Hi All.

    When was the Strait of Gibraltar dry land? It's a shallow area which
dries up regularly, resulting in regular periods when the Mediterranean, or
much of it, also dries up. If my memory serves me right - I don't have any
reference on this to hand - it was dry during the glaciations, when sea level
was significantly lower than today. In that case bees would have been able to
cross from Africa to Spain a few thousand years ago, on the same basis as
they crossed from continental Europe to what is now Britain, across what is
now the English Channel and the North Sea.
