Modular Person

The Modular People were a posthuman cell-colonies that evolved from the Colonials.

The core of the modular people were a species of specialized sapient colonials whose function was to direct other specialized colonials. They spread across the planet and adapted other colonial colonies to work under their control. Thus they formed the civilization of the modular people.

Eventually, the Modular People built industrialized mega-cities. Every "individual" was a colony formed from groups of different colonials, with each colony being designed for their purpose. Also, they could split up and form new individuals from their "cells". The only thing constant in all of their protean existence was their mental and cultural unity.

Modular People society was an utopia of equality where everybody was happy to be a part of the whole.
