Throughout Africa, small groups of primate species have been able to forge out an existence and in some cases remain isolated to avoid being discovered by the scientific world as a new species.
In this episode Jean looks at the problems facing primates in Africa through habitat destruction. He travels to Mahale Mountain where one of the largest populations of chimpanzees can be found to look at the pressures facing one of our closest living relatives.
From there he travels to Udzungwa N.P. which is considered one of the world greatest bio-diversity hot spots, and is home to two newly discovered monkeys.
