Homo Erectus, Guys, Not HSS

Some of these rafts were recorded to have carried live animals all the way across the Indian Ocean to Africa.

I'd like to see the source for that one.  What would they have eaten on the way?

Yet some old world monkeys evidently drifted all the way across the Atlantic to South America to become ancesters of new world monkeys on mats of vegetation.

Or they were carried across the relatively narrow passage between Africa and So America by boat-building HE.  The winds and currents are perfect for an east-to-west crossing....although the return trip would be pretty damned hard.
