Conclusions • Man has traveled on water for 70,000 years. • Record from before ice age. • Evidence: Genetics, artifacts. • Many antique ships found recently. • Past developments ‘rediscovered’. • Good planning = good sea eating • Floating uses less energy than walking. • Early ocean migration was eminently doable.

A way out of Africa • In 70,000 BP man was in danger. • We know via Genetics That he went north and east out of Africa. • Maybe from Djibouti to Yemen on reeds or skin floats.
A way out of Africa • Maybe across the Red Sea on reed floats. • Archeological evidence of human habitation has similar dates from Middle East and maritime Asian Pacific.
