A través de preciosas imágenes, este libro revela el sentido del color en la naturaleza, muestra cómo lo perciben los distintos seres vivos y aclara hasta qué punto el color contribuye en el comportamiento animal, ya sea en la reproduccion y comunicacion e incluso en el ataque y la defensa. Asimismo, contextualiza la percepcion del color, junto con los usos que le damos a aquellos que nos rodean, tanto en la naturaleza como los que creamos para nuestro uso y disfrute. Presenta un analisis extenso sobre un tema fascinante y cautivador, que le hara descubrir nuevas formas de percibir el mundo que le rodea. Durante los ultimos años, se han producido avances extraordinarios en el estudio de la vision, la ecologia visual y nuestra percepcion multidimensional y compleja del color en la vida y el planeta. Estos avances han sido posibles gracias a hallazgos insolitos en neurociencia y biologia evolutiva, asi como en psicologia y diseño.Incluye un gran numero de asombrosas ilustraciones en color; explica que es el color y como se origina; aborda la fisica, genetica, quimica, fisiologia y psicologia de la percepcion animal del color; analiza los colores que los humanos no ven o apenas utilizan, como los ultravioleta, los infrarrojos y los bioluminiscentes; revela la evolucion de los colores en el apareamiento, la caza, la supervivencia, las artimañas y el camuflaje, y proporciona informacion sobre el daltonismo, los colores bioinspirados y nuestra apreciacion del color en el arte y el diseño.

Una obra puede leerse tanto como introducción a la astronomía extragaláctica como una meditación sobre la ciencia como empresa humana.Islas del universo no es un libro de astronomía convencional. Es, mas bien, el relato apasionado y lucido de una aventura cientifica: la que nos ha permitido descubrir que habitamos un rincon minusculo de un cosmos colmado de galaxias, estrellas y misterios aun sin resolver. Gaspar Galaz, astronomo y divulgador, recorre en estas paginas la historia de como fuimos comprendiendo el universo extragalactico, desde los rudimentarios telescopios de Galileo hasta los colosos opticos del siglo XXI, instalados bajo los cielos privilegiados de Chile.Al mismo tiempo, este libro es tambien una meditacion sobre el conocimiento, el asombro y la humanidad detras de la ciencia. A traves de un lenguaje claro y narrativo, Galaz no solo explica conceptos complejos con sencillez y rigor, sino que rescata los errores, intuiciones y pasiones de quienes, como el, han dedicado su vida a observar lo inmenso. Un homenaje a las galaxias -verdaderas islas en el universo- y tambien a los hombres y mujeres que, desde sus propias islas interiores, se han atrevido a explorar los confines del espacio.

First published in 1876, this two-volume treatise codifies the worlds fauna into six zoogeographic realms: Palearctic, Nearctic, Neotropical, Ethiopian, Oriental, and Australasian, and explains their boundaries through geology, climate, and barriers to dispersal. Wallace integrates exhaustive catalogues with interpretive chapters, using maps, synoptic tables, and bathymetric clues such as shallow seas to infer past connections. Extending P. L. Sclaters avian scheme to vertebrates, his methodical prose offers a Darwinian, historical account that makes biogeography a synthetic science. Wallaces argument grows from lived experience. Years in the Amazon and the Malay Archipelago, where he traced the Wallace Line between Bali and Lombok, gave him intimate knowledge of island faunas, endemism, and migration barriers. As co-formulator of natural selection and an indefatigable collector for museums, he turned field notes, specimen lists, and correspondence with Darwin, Huxley, and Sclater into a principled framework for why species occur where they do. Scholars of evolution, macroecology, and the history of science will find this foundational synthesis indispensable; conservationists and systematists will value its durable logic and global scope. Read it for empirical rigor and conceptual clarity: a master class in converting natural history into theory, and in learning to read the map of life.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

On the Origin of Species is one of the most influential scientific books ever written. In this groundbreaking work, Charles Darwin presents the theory of evolution by natural selection, reshaping biology and humanitys understanding of life on Earth. The 6th edition reflects Darwins refined arguments and responses to critics. Clear, methodical, and revolutionary, this book remains essential reading for students of science, philosophy, and intellectual history.

"There is grandeur in this view of life."In 1859, Charles Darwin published a book that would forever alter the course of human thought. On the Origin of Species introduced the world to the concept of Natural Selectionthe process by which populations of living organisms adapt and change. Moving away from the static view of nature, Darwin presented a world of constant, slow, and magnificent transformation.The Mechanism of Life: Through decades of meticulous observationfrom the beak shapes of Galapagos finches to the breeding of domestic pigeonsDarwin laid out a compelling case for how biological diversity arises. He explains how favorable traits are preserved over generations, allowing species to fill specific niches in their environment.A Masterpiece of Scientific Logic: Despite the controversy it initially sparked, On the Origin of Species is written with remarkable clarity and humility. Darwin anticipates and addresses the potential objections of his contemporaries, grounding his revolutionary ideas in overwhelming evidence from geology, embryology, and paleontology. It remains not just a textbook of biology, but a beautifully written tribute to the interconnectedness of all living things.Explore the foundation of your own history.

The modern world views the forest merely as a backdrop for recreation, forgetting that for most of human history, it was our primary grocery store. As food prices rise and the quality of mass-produced produce declines, the ancient skill of foraging is experiencing a necessary renaissance. Natures Hidden Grocery Aisle bridges the gap between urban life and the wild bounty waiting just outside your door, offering a comprehensive roadmap for those who yearn to eat fresh, organic, and free food but are held back by valid concerns about safety.This guide dismantles the intimidation factor surrounding wild edibles by prioritizing safety above all else. Instead of overwhelming you with thousands of species, it focuses intensely on the "Foolproof 15," a curated selection of delicious plants and mushrooms that have no poisonous look-alikes, ensuring your first foray into the woods is a confident one. You will learn to distinguish a delectable treat from a dangerous toxin through high-definition identification guides and the rigorous application of the Universal Edibility Test.Beyond simple identification, the book dives deep into the ethics of sustainable harvesting to ensure the landscape remains fruitful for generations to come. It explores the surprisingly lush world of urban foraging, teaching you how to spot nutritious greens in city environments while navigating potential pollution zones. From spotting spring shoots to harvesting winter roots, this narrative guide transforms your nature walks into a treasure hunt, empowering you to reclaim your food independence and turn the outdoors into your personal pantry without fear.

Human beings have always wanted to become more just and more altruistic, and hoped that future generations would be morally better than the last. In the past, education, teaching, self-discipline, reading, knowledge, and moral exemplars were the main ways to achieve this. But these methods are sometimes ineffective and take a long time to work, especially in the global context where the survival of the human species is threatened by environmental disasters, pandemics, and terrorism. Some writers claim that to deal with these tremendous challenges, we need to find better ways to make people more moral. Genetics, neuroscience, and pharmacology might allow us to alter human biology to make people more generous, compassionate, and empathic. But the moral bio-enhancement project raises many questions: which human traits or dispositions should we change? Should we change emotions or reason? Does moral bio-enhancement allow for freedom? What kind of freedom does it threaten? Are we already practicing forms of moral bio-enhancement without realizing it? This book tries to answer these questions, providing a map of the debate about moral enhancement.
