Questions from Late Oct. 2001:

Q: do you think the breakup of pangaea during the jurassic led to the extinction of some dinosaures and the evolution of other dinosaurs?
from pavel b, ottawa, ontario, canada; October 31, 2001

A: Yes, it undoubtably did. The breakup of Pangaea would have caused huge climate changes. For example, when Pangaea was intact, most of the world's land was interior desert; after the breakup, the climate was more moderate and there were fewer deserts. A major climate change like this would certainly be accompanied by a reshuffling of life forms (extinctions and new forms evolving).

from bern F., Edison, Nj, USA; October 29, 2001
