Let me suggest a peek at “microtubules” as an integral part of biological intelligence.
I believe this self-organizing nano-scale dipolar coil which is a “common denominator” in ALL Eukaryotic lifeforms and is the most important cellular information processor, carrier, and communicator in all biological life sustaining functions.
Microtubule
Intracellular organization
Microtubules are part of the cytoskeleton, a structural network within the cell’s cytoplasm. The roles of the microtubule cytoskeleton include mechanical support, organization of the cytoplasm, transport, motility and chromosome segregation.
In developing neurons microtubules are known as neurotubules,[23] and they can modulate the dynamics of actin, another component of the cytoskeleton.[24] A microtubule is capable of growing and shrinking in order to generate force, and there are motor proteins such as kinesins and dynein that allow organelles and other cellular components (such as mRNA) to be carried along a microtubule, using specific adaptor proteins [25] [26].
This combination of roles makes microtubules important for organizing and moving intracellular constituents/cargo.

When you came back you picked my favorite subject “microtubules”
This incredible little dynamical nano-tube consisting of just 2 tubulins perform an astounding array of sensory information transport throughout the body and brains at all stages of evolution, from slime molds to humans.
