Life Cycle
They are 'born' (often it is hard to pinpoint exactly when), grow, and eventually die.Size
Some are large and important -- countries, cities, towns, multinational businesses. Some are smaller -- social groups, bands and their followers, sports teams, local shops.Problematic components
They have an immune system for when individual members become detrimental to the group: perhaps a police force, or some sort of ostracising mechanism. Examples.Evolution
They exchange ideas, often through recordings -- writings, audio and video, meetings between delegations. "Memes".The Take-aways
Diverse groups of people are a good thing: evolution doesn't work with too few different individuals.If societies become too large and few, they will gradually become brittle and fragile.
Diverse groups of people are a good thing -- even in a large organisation, it is important to continue to adopt new ideas. Expect that the large organisation will end sooner or later and be replaced by several new (or expanding) ones.
Also, in large societies, ostracising mechanisms don't work very well. Stick up for people when they are being douchebagged.
