  • The moment a creature clicks into a coherent ecosystem is enough payoff.
  • Rabbit holes into convergent evolution and metabolic scaling sound fun.

Before you commit

Cryptozoology

  • Wanting something real while honestly debunking it would frustrate you.
  • Most leads dissolving into misidentified bears would feel like a letdown.
  • You want fieldwork, not hours reading sighting reports at a desk.

Speculative Biology

  • Nobody seeing the years of logic behind one drawing would deflate you.
  • 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.
