Three Dollar Quill

Wow, I really played myself by putting the full title in the filename, huh.

Anyway, I'm slowing narrowing down what I expect out of the spec-evo side of this project. Triploblasty seems reasonable, closely replicating the evolution of the spinal cord does not. The selection pressures associated with cephalization currently seem to me to be weaker, which is not the same as absent. Unsure what kind of jaw structure is plausible. I've got some weird ideas about manipulatory appendages that I don't know if they make sense. The idea being to have hand-like structures, and those have bones, but the "arms" have inflatable hydraulic chambers instead of bones, allowing them to switch between "flexible arm movement for propulsion" and "fine motor control and high leverage for manipulating objects". Probably need bones at the joints between chambers. As I said, not sure if this all makes sense. I don't know if it would plausibly evolve even if it did make sense in terms of fitness.

Anyway, I don't want to think about it any more tonight.

Good night.
