A study by scientists at the University of Nevada pesents evidence that Neanderthal may have sailed the Mediterranean Sea. Tools in deposits that could date back 170,000 years were discovered on Crete. There is the possibility, however, that early hominins arrived on Mediterranean islands as a result of having been swept to them while hanging on to logs. Notwithstanding, per the article:
"They had to have had boats of some sort; unlikely they swam," said Alan Simmons, lead author of a study about the find in this week's Science. "Many of the islands had no land-bridges, thus they must have had the cognitive ability to both build boats and know how to navigate them." ....On Crete, for example, tools such as quartz hand-axes, picks and cleavers are associated with deposits that may date to 170,000 years ago...."Additionally," he continued, "findings from the Indonesian Wallacea islands suggest the presence of hominins as early as 1.1 million years ago on Flores Island."
The study has been published in this week's edition of the journal, Science.
