How does the breakup of Pangaea influence the Mesozoic distribution and development of plants
and animals? What will be an ideal response?
Intercontinental migrations became increasingly difficult with the breakup of Pangaea. South
American and Australia became isolated island continents, and their faunas became quite
different from those elsewhere. This is especially evident in Australia with the species of
marsupial mammals, including kangaroos and wombats. Separation of populations by the
breakup of Pangaea led to increasing speciation.
