Let's rewind.
You've seen this: Pangea Some 200 million years ago.
But we're going way further back to 1.6 billion years ago, when big pieces of India, Antarctica and Ukraine were neighbors.
So were parts of Africa and South America, Canada and Australia.
This is the strange geography revealed by this brand new model of plate tectonics that was released at the end of last year.
It spans 1.8 billion years.
And of course, here at Howtown we ask, how do they know this?
You know, how did they come up with this model?
How do they know where all these continents were a billion years plus in the past?
So to find out, you and I are going to hitch a ride on two of these continents.
