Tens of millions of years ago, plate tectonics set North and South America on an unavoidable collision course that would change the face of the Earth and spell life or death for thousands of species. Juan D. Carrillo explains the massive biological repercussions of this collision, which caused one of the greatest episodes of biological migration in history: The Great American Biotic Interchange.

Colliding makes it sound like it happened quickly. But it did not. First 9fnthey would have gotten close to knew another. Birds would have flown between them, then closer, small animals would have been able to cross on debris from things like storms, then closer animals would have started to walk over any ice that bridged them depending on region. Then closer animals that could swim would have been able to cross. And the closer they would have been connected when the sea ebbed, but been separate when it flooded and gradually this would have increased until it never flooded again.

Americas history would also be very different since their would have been a waterway to get to India past North America making then a huge political tool since Britain at the time had control of trade routes from Egypt and Iraq, India being huge exporter of spices, all together avoiding the expensive costs of going around Africa and possibly, along with Spains colonial efforts in South America, would have made Spain a global super power

This is idiotic. The continents are landlocked nowand always have been. Absolutely no evidence to the contrary, except in the minds of dreamers who have no evidence (much less proof) of how things on this plant came to be as they are today.

Ok so basically, If I can get a pet old world monkey or bonobos and put it in time conveyor and see if it breeds with other bonobos or old world monkey and creates another human species, then. Have I became God yet?

Terror birds were such a cool creatures, sabertooth cats too but we still have big cats, we don't have terror birds, closest thing is the secretary bird. I wish those were still around.

The Great American Biotic Interchange
Why does that sound like the name of a near-future hyperloop train network?
Ladies and gentlemen, welcome aboard the GABI!

WRONG! The theory is that the continents were already one and then started drifting away, kind of like California is till this day.

1: 44. Its not a magma layer- the mantle is actually made of solid rock, with the asthenosphere being a fluid solid. Study your geology, Ted -. -
