Our ancestors not only fished rivers and the coastline. They caught marine food in the deep ocean. It is known that people travelled across oceans 50,000 years ago. However, proof that they could catch fish in the deep sea went back only 12,000 years. New evidence shows that Man ate fish from the ocean further back than 12,000 years. In caves on the island of East Timor remains of tuna and other large fish have been found. East Timor was "out of bounds" for paleontologists until recently because of the ongoing troubles with Indonesia. Information on ancient Man is changing scientific knowledge about our ancestors. Bone fish hooks dating back 42,000 years have been found there. The diet of early Timorese was varied. It included birds, rodents, bats, snakes turtles and fish. Few large animals lived there. Half of the fish found were tuna, a fast moving fish that would have taken great skill to catch. Using nets was the only way, so they had an advanced culture. http:/
