Retake Quiz - Theory of Evolution

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.
  

• acquired traits through use and disuse.

• all eat the same type of food.

• descended from a common ancestor.

Darwin theorized that individuals having an advantage due to their traits or abilities will be more likely to survive and reproduce.  This theory is known as

• evolution
• speciation
• adaptation
• natural selection

What is survival of the fittest?

• It is where the fittest die out and therefore reproduce and pass on their genes
• It is where the fittest die out and therefore can't reproduce and pass on their genes
• It is where the fittest don't die out and therefore can't reproduce and pass on their genes
• It is where the fittest don't die out and therefore reproduce and pass on their genes

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

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number
  
• become extinct
  

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce? 

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals are better adapted to exist in their environment than others are. 
• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals tend to produce fewer offspring than others in the same environment. 

Lamarck’s ideas about evolution include the concept that differences among the traits of organisms arise as a result of

• continual increases in population size.
• the actions of organisms as they use or fail to use body structures.
• an unchanging local environment.
• the natural variations already present within the population of organisms.

The idea that the earth is millions of years old gave Darwin the idea that evolution of species could happen.

• John Hutton and Charles Lyell

• Thomas Malthus

• Alfred Russel Wallace

• John Baptiste LaMarck

What were Darwin's 4 major finding about evolution?

• Millions of species alive today arose from single original

  life form branching through a process known as speciation

• Evolutionary change was gradual

• Evolution is process that moves towards complexity and perfection

• Evolution did occur

• The primary mechanism for evolution is natural selection

• John Hutton

• Charles Lyell

• Alfred Russel Wallace

• John Baptiste LaMarck

• Thomas Malthus
