A  Records of glacial masses in the tropics indicate a worldwide ice age.

B  Modern-day species that evolved in isolation share a common ancestor.

C  Calculations of tidal forces show that this mechanism is sufficient to cause landmasses to move.

D  Rocks of varying ages found in mountain chains separated by the Atlantic Ocean indicate that they formed at different times in history.

E  Coal deposits that form in tropical swamps are absent from continents near the poles.
