"Between 400,000 and 200,000 years ago, hominins are also known to have crossed to at least two islands in Europe, Corsica, and Sardinia. This is soundly demonstrated, but in addition it is possible that much earlier they managed to cross the Strait of Gibraltar. Unfortunately, that cannot be proved conclusively, because the alternative of reaching Europe by land has always existed." -- Robert Bednarik
