In the golden age of dinosaur discoveries, paleontologists are frequently learning about new dinosaurs and new facts about already-known species. At least 14 dinosaurs made the headlines in 2014 alone. Blending fiction with fact, Top 10 Dinosaurs of 2014 reimagines the way 10 of the newly described Jurassic and Cretaceous dinosaurs lived in their natural habitats.

Ian Tattersall, a highly esteemed figure in the fields of anthropology, archaeology, and paleontology, leads a fascinating tour of the history of life and the evolution of human beings. Starting at the very beginning, Tattersall examines patterns of change in the biosphere over time, and the correlations of biological events with physical changes in the Earth's environment.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

La aparición de los primeros restos de Neandertales supuso una revolución científica y un golpe a los mismos cimientos de los sectores religiosos más dogmáticos. La aparición de los primeros fósiles humanos en el valle de Neander, en 1856, supuso una auténtica revolución, tanto científica como en el resto de disciplinas.

Although we usually think of technology as something unique to modern times, our ancestors began to create the first technologies millions of years ago in the form of prehistoric tools and weapons. Over time, eight key technologies gradually freed us from the limitations of our animal origins.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

Thirty thousand years ago our prehistoric ancestors painted perfect images of animals on walls of tortuous caves, most often without any light. How was this possible? Scholars and archaeologists have for centuries pored over these works of art, speculating and hoping to come away with the key to the mystery. David and Lefrre give us a new understanding of an art lost in time, revealing what had until recently remained unexplainable - the oldest enigma in humanity has been solved.

How is it that we came to be here? The search for answers to that question has preoccupied humans for millennia. Scientists have sought clues in the genes of living things; in the physical environments of Earth, from mountaintops to the depths of the ocean; in the chemistry of this world and those nearby; in the tiniest particles of matter; and in the deepest reaches of space. In Islands of the Cosmos, Dale A. Russell traces a path from the dawn of the universe to speculation about our future on this planet.

A fresh look at the Genesis account of creation - identifying the key errors of evolution and young-earth creationism, then combining their truths to formulate a simple but scripturally and scientifically accurate new synthesis - the literal truth of Genesis.

Big Bone Lick: The Cradle of American Paleontology recounts the rich history of the fossil site that gave the world the first evidence of the extinction of several mammalian species, including the American mastodon. Big Bone Lick has played many roles: nutrient source, hallowed ground, salt mine, health spa, and a rich trove of wonders. Stanley Hedeen presents a comprehensive narrative of Big Bone Lick from its geological formation forward, explaining why the site attracted animals, regional tribespeople, European explorers and scientists, and eventually American pioneers.

Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

Adored by children and adults alike, tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, triceratops, or velociraptors in Jurassic Park. But despite the hype, tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right and are among the best-studied of all dinosaurs.

In 1990, Peter Larson, with his team of commercial fossil hunters from the Black Hills Institute, discovered the most complete Tyrannosaurus Rex specimen in history. He dubbed it "Sue" after the field paleontologist who first saw it sticking out of a sandstone cliff on the ranch of Maurice Williams, a Cheyenne River Sioux Tribe member in South Dakota's badlands. Because the skelton was 90% complete, its study promised to yield up priceless information on the life and habits of the T Rex.

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.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to enter our awareness only when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, doglike creatures into animals that move like fish and breathe like us and can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past.

The idea of a missing link between humanity and our animal ancestors predates evolution and popular science and actually has religious roots in the deist concept of the Great Chain of Being. Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being "animal" and started being "human". In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion.

Why did the line of ancient humans who eventually evolved into us survive when the others were shown the evolutionary door? Chip Walter draws on new scientific discoveries to tell the fascinating tale of how our survival was linked to our ancestors being born more prematurely than others, having uniquely long and rich childhoods, evolving a new kind of mind that made us resourceful and emotionally complex; how our highly social nature increased our odds of survival; and why we became self aware in ways that no other animal seems to be.

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.
