Vestigial Structures

The fossil record provides evidence that organisms have changed over time.

Individual species disappear and reappear in the fossil record over time.

The fossil record provides evidence that all organisms developed at the same time.

Organisms in the fossil record are identical to living organisms.

Layer B contains the second-oldest fossils.

Layer A contains the most recently formed fossils

The fossils in layer B are older than those in layer D.

The fossils in layer D are the most recently formed

Two species that have the same DNA provide evidence that evolution has taken place.

Two species with very similar DNA likely evolved from a common ancestor.

Each living species has DNA made from different ingredients, showing that organisms have evolved.

DNA from related species is identical, providing evidence that all organisms have evolved in the same way.

the American black bear and the giant panda are most closely related

the giant panda and the red panda are most closely related

the red panda and the racoon are the most closely related

the giant panda and the racoon are most closely related

Species B is equally related to both species A and species C

Species B has a closer evolutionary relationship with species C than it does with species A

Species A has a closer evolutionary relationship with species B than it does with species C.

Species A has a closer evolutionary relationship with species C than it does with species B.
