The chimpanzees of Fongoli in Senegal are some of the most interesting chimps in the world. Their habitat is largely grasslands and to adapt to these conditions they behave in a very different way from most other chimps. They are more bipedal (they walk upright) than any other chimp group and they have even been seen to use 鈥渟pears鈥� to hunt smaller primates. Jill Pruetz is the primatologist who studies them 鈥� she believes the Fongoli chimps are important for shedding light on how the ancestors of humans changed as they left the forests and stepped out onto the savannah grasslands.
