Of spears, chimps and early humans
Chimps have been observed hunting with spears, anthropologists reported, an unexpected addition to their known use of tools and a discovery with possible links to hunting by early humans. No chimps have been seen to hunt with weapons previously, says anthropologist Jill Pruetz of Iowa State University. The study published in the Journal Current Biology reports on the activities of chimps that live in a savanna region in Senegal, similar to sites where early humans lived more than 1.2 million years ago
