    Review Questions

    • What physical and cultural features are unique to archaic Homo sapiens? How are archaic Homo sapiens different in both physical and cultural characteristics from Homo erectus?
    • Describe the specific changes to the brain and skull first seen in archaic Homo sapiens. Why does the shape of the skull change so dramatically from Homo erectus?
    • What role did the shifting environment play in the adaptation of archaic Homo sapiens, including Neanderthals? Discuss at least one physical feature and one cultural feature that would have assisted these groups in surviving the changing environment.
    • In your opinion, which of the hypotheses concerning the disappearance of the Neanderthals best incorporates the available evidence? Why?
    • What does the regional variation in archaic Homo sapiens represent in terms of the broader story of our species’ evolution?
    • Describe the issues raised by the discoveries of Homo naledi and Homo floresiensis in the understanding of the story of the evolution of Homo sapiens.
