A fan made All Tomorrows family tree I fussed over quite a lot before settling on this version. It includes human lineages, other earthlings, and a few aliens. I did this mainly to add context to the book's family tree and organize some groups for clarity. And if you can believe it, this isn't even the whole roster of species, but I kept the well known species and their cohorts and ancestors in the picture as much as I could.
I found a lot of trouble trying to tie posthuman groups together with the boxes (miMind will try to attach them to the nodes because the boxes are just big nodes), and conveying the less obvious connections to some groups as indicated by the dotted lines. I'm aware there are more that should've been added, but, at a certain point I wanted to avoid added visual noise.
Now there's no way all the information thus far can fit into the ALT text feature, so it's probably best to take a crack at it here.
The very top starts with a non-human, therizinosaurs, to contextualize what Panderavis pandora is. Or, was. The green outline for these nodes indicates it's a reptile. I stuck it in the node closest resembling a coffin because Panderavis went extinct well before it was discovered.
The modern humans split off into two nodes, the Earth Humans, and the Martians. They had eventually interbred to create the Star People, who then discovered Panderavis bones.
The Star People hereafter had almost all populations genetically modified by the damselfly-like aliens known as the Qu, or Quhanim.
Under the posthuman lineages that died out during bottleneck events are: Mantelopes, Bone Crushers, Temptors, Hand Flappers, Blind Folk, Titans, Striders, and unknown others.
One lineage of Star Person went into hiding and avoided the Qu, which are the Spacers.
The surviving lineages that were Qu modified are:
Insectophagi, Ruin Haunters, Swimmers, Lopsiders, Colonials, Parasites and their Hosts, Worms, Finger Fishers, Flyers, Lizard Herders, Hedonists, and Predators with their Prey.
Note the Lizard Herders co-existed with a reptile originally from planet Earth, which had become the Herd Lizards. As appropriate, their outline is also green.
Onwards to the second empire era posthumans as indicated with blue fill and outline, with one notable green exception. Insectophagi gave rise to the Bug Facers, Ruin Haunters the Gravitals, Swimmers the Tool Breeders, Lopsiders the Asymmetric People, Colonials the Modular People, Parasites and Hosts the Symbiotes, Worms the Snake People, Finger Fishers gave rise to aerial species and the marine Sail People, Flyers gave rise to aquatic and terrestrial species along with the aerial Pterosapiens, Spacers became Asteromorphs, the Lizard Herders became Human Steeds, Hedonists turned Satyriacs, and the Predators became the Killer Folk. Prey still exist, but some of them are farmed.
And the one species that is considered arguably more human than the posthuman steed it coexists with, is the Saurosapients. They're descended from Herd Lizards.
The big box enveloping most of these posthumans indicates they were eradicated by the Gravitals, thus ending the second empire. Although most precursors went extinct in the sense they all evolved into their second era iterations, there is at least one exception. The Lopsiders still existed with the Asymmetrics, and were wiped out by their descendants. Only the Asteromorphs, Bug Facers, and Gravitals themselves remained.
The Gravitals then subjugated and modified the Bug Facers into the Subjects.
Meanwhile the Asteromorphs underwent further changes into godlike forms. They usurped the Gravitals, who were altered into the New Machines, and rescued the Subjects, who became the Rescued Subjects. The Asteromorphs, being hands-off parents of this new humanity, created Terrestrial forms of their kin to withstand gravity and watch over their Subjects on their home planets.
These are a few lineages left of what was once humanity, and an alien with an equally complex yet unknown history enters, the Amphicephali.
New Machines, Rescued Subjects, Asteromorphs, Terrestrials, and Amphicephali are indicated as coexisting in this new era with red.
The Qu descend from an unknown species, and the Author character's descent is equally mysterious.
And that about wraps it up. I've left out fan theories around the origins of the Amphicephali, Qu, and Author alien in trying to keep this chart objective to the original book. It may outdate itself once the redux is published, and there might not be a "need" for another fan chart if CMK includes one in the redux and polishes it to a shine. We'll see in a few years, realistically speaking.
