Describe the supercontinent-cycle hypothesis.

Answer both of the following questions. Describe the supercontinent-cycle hypothesis. Explain how this phenomenon might affect ecological and climatic changes. Discuss possible animal and human reactions. Develop and present your position on the theory, and offer an alternative hypothesis. Explain the African fossil record. Develop a position as to its importance, validity, and historical influence. Offer evidence to support your position. Answer each question completely in a carefully prepared essay of 200-400 words (one to two typed, double-spaced pages). Do not merely copy sentences or paragraphs from your reading; instead, give your own analysis and, when necessary, refer to passages you have read. When you do quote or paraphrase a passage, be sure to acknowledge the source. When you have completed your assignment, proofread your answers for correct grammar, spelling, punctuation, and so on.
