Great Apes May "Know About Knowing"
A recent study discussed in Science Daily suggests great apes are aware that they can be wrong when making a choice. In the study, 7 captive gorillas, 8 chimpanzees, 4 bonobos and 7 orangutans were presented with 2 tubes, 1 empty and 1 with food inside.
Gorillas Eat Meat Too?
Jane Goodall first documented that wild chimpanzees occasionally hunt and eat small mammals. Now, there's evidence raising the possibility gorillas also eat small vertebrates such as monkeys and antelope -- but the researchers involved say more study is needed. The study was intended to examine bonobos' meat-eating habits, using gorillas in Loango National Park in Gabon as a control. The evidence showed animal DNA infeces of both control and study groups.
