La era de la genómica ha abierto un nuevo frente para estudiar la evolución humana, que hasta ahora se basaba únicamente en la interpretación de restos arqueológicos y paleontológicos. Nuevas técnicas de secuenciación masiva en paralelo desarrolladas en los últimos años han permitido recuperar el genoma de los neandertales y el de los denisovanos, en lo que sin duda ha sido uno de los mayores logros científicos del siglo XXI. Los neandertales fueron una especie humana con rasgos físicos muy característicos que habitó Europa y el oeste de Asia hace entre unos 400.000 y unos 30.000 años. Paralelamente, otros humanos, conocidos como denisovanos y de los cuales se desconoce prácticamente todo, habrían evolucionado en Asia. La expansión por Eurasia de los humanos modernos procedentes de África, conllevó su proceso de extinción. Pero la naturaleza exacta de las interacciones entre estos tres tipos de humanos, el significado adaptativo de su morfología peculiar y el alcance real de sus capacidades cognitivas, son todavía motivos de controversia entre los investigadores. Los paleogenomas descifrados han dado a conocer un listado de genes que difieren entre nosotros y estos otros linajes humanos, lo que ayudará a generar una definición objetiva de nuestra especie. Asimismo, han proporcionado evidencias genómicas de cruzamientos con nuestros antepasados, hace menos de 100.000 años. Este descubrimiento ha transformado el paradigma vigente de la evolución humana y generado un modelo mucho más complejo sobre el origen de nuestra especie.
El espejo humeante
Author: Greco Hernández Ramírez
Publisher: Siglo XXI
Una revolución tecnológica y conceptual sin precedentes está acaeciendo en la biología contemporánea. Esta revolución nos está transportando a “escenarios inéditos, estrafalarios e inimaginables” hasta hace apenas unos años, en los que, por ejemplo, dejaremos de envejecer, generaremos una nueva humanidad clónica, o un nuevo tipo de medicina genómica y personalizada. Con un estilo erudito, riguroso y claro, en este texto de divulgación científica Greco Hernández nos muestra las profundas consecuencias que esta revolución tendrá para la humanidad. Entre ellas, provocará que muchas de las certezas más firmes que el ser humano tiene de sí mismo, como el significado de “vida” y “muerte”, o de “ser” humano, tengan que cambiar pronto y para siempre.
This invaluable book provides a quick introduction to the rudiments of perturbative string theory and a detailed introduction to the more current topic of D-brane dynamics. The presentation is very pedagogical, with much of the technical detail streamlined. The rapid but highly coherent introduction to the subject is perhaps what distinguishes this book from other string theory or D-brane books. This second edition includes an additional appendix with solutions to the exercises, thus expanding on some of the technical material and making the book more appealing for use in lecture courses. The material is based on mini-courses in theoretical high energy physics delivered by the author at various summer schools, so its actual level has been appropriately tested.
Examines fundamental problems often overlooked or neglected in education. These problems are presented as "seven complex lessons" that should be covered in an education of the future in all societies in every culture, according to means and rules appropriate to those societies and cultures.
My European Family
Author: Karin Bojs
Publisher: Bloomsbury Publishing
Karin Bojs grew up in a small, broken family. At her mother's funeral she felt this more keenly than ever. As a science journalist she was eager to learn more about herself, her family and the interconnectedness of society. After all, we're all related. And in a sense, we are all family. My European Family tells the story of Europe and its people through its genetic legacy, from the first wave of immigration to the present day, weaving in the latest archaeological findings. Karin goes deep in search of her genealogy; by having her DNA sequenced she was able to trace the path of her ancestors back through the Viking and Bronze ages to the Neolithic and beyond into prehistory, even back to a time when Neanderthals ran the European show. Travelling to dozens of countries to follow the story, she learns about early farmers in the Middle East and flute-playing cavemen in Germany and France, and a whole host of other fascinating characters. This book looks at genetics from a uniquely pan-European perspective, with the author meeting dozens of geneticists, historians and archaeologists in the course of her research. The genes of this seemingly ordinary modern European woman have a truly fascinating story to tell, and in many ways it is the true story of Europe. At a time when politics is pushing nations apart, this book shows that, ultimately, our genes will always bind us together.
A study of the Burgess Shale, a sea bed 530 million years old, and attempts to tackle what the findings are and what it means
Author: Pat Shipman
Publisher: Harvard University Press
Humans domesticated dogs soon after Neanderthals began to disappear. This alliance between two predator species, Pat Shipman hypothesizes, made possible unprecedented success in hunting large Ice Age mammals—a distinct and ultimately decisive advantage for human invaders at a time when climate change made both humans and Neanderthals vulnerable.
Author: Matt Ridley
Publisher: Harper Collins
The genome's been mapped. But what does it mean? Arguably the most significant scientific discovery of the new century, the mapping of the twenty-three pairs of chromosomes that make up the human genome raises almost as many questions as it answers. Questions that will profoundly impact the way we think about disease, about longevity, and about free will. Questions that will affect the rest of your life. Genome offers extraordinary insight into the ramifications of this incredible breakthrough. By picking one newly discovered gene from each pair of chromosomes and telling its story, Matt Ridley recounts the history of our species and its ancestors from the dawn of life to the brink of future medicine. From Huntington's disease to cancer, from the applications of gene therapy to the horrors of eugenics, Matt Ridley probes the scientific, philosophical, and moral issues arising as a result of the mapping of the genome. It will help you understand what this scientific milestone means for you, for your children, and for humankind.
After being widely rejected in the late 20th century the work of Karl Marx is now being reassessed by many theorists and activists. Karl Marx, Anthropologist explores how this most influential of modern thinkers is still highly relevant for Anthropology today. Marx was profoundly influenced by critical Enlightenment thought. He believed that humans were social individuals that simultaneously satisfied and forged their needs in the contexts of historically particular social relations and created cultures. Marx continually refined the empirical, philosophical, and practical dimensions of his anthropology throughout his lifetime. Assessing key concepts, from the differences between class-based and classless societies to the roles of exploitation, alienation and domination in the making of social individuals, Karl Marx, Anthropologist is an essential guide to Marx's anthropological thought for the 21st century.
Why Evolution is True
Author: Jerry A. Coyne
Publisher: OUP Oxford
For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.

The book presents an integrative review of paleoneurology, the study of endocranial morphology in fossil species. The main focus is on showing how computed methods can be used to support advances in evolutionary neuroanatomy, paleoanthropology and archaeology and how they have contributed to creating a completely new perspective in cognitive neuroscience. Moreover, thanks to its multidisciplinary approach, the book addresses students and researchers approaching human paleoneurology from different angles and for different purposes, such as biologists, physicians, anthropologists, archaeologists and computer scientists. The individual chapters, written by international experts, represent authoritative reviews of the most important topics in the field. All the concepts are presented in an easy-to-understand style, making them accessible to university students, newcomers and also to anyone interested in understanding how methods like biomedical imaging, digital anatomy and computed and multivariate morphometrics can be used for analyzing ontogenetic and phylogenetic changes according to the principles of functional morphology, morphological integration and modularity.

The Beautiful Brain
Author: Larry W. Swanson, Eric Newman, Alfonso Araque, Janet M. Dubinsky
At the crossroads of art and science, Beautiful Brain presents Nobel Laureate Santiago Ramón y Cajal’s contributions to neuroscience through his groundbreaking artistic brain imagery. Santiago Ramón y Cajal (1852–1934) was the father of modern neuroscience and an exceptional artist. He devoted his life to the anatomy of the brain, the body’s most complex and mysterious organ. His superhuman feats of visualization, based on fanatically precise techniques and countless hours at the microscope, resulted in some of the most remarkable illustrations in the history of science. Beautiful Brain presents a selection of his exquisite drawings of brain cells, brain regions, and neural circuits with accessible descriptive commentary. These drawings are explored from multiple perspectives: Larry W. Swanson describes Cajal’s contributions to neuroscience; Lyndel King and Eric Himmel explore his artistic roots and achievement; Eric A. Newman provides commentary on the drawings; and Janet M. Dubinsky describes contemporary neuroscience imaging techniques. This book is the companion to a traveling exhibition opening at the Weisman Art Museum in Minneapolis in February 2017, marking the first time that many of these works, which are housed at the Instituto Cajal in Madrid, have been seen outside of Spain. Beautiful Brain showcases Cajal’s contributions to neuroscience, explores his artistic roots and achievement, and looks at his work in relation to contemporary neuroscience imaging, appealing to general readers and professionals alike.
