CM Kosemen
C.M. Kosemen (also known as "Nemo Ramjet") is a Turkish author, paleoartist, and speculative biologist best known for All Tomorrows: A Billion Year Chronicle of the Myriad Species and Varying Fortunes of Man (2006), a landmark work of Speculative Evolution that chronicles a hypothetical billion-year future of post-human evolutionary divergence. A professional paleoartist and collaborator with academic paleontologists, Kosemen is internationally recognized in both the scientific illustration and speculative biology communities.

All Tomorrows
All Tomorrows follows the descendants of humanity from the near future to approximately one billion years in the future, depicting how terrestrial humans colonize space, are conquered and genetically altered by an alien civilization called the Qu, and subsequently diversify into hundreds of radically different post-human species adapted to various planetary environments over hundreds of millions of years. The book is notable for:
- Applying real evolutionary biology principles (convergent evolution, genetic drift, isolation, adaptive radiation) to speculative futurism.
- Exploring the philosophical implications of radical posthuman divergence, including sapience, memory, cultural continuity, and what it means to be human across geological time.
- Functioning as both hard science fiction and a meditation on extinction, survival, and identity.
The work is frequently cited as a standout example of the Speculative Evolution genre and is recommended by UAP Gerb as an entry point for thinking seriously about what extraterrestrial biology might look like.
Other Work
Kosemen has collaborated with paleontologist Darren Naish on books reassessing the plausibility of cryptozoological creatures if they were to exist as real biological organisms (Hunting Monsters, 2016 with Naish and John Conway). He also co-authored All Yesterdays (2012) with Naish and John Conway, which challenged overly conservative conventions in paleoart.
