Just like early humans Savannah chimpanzees, which can make weapons to hunt other primates for meat, do also seek refuge in caves. New findings suggest the chimps apparently shelter themselves in caves to hide from the extreme African heat. Primatologist Jill Pruetz at Iowa State University in Ames and her colleagues, researching on savannah chimpanzees told that these dwell in environments much like those from which the stone-age people once emerged.
The researchers investigated specifically the Fongoli community of 35 savannah chimpanzees in southeastern Senegal, one of the hottest and driest habitats chimps live in today. Pruetz and her colleagues recently found that Fongoli chimps apparently could make spears to hunt  other primates, such as Bush-babies.
Pruetz recalled that finding the chimpanzees in their large, roughly 7,400-acre home range looked just very challenging at the first sight. She told science Live-Science, "Going for a week or 10 long days without seeing chimps was very normal at the beginning and, as you might imagine, very frustrating at times, especially during the dry season, when heat is such an issue for chimpanzees and humans alike!".
