The pictures below show fossils of the pakicetus and aetiocetus, ancestors of the modern gray whale. What do the placement of the nostrils show? (click on the image to make it bigger)

• evidence that they evolved over time from an earlier species adapting physical characteristics to what was best suited for their environment

• evidence that the species lived in different areas of Earth at the same time which required different physical characteristics to suit their environments

• evidence that they did not change over time and the physical characteristics of the species remained the same

• evidence that the species migrated to environments that were best suited for their physical characteristics
