Newfound primate teeth take a big bite out of the evolutionary tree of life

Fossil hunters have found part of an ancient primate jawbone related to lemurs -- the primitive primate group distantly connected to monkeys, apes and humans, a researcher reports. Scientists named the new species Ramadapis sahnii and said that it existed 11 to 14 million years ago. It is a member of the ancient Sivaladapidae primate family, consumed leaves and was about the size of a house cat.
