The Ugalla region of western Tanzania is a dry woodland savanna and home to chimpanzees
that apparently use tools to dig up the underground storage organs of plants
for food. The tool-using behavior may parallel the behavior of early hominids
who left the forest for the African savanna five million years ago, according
to University of Wisconsin-Madison anthropology professor Travis Pickering.

Pictured are sticks used as tools by savanna chimpanzees to excavate underground
food resources. Tool-wielding savanna chimps of western Tanzania used these sticks
to crack a tough layer of soil to excavate the underground storage organs - tubers,
roots and bulbs - of plants as a food resource. The behavior by chimps to excavate
underground food resources with tools has never been documented before, according
to University of Wisconsin-Madison anthropologist Travis Pickering, and may resemble
behaviors of the earliest hominids as they migrated from the forest to the African
savanna five million years ago.
