While examining a layer of rock, a scientist found a fossil of a trilobite like the one shown below. The scientist knows that trilobites only lived during the Paleozoic era. The scientist finds fossilized remains of other species in the same rock layer as the trilobite. What can the scientist conclude about these other fossils?
The organisms that formed them must have evolved from trilobites.
The organisms that formed them likely also lived during the Paleozoic era.
The organisms that formed them likely went extinct before the Paleozoic era.
The organisms that formed them are still living in modern times.
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. What do these diagrams indicate?
that fossils can show how a species changes over time.
that modern camels have more toes than earlier species of camels.
that all living organisms have increased in size over time.
that fossils show how species stay the same over time.
