If you "inch" the continents in this movie, and compare the age data of the extinctions to the land masses movement, you will see that a continental "enmassment" from drift and rotation corresponds closely to the extinction periods observed. The exception is the drift apart that is shown by the 65 million year period of the Cretaceous boundary. Now the reason given in the drift/extincion hypothesis is that the climate of the enlargening land mass becomes much drier and much colder/hotter during season change than before. It is clear however that the drift apart of the continents accompanied a large change in climate as well. ucmp.berkeley.edu Extinctions.. (which strangely appear at the hotter climatic periods.) 1. 488 million years ago — a series of mass extinctions at the Cambrian-Ordovician transition 2. 444 million years ago — at the Ordovician-Silurian 3. 360 million years ago — near the Devonian-Carboniferous transition 4. 251 million years ago — at the Permian-Triassic transition 5. 200 million years ago — at the Triassic-Jurassic transition (the Triassic-Jurassic extinction event) 6. 65 million years ago — at the Cretaceous-Paleogene transition (the K/T or Cretaceous-Tertiary extinction event) 7. 7.
