1. Even Alfred Wegener acknowledged that the apparent fit of continents or "matching” of continental coastlines was crude at best. Propose an explanation for this inexact fit. 2. Evolution is adaptation, or change, of organisms in response to environmental changes. The theory of evolution states that similar organisms evolved from a common ancestor. Scientists hypothesize that marsupials like koalas and kangaroos, which are native only to Australia, evolved from the same ancestor as the marsupials known as opossums, which are native to North and South America. Does the theory of plate tectonics support the theory of evolution in this case? Explain your answer.

3. About 200 million years ago, extensive tropical swamps existed in North America. At the same time, glaciers covered southern Africa, southeastern South America, much of India, portions of Australia, and nearly all of Antarctica. How does this information support Wegener's idea of continental drift?
