Early humans fished deep seaPARIS: The world's earliest known fish hooks reveal that humans
fished the open sea for much longer than previously thought,
science journal LiveScience reported.
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.
Their discovery uncovered fishing hooks made from bone that date back to
about 42,000 years ago, making them the earliest definitive evidence of such tools in the world.
"It is possible that people caught the tuna in the deep channel that lies
off the coast of the Jerimalai shelter," O'Connor said.
