This one is a bit frightening:

As Insanity said, not much different:
http://en.wikipedia.org/wiki/Pangaea
The forming of supercontinents and their breaking up appears to have been cyclical through Earth's history. There may have been many others before Pangaea. The fourth-last supercontinent, called Columbia or Nuna, appears to have assembled in the period 2.0–1.8 Ga.[11][12] Columbia/Nuna broke up and the next supercontinent, Rodinia, formed from the accretion and assembly of its fragments. Rodinia lasted from about 1.1 billion years ago (Ga) until about 750 million years ago, but its exact configuration and geodynamic history are not nearly as well understood as those of the later supercontinents, Pannotia and Pangaea.

Any idea how long it takes for a significant tectonic change? I'm pretty damn ignorant on the topic. I'd be interested to see a map from 150,000 or so years ago (or whenever the best estimate is for the emergence of homo sapiens).
