NOVA presents an exclusive new investigation into the sensational discovery of the bizarre ancient bones of the so-called Hobbit unearthed in a cave on the island of Flores, Indonesia. No more than 3 feet tall when fully grown, these tiny humans survived in the cave for tens of thousands of years, hunting the huge and fierce Komodo dragons that roamed their remote island home. In Alien from Earth, NOVA explores the latest evidence in a furious scientific debate on what the Hobbit bones represent. Are they the remains of a dwarf race of modern humans suffering from a strange disease? Or are they the unique and tantalizing testament to a previously unknown branch of the human family?
