At least this item identifies a key issue. all multicellular organisms on earth consist of a finite number of what we call organs. This includes bone(s) and skin My big take home is that the number of these organs are both finite and deeply conservative. Between the bone organ and the skin(exoskeleton) organ we manufacture all complex life on earth.
From this and a handful of other organs like muscle and the nervous system we have most of it. again this is a small finite number of organs all evolved once and then used over and over ad infinitum. with that tool kit, the rest of evolutionary develoment took place.
What needs to strike home though is just how conservative this all was. i share organs with every critter out there on land and on sea. Nature looks like a drama queen at times, but it just is not so. Imagine every organ as a specific sub routine which can be adjusted to needs.

Beetle toxic punches help reveal how new types of cells develop and co-evolve to create organs. These mechanisms can be applied to the more complex organs of animals, including humans.
The fundamental challenge facing multicellular animals is how to coordinate different cell types so that higher levels of function, such as organ function, emerge from their interactions.

Many organs …
