The Martians explores the CIA's top-secret search for the Martians, multiple photos of strange anomalies, and the latest revelations about the environment and water on Mars. And most tantalizing of all: Did an ailing Martian race come to Earth in past eons and were they confused with gods? The questions concerning life on Mars - then and now - are many. The answers are astounding.

El origen de las especies es un libro de Charles Darwin publicado el 24 de noviembre de 1859, considerado uno de los trabajos precursores de la literatura científica y el fundamento de la teoría de la biología evolutiva. Presentó pruebas de que la diversidad de la vida surgió de la descendencia común a través de un patrón ramificado de evolución. Darwin incluyó las pruebas que reunió en su expedición en el viaje del Beagle en la década de 1830 y sus descubrimientos posteriores mediante la investigación, la correspondencia y la experimentación.

Spontaneous generation of living organisms - life arising without progenitor or seed - was a common belief in the time of Aristotle. Over the next 2,000 years, support for spontaneous generation slowly retreated to its final stronghold: spontaneous formation of the first living organism.

The study of human evolution is advancing rapidly. Newly discovered fossil evidence is adding ever more pieces to the puzzle of our past, while revolutionary technological advances in the study of ancient DNA are completely reshaping theories of early human populations and migrations. In this Very Short Introduction, Bernard Wood traces the history of paleoanthropology from its beginnings in the 18th century to the very latest fossil finds.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

In this extraordinary follow-up to the critically acclaimed The Lucifer Principle, Howard Bloom - one of today's preeminent thinkers - offers us a bold rewrite of the evolutionary saga. Global Brain is more than just a brilliantly original contribution to the ongoing debate on the inner workings of evolution; it is a "grand vision," says the eminent evolutionary biologist David Sloan Wilson, a work that transforms our very view of who we are and why.

In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. Lead researcher Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so. Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid.

Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don't see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones and Bird Songs guides the listener through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter.

Cooperation is the means by which life arose in the first place. It’s how we progressed through scale and complexity, from free-floating strands of genetic material, to nation states. But given what we know about the mechanisms of evolution, cooperation is also something of a puzzle. How does cooperation begin, when on a Darwinian level, all that the genes in your body care about is being passed on to the next generation? A biologist by training, Raihani looks at where and how collaborative behavior emerges throughout the animal kingdom, and what problems it solves.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. The human brain, and its evolutionary journey, is unlike anything else in history. In A History of the Human Brain, Bret Stetka takes listeners through that far-reaching journey. He also tackles the question of where the brain will take us next, exploring the burgeoning con­cepts of epigenetics and new technologies like CRISPR.

Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. How can it be possible that the world we see is not objective reality? And how can our senses be useful if they are not communicating the truth? Hoffman grapples with these questions and more over the course of this eye-opening work.

Human life, and how we came to be, is one of the greatest scientific and philosophical questions of our time. This compact and accessible book presents a modern view of human evolution. Written by a leading authority, it lucidly and engagingly explains not only the evolutionary process, but the technologies currently used to unravel the evolutionary past and emergence of Homo sapiens.

In this paradigm-shattering book, biologist Mark W. Moffett draws on findings in psychology, sociology, and anthropology to explain the social adaptations that bind societies. He explores how the tension between identity and anonymity defines how societies develop, function, and fail. Surpassing Guns, Germs, and Steel and Sapiens, The Human Swarm reveals how mankind created sprawling civilizations of unrivaled complexity - and what it will take to sustain them.

V. S. Ramachandran is at the forefront of his field - so much so that Richard Dawkins dubbed him the "Marco Polo of neuroscience". Now, in a major new work, Ramachandran sets his sights on the mystery of human uniqueness. Taking us to the frontiers of neurology, he reveals what baffling and extreme case studies can teach us about normal brain function and how it evolved.

El ingenio de Millás y la sabiduría de Arsuaga unidos para contar la vida como la mejor de las historias.

From the man behind the popular Wired series "Absurd Creature of the Week", a fun, fascinating collection of unique animals and the unbelievable evolutionary traits they use to survive the most extreme scenarios: zombie ants mind-controlled by a fungus; beautiful salamanders that can regenerate any part of their bodies including their brains; and much more.

The compelling story of the effect of Charles Darwin's book On the Origin of Species on a diverse group of American writers, abolitionists, and social reformers, including Henry David Thoreau and Bronson Alcott, in 1860.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.
