Monkey travel in evolution (Introduction)

DAVID: The relationship between African and South American monkeys appears to be established, but how did the monkeys originate in Africa and get to South America. The current theory is they crossed the ocean, but how? They would starve on drifting raft travel.

Is it beyond the realms of possibility that (a) fossils may one day be found that date back to when Africa and South America were one land mass, and/or (b) that the dating of continental drift is wrong? I'd find either of those explanations more convincing than a load of raft-building transoceanic monkey-explorers.
