Question

Diagram 1 shows the fossilized remains of the lower portion of a camel's leg. Each subsequent diagram shows the same portion of a camel's leg, but the diagrams are from progressively later time periods. Diagram 4 shows the most recent fossil.


These diagrams demonstrate
A.
that fossils show how species stay the same over time.
B.
that fossils can show how a species changes over time.
C.
that modern camels have more toes than earlier species of camels.
D.
that all living organisms have increased in size over time.

Answer 1

B. The sequence of fossils shows gradual changes in the camel's leg (for example, reduction/reshaping of toes) over time, so fossils can show how a species changes over time.
