The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that Earth is around 4.6 billion years old, but despite all of the scientific advances made in the past few centuries, including an enhanced understanding of Earth’s geological past, relatively little is known about the planet’s early history.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. What humans commonly refer to as the “Ice Age” is actually a series of fluctuating climate events that have occurred throughout the planet’s history. These ongoing historical phenomena are difficult to conceptualize because of both the time frame involved and the natural process by which they cyclically unfold.

The early history of our planet covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that planet Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

Who are we? How do scientists define Homo sapiens, and how does our species differ from the extinct hominins that came before us? In this accessible account palaeoarchaeologist Paul Pettitt shows how the latest scientific advances, especially in genetics, are revolutionizing our understanding of human evolution. Pettitt reveals the extraordinary story of how our ancestors adapted to unforgiving and relentlessly changing climates, leading to remarkable innovations in art, technology, and society that we are only now beginning to comprehend.

A fascinating investigation of the origin of humans based on incredible new discoveries and advanced scientific technology.

In this stunning narrative spanning more than 200 million years, Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field - discovering 10 new species and leading groundbreaking scientific studies and fieldwork - masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy.

Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing 21st-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.

Tracing the migrations of the Denisovans and their interbreeding with Neanderthals and early human populations in Asia, Europe, Australia, and the Americas, Andrew Collins and Greg Little explore how the new mental capabilities of the Denisovan-Neanderthal and Denisovan-human hybrids greatly accelerated the flowering of human civilization over 40,000 years ago. They show how the Denisovans displayed sophisticated advances, including precision-machined stone tools and jewelry, tailored clothing, celestially-aligned architecture, and horse domestication.

In Indigenous Continent, acclaimed historian Pekka Hämäläinen presents a sweeping counternarrative that shatters the most basic assumptions about American history. Shifting our perspective away from Jamestown, Plymouth Rock, the Revolution, and other well-trodden episodes on the conventional timeline, he depicts a sovereign world of Native nations whose members, far from helpless victims of colonial violence, dominated the continent for centuries after the first European arrivals.

Dr. Carl Sagan takes us on a great adventure, offering his vivid and startling insight into the brain of man and beast, the origin of human intelligence, the function of our most haunting legends - and their amazing links to recent discoveries.

In Kindred, Neanderthal expert Becky Wragg Sykes shoves aside the cliché of the shivering ragged figure in an icy wasteland and reveals the Neanderthal you don’t know, who lived across vast and diverse tracts of Eurasia and survived through hundreds of thousands of years of massive climate change. Using a thematic rather than chronological approach, this book will shed new light on where they lived, what they ate and the increasingly complex Neanderthal culture that is being discovered.

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.
