Last week we discussed the extinction of the megafauna at the end the Pleistocene epoch. Your assignment is to write a short essay (700 – 1000 words) that summarizes the required readings and lecture material from Week 3 and includes the following:
What were the megafauna? When did they likely go extinct? Give some examples megafauna that did and did not go extinct.
What were the potential causes of this extinction event? In answering this question, briefly summarize the three main hypotheses – (1) overkill, (2) climate change, and (3) the Younger Dryas Impact hypothesis.
For each hypothesis, include a critical discussion of specific evidence that supports and challenges each hypothesis.
As discussed in lecture, each of these hypotheses has weaknesses. What new evidence or research might strengthen or falsify each of them?
Provide a critical synthesis of what you think is the most likely cause, or mixture of causes, given current evidence.
You must cite and discuss at least one of the recommended readings in addition to each of the required readings(note that this does not include the websites to explore or Chapter 1 from Oregon Archaeology).
