10.  How did the rabbit population change?

11.  Describe the conditions that could have lead to the changes seen in the rabbit population.

12.  What is extinction? Why does it happen to some organisms? What types of organisms would most likely go extinct in a rapidly changing environment, the generalists or specialists?

13.  In a given population, why are some traits seen more often than others? Why would/could these traits change in future generations?

19.  Describe how life has evolved from the very first organism? (in terms of complexity and diversity).

20.  When looking at different rock layers, where (which layer) would you expect to find the oldest organisms? The youngest organisms? The least complex? The most complex? The least diversity? The most diversity?

21.  What types (changing or stable) of environments would not show rapid evolution in the populations of species living there? Which environments would show rapid evolution of the same populations?
