Question

Fossils of the same life form species have been found on continents that are now divided by oceans. In one to two sentences, explain how this could be possible if a supercontinent did not exist.(2 points)

Answer 1

The same species could have lived on different continents because temporary land connections or island chains (or lowered sea levels exposing continental shelves) allowed organisms to migrate between landmasses, or individuals could have dispersed across oceans by rafting on vegetation. These routes would let a species spread before the continents became isolated, leaving matching fossils.
