What is this an example of?

• Homologous structure

• Analogous structure

• Vestigial organs

• Functional adaption

Similarities in bone arrangements, like those in the picture, support the hypothesis that...

• these organisms are not well adapted

• these organisms share a common ancestor

• these organisms all share the exact DNA sequences

• these organisms are members of the same species

• 1 and 2

• 1 and 4

• 5 and 8

• 4 and 8

Which layer is the youngest?

• 2

• 3

• 4

Which species’ DNA is most similar to the DNA of the toothed whale? 

• Hippopotamus 
• Baleen Whale
• Grazing Mammals
• Camels

Which organisms are most likely to survive?

Which of the following is the collection of life's remains found in sedimentary rock?

• natural selection

• homologous structures

• biogeography

• the fossil record

When comparing the DNA of two different organisms, the less differences in the DNA base pairs the more-

• Closely related they are.

• Distantly related they are.

• It doesn't prove anything.

• They look alike.

Vestigial structures

• structures that perform a similar function but are not similar in origin

• remnants of once-important structures that have slowly lost all or most of their function

• features found in different organisms that share structural similarities but may have very different functions

• preserved remains of an organism

The picture shows a/an ___________

• homologous structure

• vestigial structure

• analogous structure
