Some organisms have features that have different functions, but similar structures. One example is the forelimb of humans, dogs, birds, and whales. What term best describes the relationship between these forelimbs?
They are homologous.
They are vestigial.
They are analogous.
They are embryological.

How do fossils support evolution?
Individual species disappear and reappear in the fossil record over time.
Organisms in the fossil record are identical to living organisms.
The fossil record provides evidence that all organisms developed at the same time.
The fossil record provides evidence that organisms have changed over time and share a common ancestor.
- 6. Multiple Choice

Which of the following statements gives the most likely explanation for the presence of two very similar species of squirrels living on opposite sides of the Grand Canyon?
One squirrel traveled across the canyon and started a new population on the other side.
Members of one single squirrel species were geographically separated by the formation of the canyon.
One squirrel traveled across the canyon and interbred with a different population on the other side.
Members of two different squirrel species migrated from two different places to opposite sides of the canyon.
- 9. Multiple Choice
The scientific theory of evolution is supported by different types of evidence. The diagram shows the skeletons of three different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?
It provides information about the organisms' habitats.
It provides information to determine the organisms' ages.
It shows possible common ancestry between organisms.
It shows possible chromosomal similarities between organisms.
- 10. Multiple Choice

chimpanzees and zebras
zebras and horses
- 11. Multiple Choice
When scientists compare the amino acid sequences for the red blood cell protein hemoglobin between various species, what can they determine about the evolutionary relationship between the species?
It can be determined how efficient hemoglobin is for different species.
It can determine relatedness between members of the same species.
It can provide evidence for common ancestor.
It can show which species evolved first.
