Question

Geological evidence indicates that two landmasses became separated by a deep ocean channel 45 million years ago and have been moving apart ever since. You are studying a group of organisms that is widespread as a native part of the biota on both of the landmasses. What can you conclude about the group's evolutionary history?

Answer 1

Well it seems like they can live on land or water, I think the tectonic plates had alot to do with it also.
