Chitin poses a problem. And unless I can wiggle out of the problem, I am
stuck. One possibility is that calcium for animals is linked with the
electrical system in animals in that you cannot get the fast motion with
large mass unless it was calcium based. Chitin based is okay for tiny mass.

Not sure whether I can wiggle out of this.

One possibility is that there are 5 Kingdoms. One with a calcium framework
(animals of large mass) another with a carbon framework (plants), another
with a chitin framework (animals of small mass), and the last 2 with no
framework.

I wiggle out of the problem be calling low mass animals with chitin their
own kingdom.

This leaves the vertebrates without calcium in their endoskeleton, as wel as
the non-arthropod invertebrates (probably some others as well). Better get
ready to have 5 squared kingdoms?

I mean, in physics we have the 5 basic forces-- Coulomb, StrongNuclear,
WeakNuclear, gravity, and antigravity. So, I wiggle out of this jam by
giving the chitin animals their own kingdom.

Don't know if I like that solution as of yet.
