Evolution-Lifeforms/Landforms

Which of the following best describes how LAMARCK would explain giraffes with long necks?   

• A. Long-necked giraffes eat more grass than short necked giraffes so their necks grow longer. 
•  B. Natural variation in the population produces some longer and some shorter-necked giraffes and longer necked giraffes can reach food more easily.   
• C. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on.   
• D. Giraffes just started out with long necks and haven’t changed.

The natural differences between individuals of a species are referred to as  

• survival of the fittest
• natural variation
• adaptation
• natural selection 

When farmers select the largest hogs, the fastest horses, or the cows that produce the most milk for breeding it is called    

• A. natural selection 
• B. artificial selection 
• C. survival of the fittest 
• D. homologous variation

An inherited characteristic that increases an organism’s ability to survive and reproduce in its specific environment is called a(n).  

• A. homologous structure 
•  B.  vestigial organ 
• C.  adaptation 
•  D.  speciation

Rock pocket mice had light-colored coats that blended with the rocks and sandy soils of the Arizona desert.  A series of volcanic eruptions over a century caused the deposition of black-colored lava in the middle of the sandy region.  The population now consists of dark-colored mice that lived in lava deposits.  What is a reason for this change in coat color?

• The new coat color helps the mice reproduce easily.
• The new coat color helps avoid predators.
• The new coat color helps mice locate prey easily.
• The new coat color helps the mice mate easily. 

What will most likely occur to a species if the organisms are unable to adapt to their environment?

• cooperation  
• evolution 
• extinction 
• mutation 

Which BEST signifies the reason for extinction of various species?

• climatic events 
• natural selection
• survival of the fittest
• disease 

Which adaptation best suits the snow hare for its environment?

•   white fur
• big ears  
• small tail 
• blue eyes 

 Species that can adapt to changing environments, food sources, predators, etc. will survive to reproduce future generations.  This is called:

• Selectively adaptable
•  Naturally selective  
• Selectively permeable  
•  Natural selection

What type of event usually marks the end of a Geologic Era?

• A mass extinction

• A mass evolution

• A mass selection

• A mass destruction
