43 years ago, a group of chimpanzees that were once living peacefully in Tanzanias Gombe Stream National Park suddenly split in two — one in the north area of the park, and the other in the south. This turf war went on for four years, and was chronicled by Jane Goodall, who has spent more than 50 years in the park during her storied primatology career. She kept tabs on this conflict during her observations, something thats now being reevaluated with the help of social networking software, NewScientist reports.
