Lee Rannals for redOrbit.com - Your Universe Online Chimpanzees rely on their long-term memory when searching for food throughout the rainforest, according to a new study published in the journal Animal Behavior.

People don't always do as their neighbors do, and the same is true of neighboring chimpanzees. That's according to a report published online on May 10 in the Cell Press journal Current Biology featuring observations of wild chimps as they used hammers to crack nuts.

German scientists say they've determined wild female chimpanzees copulate more frequently with males who share meat with them over long periods of time. Max Planck Institute for Evolutionary Anthropology researchers Cristina Gomes and Christophe Boesch said their findings strongly suggest that wild chimpanzees exchange meat for sex and do it on a long-term basis. Males who shared meat with females doubled their mating success, whereas females who had difficulty obtaining meat on their own...

The few remaining chimpanzees are now highly fragmented, with only one viable population living in Taï National Park, according to a report in the October 14th issue of Current Biology, a Cell Press publication. This alarming...

DAKAR, Senegal -- Conservationists say the dreaded Ebola virus along with decades of hunting and logging are putting some ape species on the brink of extinction in Central Africa. Ebola, which kills through massive internal bleeding, has long been known to infect primates in Africa. It was first identified in 1976 and has since killed about 1,000 people, some of whom are believed to have contracted the disease by consuming or handling infected meat from wild animals. Most at risk are...
