It took more than 3 billion years for life to spread from the oceans onto land. All organisms that lived on land evolved during the 550 million years that followed. How might this relatively rapid diversification of land species be explained? 

• the move to land environments led to FEWER changes in species over time

• the move to land environments led to MORE changes in species over time

• spreading to land DID NOT affect the amount of change in species over time

• the change in environments resulted in LOWER biodiversity

• It has limb bones like an amphibian.

• It is older than fish fossils.
