World's Oldest Fish Hooks Show Early Humans Fished Deep Sea

The world's earliest known fish hooks reveal that humans fished the open sea for much longer than previously thought.

Past studies have revealed that early humans were capable of crossing the open ocean as far back as 50,000 years ago, such as they did to colonize Australia. Until now, however, evidence that such mariners could fish while in the open sea dated back only to 12,000 years ago.

"In most areas of the world, evidence for our early ancestors' coastal exploitation is now submerged — it was drowned by rising sea levels," researcher Sue O'Connor, an archaeologist at Australian National University in Canberra, told LiveScience.

Now O'Connor and her colleagues have found evidence of prehistoric fishing gear and the remains of large fish such as tuna at a cave shelter known as Jerimalai, located in the Southeast Asian island nation of East Timor.
