Palau is a remote chain of islands in the Pacific Ocean.
When National Geographic scientist Lee Berger visited the islands, he heard rumours of a possible discovery of fossilised human remains.
Berger, a paleoanthropologist responsible for many ground-breaking discoveries about early man, set off to investigate.
Were these the remains of a local hunter? A soldier from one of the many battles fought on the islands during the Second World War, or something completely different?
