Why is hunter gatherers so important?

I am not quite sure what you are asking but a couple weeks ago i was learning about the indians of Texas and the are mostly important because this was how they got food.they were considered the most well advanced of all the natives because they were exelent farmers and hunters too! they ate many things like corn,squash,buffalo and small game.(small game means small animals like rabbits and squirrels.) i hope i answered your question in one way or another:)
