LOS ANGELES - New research suggests humans were expert deep-sea fishermen as far back as 42,000 years ago, hauling in tuna, sharks and barracudas.
The latest evidence comes from an excavation on the southeast Asian island of East Timor where remains of tuna and other deep-water fish were uncovered inside a cave. Using dating techniques, a team led by archaeologist Sue O'Connor of Australian National University found what is the earliest evidence for ocean fishing.
The findings were reported in Friday's issue of the journal Science.
Since catching tuna and marine fish requires tools and advance planning, this meant people must have developed the mental and technological know-how to exploit the sea.
