Here is a question about this article: Hunting-gathering was the common human mode of subsistence throughout the Paleolithic, but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples.
What is the answer to this question: How do modern hunters and gathers differ from early ones?
