A history of humanity on the brink of decline.

We are living through a period that is unique in human history. For the first time in more than ten thousand years, the rate of human population growth is slowing down. In the middle of this century population growth will stop, and the number of people on Earth will start to decline - fast.

In this provocative book, award-winning science writer Henry Gee offers a concise, brilliantly-told history of our species--and argues that we are on a rapid, one-way trip to extinction. The Decline and Fall of the Human Empire narrates the dramatic rise of humanity, how a scattered range of small groups across several continents eventually inbred, interacted, fought, established stable communities and food supplies, and began the process of dominating the planet. The human story is relatively brief―the oldest fossils of H. Sapiens date to approximately 300,000 years ago―yet the spread of our species has been unstoppable…until recently.

As Gee demonstrates, our population has peaked, and is declining; our environment is becoming inimical to human life in many locations; our core resources of water, arable land, and air are diminishing; and new diseases, simmering conflicts, and ambiguous technologies threaten our collective health. Can we still change our course? Or is our own extinction inevitable?

There could be a way out, but the launch window is narrow.

Unless Homo sapiens establishes successful colonies in space within the next two centuries, our species is likely to stay earthbound and will have vanished entirely within another ten thousand years, bringing the seven-million-year story of the human lineage to an end.

With assured narration, dramatic stories, and his signature sprightly humor, Henry Gee envisions new opportunities for the future of humanity―a future that will reward facing challenges with ingenuity, foresight, and cooperation.

From the winner of the 2022 Royal Society Science Book Prize, a thrilling and thought-provoking account of the rise and fall of humankind.

For the first time in over ten millennia, the rate of human population growth is slowing down. The global population is forecast to begin declining in the second half of this century, and in 10,000 years’ time, our species will likely be extinct.

In The Decline and Fall of the Human Empire, Henry Gee shows how we arrived at this crucial moment in our history, beginning his story deep in the palaeolithic past and charting our dramatic rise from one species of human among many – teetering on the edge of extinction for more than a hundred millennia – to the most dominant animal to ever live on Earth.

But rapid climate change, a stagnating global economy, falling birth rates and an unexplainable decline in average human sperm count are combining to make our chances for longevity increasingly slim. There could be a way forward, but the launch window is narrow.

Gee argues that unless Homo sapiens establishes successful colonies in space within the next two centuries, our species is likely to stay earthbound and will have vanished entirely within another 10,000 years, bringing the seven-million-year story of the human lineage to an end.

Drawing on a dazzling array of the latest scientific research, Gee tells the extraordinary story of humanity with characteristic warmth and wit, and suggests how our exceptional species might avoid its tragic fate.

"Nature" has published news about the history of life ever since its first issue in 1869, in which T. H. Huxley ("Darwin's bulldog") wrote about Triassic dinosaurs. In recent years, the field has enjoyed a tremendous flowering due to new investigative techniques drawn from cladistics (a revolutionary method for charting evolutionary relationships) and molecular biology.
"Shaking the Tree" brings together nineteen review articles written for "Nature" over the past decade by many of the major figures in paleontology and evolution, from Stephen Jay Gould to Simon Conway Morris. Each article is brief, accessible, and opinionated, providing "shoot from the hip" accounts of the latest news and debates. Topics covered include major extinction events, homeotic genes and body plans, the origin and evolution of the primates, and reconstructions of phylogenetic trees for a wide variety of groups. The editor, Henry Gee, gives new commentary and updated references.
"Shaking the Tree" is a one-stop resource for engaging overviews of the latest research in the history of life on Earth.

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, arguing that it reflects a profound misunderstanding of how evolution works and, when applied to the evolution of our own species, supports mistaken ideas about our own place in the universe. Gee presents a robust and stark challenge to our tendency to see ourselves as the acme of creation. Far from being a quirk of religious fundamentalism, human exceptionalism, Gee argues, is an error that also infects scientific thought. Touring the many features of human beings that have recurrently been used to distinguish us from the rest of the animal world, Gee shows that our evolutionary outcome is one possibility among many, one that owes more to chance than to an organized progression to supremacy. He starts with bipedality, which he shows could have arisen entirely by accident, as a by-product of sexual selection, moves on to technology, large brain size, intelligence, language, and, finally, sentience. He reveals each of these attributes to be alive and well throughout the animal world--they are not, indeed, unique to our species.
"The Accidental Species "combines Gee's firsthand experience on the editorial side of many incredible paleontological findings with healthy skepticism and humor to create a book that aims to overturn popular thinking on human evolution--the key is not what's missing, but how we're linked.

Rage of Stars is the climactic third volume of The Sigil, Henry Gee's epic tale that explores the nature of humanity, religion and love. Praise for THE SIGIL TRILOGY: "Great stuff. Touches of Douglas Adams, Barrington Bayley, David Britton and Steve Ayelet only emphasise the splendid originality of this book. Henry Gee is thoughtful, funny, original. And pretty thoroughly mind-expanding in the tradition of Wells, David Lindsay, Stapledon and Clarke. In fact everything you yearn to find in a very good contemporary SF novel. Really enjoyed it " -SFWA Grandmaster Michael Moorcock "Coming to a science fiction novel by Henry Gee I was expecting a work knowledgeable about the world and all its ways, but who would have guessed it would also reveal Henry to be a visionary space voyager of the first order? The Sigil is in the grand tradition of Stapledonian space opera, and provides not only an explanation for why this universe is the way it is, but gives us the many vivid wild adventures on the part of some (very appealing) conscious characters acting to make it that way. Awesome stuff, and a true pleasure to read page by page." -Kim Stanley Robinson, award-winning author of Red Mars "Fast-moving, insanely inventive science fiction in the grand manner-seldom has the fate of the galaxy been handled on such a large scale. Gee draws on archeology, geology, physics, and biology to create a rich tapestry with surprises woven into every thread." -Nancy Kress "Siege is compelling, grandiose, and breathtaking in its spacetime and its characters are intriguing, personal, and complex....This book of Henry's is going to be high on the charts." -scienceblogs.com "Echoes of Olaf Stapledon and Arthur C. Clarke, with more interesting characters than either of them." -John Gribbin "Cosmically deep and sensually rich, here is a very warm, enthusiastic and human book about great issues of our own world and of the whole universe, beautifully written. What can I say but: Gee Whiz (unless somebody already has...)" -Ian Watson "One of the very best books I've ever read." -Critique.org "Henry Gee serves up a tasty stew of sex, science and space opera. Or should that read romance, rationality and retro-SF? Either way, the book is great entertainment." -Vaughan Stanger "A great very-wide-screen story, with many interesting characters I cared about...the writing-and the palaeontology-are beautifully executed" -Jack Cohen, author of Wheelers and Heaven "wildly imaginative... personalities and relationships drive the story forward as much as its grandiose scale, making "Siege" difficult to put down." -Alex Shvartsman "Henry Gee's crackling prose and fast-paced storytelling pull the reader right in, but it's the vividness of his characters that creates such a sense of intimacy in this large-scale cosmic tale. It's an impressive fiction debut, a page-turner that delivers the goods " -Mercurio D. Rivera, World Fantasy Award nominee
