Why were there hunter gatherers?

Hunter-gatherer cultures forage or hunt food from their environment. Often nomadic, this was the only way of life for humans until about 12,000 years ago when archaeologic studies show evidence of the emergence of agriculture. Human lifestyles began to change as groups formed permanent settlements and tended crops

- "the past is made of multitudinous items ranging from anything that can be collected, recollected or assessed to originate in the past. as such, the past is a gallimaufry of particulars that may not have been related in any way. however, the human mind seeks organization to understand concepts and other things. the human mind therefore seeks relationships in explaining and studying the past. history being a humanity, dictates that historians have to serve this human trait by bringing structure to details of the past. historians do this by creating interpretive frameworks that capture as many details as possible."
