Speculative Biology
Speculative Biology
Invent alien life that evolves by real biological rules.
Most of the work happens in notebooks and tab-stacks: you sketch a six-limbed grazer, then realize its metabolism can't support that mass on this planet's gravity, and start over.
The thrill is the moment a creature finally clicks into a coherent ecosystem.
The friction is that nobody else sees the years of evolutionary logic behind one drawing, and the rabbit holes of real biology will eat whole evenings.
Fit
Is this for you?
Honest tradeoffs before you spend money or clear space.
You'll enjoy this if
- Like redesigning a creature once you realize its metabolism can't work.
- The moment a creature clicks into a coherent ecosystem is enough payoff.
- Rabbit holes into convergent evolution and metabolic scaling sound fun.
Not for you if
- Nobody seeing the years of logic behind one drawing would deflate you.
- Want a tangible result, not notebooks and tab-stacks of evolutionary logic.
- Starting a design over because the biology doesn't hold would frustrate you.
