I absolutely love this way of thinking. We assume that an "individual" is a single human being, because it's convenient and I guess because that's how our sentience works. But realistically, the body itself is an extraordinarily complicated mass of "human" cells often at odds (see a cake, one part of the brain say "eat it," another says "dude no you'll get fat"), and thats without considering the masses of "non-human" entities, such as gut bacteria, skin bacteria, etc.

And then we can go macro - a tribe can subdivide into gatherers, warriors, and crafters. A city can specialize further. A country even further. Imagine how different the life experience would be if humans existed as single entities alone in endless fields.

Then it gets even more fun to consider interactions with other lifeforms - dogs, plants, cows.

Man, what a cool field of research. I'm glad to hear people are studying this.
