Multiple Choice

There is much debate among scientists about when,where,and how anatomically modern humans achieved behavioral modernity.Some researchers suggest that about 50,000 years ago a genetic mutation acted to rewire the human brain,allowing for an advance in language and other related modern behaviors.Others propose

• A) that drastic climatic changes 40,000 years ago led archaic humans to turn to ritual-a definite sign of behavioral modernity-to explain the unforeseen environmental changes that suddenly altered their way of life.
• B) that the advent of the nuclear family within larger nomadic groups made possible intense social interactions that triggered more complex social behaviors.
• C) a culinary hypothesis, suggesting that Homo's capacity to increase the range of foods in the diet triggered the necessary brain development to make modern behaviors possible.
• D) that instead of a sudden event in Europe due to a mutation, behavioral modernity resulted from a slow process of cultural accumulation within Africa, where Homo sapiens became fully human long before 40,000 years ago.
• E) a hearth hypothesis, suggesting that the most important trigger to behavioral modernity was Homo's capacity, achieved 50,000 years ago, for manipulating fire and thus living in caves and cooking their meat.
