pertenecian a dragones o a seres mitologicos. Fueron personajes como Mary Anning, una humilde mujer que tenia aficion por recoger fosiles, William Buckland, un excentrico geologo, o Richard Owen, el primero en acuñar la palabra dinosaurio, quienes permitieron que los cientificos de la epoca victoriana pudieran reconstruir la historia de unas criaturas que hoy todos conocemos.Con el rigor historico y el pulso narrativo propios de Edward Dolnick, este libro nos descubre como el hallazgo de los dinosaurios significo el nacimiento de la paleontologia como disciplina, sento las bases de la historia natural moderna y demostro que la edad de nuestro planeta no se media en miles de años, sino en millones, cambiando para siempre nuestra comprension del mundo.Dolnick demuestra un dominio total del tema y construye una historia exhaustiva y muy atractiva.

Hace millones de años, en un paisaje africano sometido a profundas transformaciones climáticas, algunos primates comenzaron a cambiar su relación con el entorno. No solo se adaptaron, empezaron a transformarlo. Desde entonces, la historia de nuestra especie ha sido la de una construccion progresiva en la que genetica, alimentacion, tecnologia, comunicacion y simbolismo se entrelazan para dar forma a lo que somos hoy.Eudald Carbonell e Igor Parra, junto a un equipo de especialistas en genomica, paleoantropologia y arqueologia, proponen en este libro una nueva y ambiciosa interpretacion de la evolucion humana articulada en seis grandes pilares. A traves de ellos reconstruyen el proceso de hominizacion y humanizacion como un fenomeno biologico y, al mismo tiempo, tecnico y social.Desde las primeras herramientas de piedra hasta la revolucion tecnologica contemporanea, este ensayo invita a comprender nuestra trayectoria como especie y a reflexionar sobre el papel que desempeñamos en el futuro del planeta. Una mirada rigurosa y accesible para entender el pasado y asumir, con conciencia, el desafio de lo que esta por venir.

What is a folk tale, but a tangled woodland of words, where anything could happen? Ever since the last ice melted, trees have been our constant companions. Trees have transformed us, protected us, inspired us and created bridges for us. They will continue to shape our lives as we walk into an uncertain future.The islands of Britain and Ireland hold a rich heritage of folk tales, history, knowledge and song about trees. It is a living heritage, changing all the time through the circling year as oak and rowan are joined by spruce and plane, and as old stories are reworked and new ones created.Following the wheel of the year, storyteller and ecologist Lisa Schneidau brings our trees alive through their stories and songs, whether they are rooted in rural magic or modern myth. Take a fresh look at the tree-folk you share your life with, and discover their stories.

Many people as they get older have to face leaving a village or town they have loved, a place redolent with memories and connections, to relocate somewhere more as they say manageable. It is different for everyone, and not always easy, for our ghosts go with us.But everything connects with everything else. There is no such thing as a new beginning. Such a move need not be a matter for repining and regret, but a new adventure.This book records just that journey, of having to learn that new place to which Time is bringing you and populate it with its own stock of private memories.Charles Moseley writes about his move from a fenland village to the nearby historic little city of Ely and breathes life into the history, natural world and people who have made his new home what it is today.

Gods Providential Work in Creation Before Life Began God has been present and active in creation from the moment he created it ex nihilo. Few Christians would question this claim, but its implications for ongoing theology and science dialogues have not been fully explored.In this pathbreaking and field-advancing work, Ross Hastings brings his expertise in both scientific and theological disciplines to bear on the topic of divine providence in chemical evolution. Based on the latest research in the developing field of chemical evolution and the work of theological giants such as Karl Barth, Hastings shows how God may have been providentially and non-competitively at work in the process by which simple prebiotic molecules gave rise to the complex molecules in the first living organisms.In God and Molecules, Hastings provides cutting-edge theological engagement with the developing scientific field of chemical evolution, advances the discussion in theology and science with this new integrative work, and offers a holistic alternative for thinking about chemical evolution that overcomes the binary of theology versus science. God and Molecules pushes toward new frontiers in theology and science and casts a compelling, integrative, and ultimately healing vision for how God has been lovingly involved in the developmental process of the earliest life on earth.
