A 1.4 million-year-old fossil jaw belongs to a previously unknown human relative from southern Africa, a new study finds.
The extinct human relative is from the genus Paranthropus, whose nickname is "nutcracker man" because of its massive jaws and huge molars. However, the newfound Paranthropus species has a more diminutive jawbone and teeth, indicating that the nutcracker moniker might not be so apt after all.
