How did primates get to Africa in the first place?

“We’ve heard of the ‘out of Africa’ theory of human evolution, but that’s recent history,” said K. Christopher Beard, a paleontologist at the Carnegie Museum of Natural History in Pittsburgh and an author of the journal report. “So there may now be the ‘into Africa’ problem.” That is: How and when did some primates finally make it to Africa, which was an island until as recently as 16 million years ago, to set in motion the emergence of the human species?

So other continents (particularly Asia) had primates long before Africa and they did nothing with them? These other places just made the same old dumb primate (worried about food, worried about predators, worried about fucking, not worried about why there are bright dots of light in the sky), and it took the geography and climate of Africa to make the kinds of brains we all enjoy today? The land of Africa is the mother of the deepest kind of thinking in our known universe. Without Africa, no Standard Model, no theory of evolution, no nothing on the moon.
