Fishermen May Have Found Unknown Human

Fishermen in Taiwan discovered a fossilized jawbone that may be evidence of an undiscovered group of primitive humans. The bone, labeled Penghu 1, resembles a previously discovered 400,000-year-old specimen. Scientists wonder if the two of them come from an unclassified species of humans or add further credence to the belief there are multiple lineages of humans that may have existed in Asia before the modern species arrived in the area around 40,000 years ago.
