Animation of chimpanzee yawning from Emory University. Illustration from BBC News. I'm sure we are all familiar with this scenario: Someone yawns and we would "catch" it or vice versa. This is the phenomenon of contagious yawning. A new paper from The Proceedings of The Royal Society "Computer animations stimulate contagious yawning in chimpanzees" suggests... Continue Reading →

It's a National Geographic page about the Senegalese Fongoli chimps, named after the Fongoli stream that runs through the chimpanzee's range. There are videos showing these chimps using tools fishing for termites, hunting a bushbaby and... Continue Reading →
Humans Evolved From Tree Climbers
A research from Duke University by Daniel Schmitt, associate professor of evolutionary anthropology, and Tracy Kivell, a post-doctoral research associate, shows that human evolved from tree climbing ancestors, not from knuckle-walkers. Schmitt and Kivell examined and compared the wrist bones of humans and African apes. Their research, "Independent evolution of knuckle-walking in African apes shows... Continue Reading →
Nakalipithecus nakayamai, a Miocene Ape from Kenya
The collective understanding of Miocene African primate evolution, especially ape evolution, is generally unfounded. Why? Because the fossil record is spotty, there are only a handful of primates from the Miocene. The Miocene lasted from 23.8 to 5.3 million years ago, and a lot of interesting things happened in the ape lineage during that time.... Continue Reading →
A New African Miocene Ape: Nakalipithecus nakayamai
In August, 2007 Gen Suwa and crew reported on a new Ethiopian Miocene Ape, Chororapithecus abyssinicus. And today, Kenyan and Japanese paleoanthropologists have published their study of a fragment of a mandible and 11 teeth, dating back to between 9.8 and 9.88 million years, which was found 2005. The fossils were unearthed in volcanic mud... Continue Reading →
