^ I believe that the kakuhou is basically a "hive" for the rc-cells which are the parasitic lifeform that has infected all of humanity. (the majority of all parasites (80%) are single-cell organisms capable of infecting any kind of cell and then reproduce like a virus. The rc-cells are present in All humans, just in different amounts, and fit the common parasite norm)

There´s a lot of real-life parasites that alters the behavior of their hosts, The rc-cells are no different since their command is "cannibalize" on other rc-cells.

It´s essentially a single bio-dome species that feeds of others of their kin. regardless if it´s "human" or "ghoul"

The "kagune" is, in my theory, just a "colony" of rc-cells, forming a structure like the "Portuguise Man O´ War" is not a single organsim, but a colony of million tiny ones that creates this jellyfish like structure for the sake of mobility and predation to get food for the colony (it eats anything that gets entangled in the tentacles, they too made from thousands of units working together as a single one)

When two ghouls clash with their kagunes, it´s essentially two hostile "rc-cell colonies" that´s trying to either "Eat" the other or "Defend" their host. The Kagune was made to fight other ghouls after all.

The more rc-cells that´s entering a host, the more "hives" (kakuhous) are made to house all these parasites safely.

The kakuja is basically the colonies of rc-cells starting to invade the host´s brain, gaining their own sentience in the process. (Centipede the first time used three different honorifics to refer to itself, Rize´s: due to the original colony in Kaneki coming from her, Yamori: Due to the kakuja colony which already started to gain his sentience entered kaneki´s body and reformed its colony inside his body instead. And Kaneki Ken: Who was the host his rc-cells now started to gain another form of sentience from)

We know that the ghouls have existed for a long time, so it´s safe to assume that the rc-cell parasite has existed just as long as well and evolved to ensure the survival of the host. Evolved to ensure their own survival and making the differences between "human" and "ghoul" bigger and bigger.

Kanou´s failed experiments died from overexposure to the parasitic rc-cells, the immune-systems went high-wire and killed the hosts in the process as the kakuhou colony began feasting on their rc-cells instead, being rejected by the immunesystem and acknowledged as a "alien entity" in the body.

Ghouls are just humans with a higher tolerance to the parasitic infestation of the Rc-cells than "normal" humans are.

ROS are just what happens when the parasites forms a colony in a human being that doesn´t have that kind of immunesystem... (The kagune tumor in Haru´s face for example, showing that the colony can start growing anywhere near the brain as it´s usually located next to the spinal cords in ghouls.)

The only real difference between Ghouls and Humans, is that the "ghouls" are people with a evolved immunesystem that can counter the parasite infection and even weaponize it.

That´s how I see this topic anyway.
