Basically a person has the same role in a society as a cell does in your body as a molecule does in your cells.
They all run the same concept of a society.
99% of the people do all the hardwork to please the top 1%.
99% of the cells do all the work to please the top 1%, the brain.
99% of the molecules in our cells do all the work to please the top 1%, the nucleus
So whats next? The protons neutrons and electrons in the molecules work together as a society through forces to make a society.
Whats after that? Who knows as of yet. But maybe it can branch into forces.

We look at behavioral evolution as imitations, habituations and much more.
But if you think about behavioral imitaitons, isn't the stated above behavioral evolution and hierarchal evoluation?
We can see the same "society" in each level of complexity.
So whats next? Planetary? To our knowledge there is an infinite amount of space right?
Take all the planets we know and all the planets out there. Lets assume THERE IS something out there. Can we also assume there are MULTIPLE things outthere?
If we can assume multiple, can we also assume there are MANY other lifeforms? Even on the level of there being a whole new society?
A society in which the 99% of planets work to appease the top 1% planet which becomes the "boss"

Also another thing I would like to say is that as we look at the evolution in both directions, smaller and larger we cannot fathom what is on either side. The universe to us is infinitely big just because we cannot even fathom how large the universe is. We can also say that the universe is infinitely small because to our knowledge something always made up something. We just cannot fathom how small things go as of yet.

So when does this hierarchy stop? Basically the hierarchy will stop when the universe ends. But since we do not know when the universe ends, we cannot say when this hierarchy will end.

Lmk what you guys think, it might be extremely confusing but I am willing to explain.
