The body should be a representation of your data. You will be discussing your subject objectively through the grades of primate evolution while pointing out the modifications which occurred through time. The grades of primate evolution are as follows: Grade I-The Lemuroids; Grade II-The Tarsiers; Grade III -The Monkeys; and Grade IV-The Apes and Man (see chart in prior post). You should plan on devoting approximately 1 to 2 pages of discussion to each of the grades in primate evolution. Make sure you carry your discussion through to man.With each grade, begin by describing some general background and introductory information on that category of primate. Next, devote the remaining discussion of each grade to your specific research subject.
