In our unique genomes, every one of us carries the story of our species—births, deaths, disease, war, famine, migration, and a lot of sex.
But those stories have always been locked away—until now.
Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has blown the lid off what we thought we knew. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story—from 100,000 years ago to the present.
A Brief History of Everyone Who Ever Lived will upend your thinking on Neanderthals, evolution, royalty, race, and even redheads. (For example, we now know that at least four human species once roamed the earth.) Plus, here is the remarkable, controversial story of how our genes made their way to the Americas—one that’s still being written, as ever more of us have our DNA sequenced.
Rutherford closes with “A Short Introduction to the Future of Humankind,” filled with provocative questions that we’re on the cusp of answering: Are we still in the grasp of natural selection? Are we evolving for better or worse? And . . . where do we go from here?

What teeth can teach us about the evolution of the human species
Whether we realize it or not, we carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution's Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution and climate change with new approaches to uncovering dietary clues from fossil teeth to present a remarkable investigation into the ways that teeth―their shape, chemistry, and wear―reveal how we came to be.
Ungar describes how a tooth's "foodprints"―distinctive patterns of microscopic wear and tear―provide telltale details about what an animal actually ate in the past. These clues, combined with groundbreaking research in paleoclimatology, demonstrate how a changing climate altered the food options available to our ancestors, what Ungar calls the biospheric buffet. When diets change, species change, and Ungar traces how diet and an unpredictable climate determined who among our ancestors was winnowed out and who survived, as well as why we transitioned from the role of forager to farmer. By sifting through the evidence―and the scars on our teeth―Ungar makes the important case for what might or might not be the most natural diet for humans.
Traveling the four corners of the globe and combining scientific breakthroughs with vivid narrative, Evolution's Bite presents a unique dental perspective on our astonishing human development.
Consciousness and the Brain: Deciphering How the Brain Codes Our Thoughts [EPUB]

A breathtaking look at the new science that can track consciousness deep in the brain
How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before.
In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries.
A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.
