There will also be some questions asking you to identify the kingdom, phylum or class (vertebrate classes) of organisms based on views of them in Kodachrome slides, drawings or written descriptions.

Possible short answer questions:

16.  List five major evolutionary events in order (any five that we have regarded as being important).

17.  Describe the changes in the general position of the continents from the early Paleozoic to present day, giving approximate time for each "arrangement or change" in millions of years before present.

18.  What event(s) caused there to be three major Eras in the Phanerozoic Eon?

19.  Name one group of organisms whose evolutionary history (and distribution of fossil forms or present-day relatives) is explained in part by an understanding of past continent movements (continental drift) and explain what aspects of continental movements were involved in the distribution of those organisms.

20.  Give two examples of close mutualistic, parasitic or coevolved associations between groups of organisms:  of each name the group and its phylum for each of the associates and give the benefit or harm to each of the associates.
