by C. M. Kosemen
All Tomorrows isn't a story you read so much as a future history you absorb. C. M. Kosemen presents a sprawling, millennium-spanning chronicle of humanity's genetic drift and radical evolution after a catastrophic first contact. You'll follow our descendants through bizarre, often horrifying transformations, adapting to alien worlds and pressures, only to face new forms of oblivion. The experience is incredibly thought-provoking, almost unsettlingly detached, like sifting through ancient archives of a lost civilization. It's epic in its scope, yet intimately disturbing in its detailed biological horrors and the sheer bleakness of survival against an indifferent universe. This is for readers who crave deeply philosophical science fiction, enjoy contemplating humanity's ultimate insignificance, and are ready for a visually driven journey into post-human existential crisis.
If All Tomorrows left you pondering the vast, indifferent stretches of deep time and humanity's fragile place within it, we have more for you. These recommendations share Kosemen's unique blend of speculative evolution and existential dread. You'll find other sweeping chronicles of future human species like Olaf Stapledon's works, or detailed biological adaptations in Dougal Dixon's Man After Man. We've curated titles that explore the bizarre, sometimes horrifying, paths evolution can take, and the unsettling questions about what it truly means to be human when stripped down to biological imperatives.

As a primary inspiration for All Tomorrows, this sweeping chronicle details the future evolution of humanity over two billion years and eighteen distinct species. It shares the same detached, historical narrative voice and focuses on the radical biological and social shifts of our descendants.
by Dougal Dixon
This book is the closest spiritual sibling to All Tomorrows, focusing on speculative evolution and the bizarre physiological changes humans undergo to survive on a changing Earth. It features similar grotesque yet fascinating biological concepts and a documentary-style presentation.
by H.G. Wells
A foundational text in speculative evolution, this classic explores the divergence of the human race into the Eloi and Morlocks. It mirrors Kosemen's interest in how social class and environment can lead to radical, permanent biological changes in the human lineage.
This novel explores the rapid evolution of a non-human species on a terraformed planet alongside the desperate remnants of humanity. Fans of All Tomorrows will appreciate the detailed biological world-building and the vast, multi-generational scope of the narrative.

Taking the scale of speculative evolution to a cosmic level, this book describes the history of the entire universe and the countless alien civilizations within it. It matches the 'grand history' feel of All Tomorrows and its focus on the insignificance of individuals against deep time.
Presented as the sketchbook and journal of a 24th-century voyage to another planet, this book focuses heavily on alien biology and speculative ecology. Its blend of high-quality artwork and clinical descriptions will resonate with those who enjoyed the 'field guide' aspect of All Tomorrows.
by Larry Niven and Jerry Pournelle
This hard sci-fi classic features an alien species that has evolved into specialized biological castes, much like the various human offshoots in All Tomorrows. It explores the terrifying and logical extremes of biological adaptation and population pressure.
Butler’s work often deals with the visceral, sometimes disturbing realities of biological symbiosis and human adaptation. These stories capture the same sense of 'biological horror' and the loss of traditional humanity found in Kosemen's work.
This novel follows the arc of human evolution from our shrew-like ancestors 65 million years ago to our ultimate, unrecognizable descendants hundreds of millions of years in the future. It shares the same 'deep time' perspective and unsentimental view of extinction.
by Brian Aldiss
Set in a far-future Earth where the sun is dying and plants have evolved to fill every ecological niche, this book features tiny, devolved humans struggling to survive. It matches the surreal, imaginative, and often grotesque biological creativity of All Tomorrows.
