A few centuries (millenia) back we as humans were organized in patriarchaic clans. We changed from nomadic hunters to farmers and settled down. The discovery of fire allowed for a different sort of living, we started to cook, to forge weapons, to build villages and cities.
The invention of writing allowed us to preserve and teach knowledge beyond the local oral traditions.
Eventually this made it possible to create states and nations where the members having diversified their skills need each other to live, that means people gave up on autonomy but got overall higher wealth and possibilities.
This then got more efficient through capitalism, with more work-specialisation, with a paper-currency, with banks...
And coupled with new inventions like the steam-engine, electricity, radio... allowing for bigger societies, more comfort, more wealth... more security... that then allowed even women to participate in earning their livelihood.
Family-structures changed considerably from patriarchaic clans to the modern small family-structures with a mother, father and one-three children.
And it doesn't stop there, even this nucleus family-structure is changing.
To be continued...
