Neanderthal Sailors

Humans have been sailing since 50,000 years ago, but it now looks like Neanderthals were able to set sail 100,000 years ago. Their tools were discovered on some Greek islands. At first it was thought that the sea level must have been low enough back then to allow land passage, but now scientists have determined that even though the sea level was much lower, it was not low enough to let Neanderthals get to those islands without a boat.
