How did Monkeys get to South America?

As far as I can find out, the distance between Africa and South America during late-eocene/early-oligocene has been estimated as between 1000 km and 1750 km, with the distance today being 3200 km. As a comparison, the distance from the South American mainland to the Galapagos Islands is 970 km, which should give you some idea how close the continents were at this time.
Distances I got from this book on primate evolution, just click on 'preview this book' and scroll down to page 117. I think this may also have been where Dr Adequate got his illustrations from.As for the potential for island hoping, the volcanic activity in the area could have given rise to suitable islands. For example I found the island of Trindade off the brazilian coast. It lies on the eastern end of a chain of submarine volcanoes which extend 1000 km from the continental shelf.Also I am a bit confused on your position on this and Noah's Ark. You suggest in Message 20 that arguments by 'evolutionists' support the ark story yet you don't explain why. For example, why did the new world monkeys traipse over an entire continent and the modern Atlantic Oceans 3200 km when their old world relatives decided to stay put, especially considering the arguments you have brought up against rafting over a relatively more moderate distance? Do you accept genetic studies which suggest that old and new world monkeys split approximately 35 Mya, or do you think it is a result of this super-hypermutation on steroids thing?
