Evidence Evolution

Select all that apply to the image displayed.

• Has wings

• Has feathers

• Has bones

• Can fly

• An example of analogous structures

The fossils buried in layers near the surface tend to be younger than fossils in layers of rock well below the surface. This is an example of what type of evidende of evolution?

• Fossil record

• Molecular record

• Artificial selection

• Anatomical record

• exactly the same DNA sequences

• no proteins in common

• completely different DNA sequence

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures

• analogous structures

• homologous structures

• fossil structures

If modern organisms have a lot of homologous structures, what inference might paleontologists make about those organisms?

• They are reptiles

• One organism evolved from the other.

• The organisms have a common ancestor

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years

• Fossils show that some species have gone extinct

• Fossils show how life forms present today are different than those from the past

• Different sedimentary rock layers provide evidence for how the environment has changed over time

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram

• The organisms share a common ancestry.

• The organisms belong to the same genus.

• The organisms are native to the same geographic areas.

• The organisms will grow into anatomically similar adults.

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor

• Have very similar skeletal structures

• belong to the same species

• must range great distances to eat
