Scientists unearth resident of the "lost world"

Scientists have discovered a tiny species of ancient human that lived 18,000 years ago on an isolated island east of the Java Sea - a prehistoric hunter in a "lost world" of giant lizards and miniature elephants.

These people stood 3 feet tall and had heads the size of grapefruit. They co-existed with modern humans for thousands of years yet appear to be more closely akin to a long-extinct human ancestor.
