The biggest similarities between hunter-gatherer and agricultural societies have to do with the way that technological innovation transformed existing social and cultural practices, which also allowed for significant physical and intellectual development.
Because their stone tools and other improved techniques led to hunter-gatherers having more leisure time than the farmers who would eventually be tied by daily labor to the land, cave-dwelling people were able to develop a rich artistic tradition that suggests animistic religious belief and ritual. As stories were told around the communal fires, myths emerged that were passed down and remembered, and gods were created that became absorbed into later religious traditions. It is clear from some of the oldest known sites of human habitation that early humans had a profound urge to depict their known world in image and color with an eye for motion and natural detail that reflects a high cognitive function. As oral language developed among early humans so orders could be given and spirits praised, their brains enlarged, expanding their intellectual and imaginary capacities.
The improved food quality and nutrition that came with cooking also contributed to the physical and cognitive growth of humans that would allow them the strength and know-how to begin taming the land for farming.The communal interactions around the cooking and heating fire fostered increasingly complex social organization within hunter-gatherer societies, which was a precursor to the more sophisticated civilizations that developed around agricultural settlements.
While systems of writing were not invented until tens of thousands of years later, nor were temples built to appease the gods, culture flourished among the hunter-gatherers as inter-group exchanges increased in frequency and range of distance. The monuments to religions, wealth, and royalty that distinguished later agricultural city-states with their codification of tradition and law were unprecedented expressions human vision and capability that had been long-evolving in human beings since the breakthroughs of the hunter-gatherer era which accounts for nearly all of human existence.
