What comparative anatomy structure has a different form/structure but the same function?

• Analogous Structures

• Homologous Structures

• Vestigial Structures

What comparative anatomy structure is a result from left over traits that are no longer needed for survival and no longer serve a purpose?

• Analogous Structures

• Homologous Structures

• Vestigial Structures

Bone C: Shows the remnants of pelvic bones on a whale from when the whale used to be a land mammal. These bones no longer serve a function.

• Analogous Structure

• Homologous Structure

• Vestigial Structure

What type of comparative structure is this an example of?

• Analogous Structures

• Homologous Structures

• Vestigial Structures

Which of the following ideas is supported by Darwin’s observation of local variation among tortoises in the Galápagos Islands? 

• artificial selection
• adaptation
• acquired characteristics
• tendency towards perfection

Which statement is part of Darwin’s theory of evolution by natural selection? 

• More offspring are produced than can possibly survive.
• The organisms that are the fittest are always largest and strongest. 
• The number of offspring is not related to fitness.
• Acquired characteristics that are inherited are the cause of evolution.

By looking at the genes of some animals we can determine which living species are most closely related to each other. This also reveals which species most recently diverged from their common ancestor.

Based on the partial gene segments shown, which pair of animals are genetically most closely related and therefore most recently diverged from their common ancestor?

• Chimpanzee and Mouse

• Rat and Mouse

• Rat and Chimpanzee

Which rock layer contains the newest fossils?

• F
• E
• B
• C

Charles Darwin’s observation that finches of different species on the Galápagos Islands have many similar physical characteristics supports the hypothesis that these finches 
 

• have the ability to interbreed.
  have the ability to interbreed.
• acquired traits through use and disuse.
• all eat the same type of food.
• descended from a common ancestor.
