Natural Selection and Adaptations

 What is an organism?

• A single-celled life form

• A plant or animal

• A person, animal, or plant

• All of the above

What is an environment?

• The surrounding or conditions in which a person lives

  
  

• The surrounding or conditions in which an animal lives

  
  

•  The surrounding or conditions in which a plant lives

  
  

• All of the above

 What are genetic traits?

• Characteristics passed on from parents to offspring

  
  

• Characteristics determined by the environment

  
  

• Characteristics acquired during an organism's lifetime

•  Characteristics that only plants have

  
  

Who is famous for his work on natural selection?

• Charles Darwin

  
  

• Gregor Mendel

  
  

• Albert Einstein

  
  

• Isaac Newton

What is an adaptation?

• A body part, feature, or behavior that helps a living thing survive and function better in its environment

  
  

• A characteristic that is passed on from parents to offspring

  
  

•  A process by which humans choose a plant or animal to breed based on specific traits

  
  

• A process called Natural Selection

  
  

What is natural selection?

•  The process by which humans choose a plant or animal to breed based on specific traits

  
  

• The process whereby organisms better adapted to their environment tend to survive and produce more offspring

  
  

• The process of adapting to a new environment

  
  

•  The process of selectively breeding plants or animals

  
  

What did Charles Darwin study on the Galapagos Islands?

• Finches

• Lizards

• Deer mice

• Peacocks

 How do finches on the Galapagos Islands demonstrate natural selection?

•  They have developed distinctive beaks through the process of adaptation

  
  

• They have different colors and patterns on their feathers

• They have longer legs to climb better

• They have bigger and brighter tails

Which of the following is an example of natural selection?

•  Rat snakes with different colors living in different environments

  
  

•  Selectively breeding plants for specific traits

  
  

• Genetically modifying crops to be resistant to insects

• Birds with different beak shapes and sizes
