Natural Selection

Natural Selection is simply the logical result of  four features of living systems:

• 
  
  Variations- individuals from a population vary from one another.
• 
  
  Inheritance-parents pass their traits to their off springs genetically.
• 
  
   Selection- some variants reproduce more than others.                  
• 
  
  time-successful variations accumulate over many generations.

       

1. Through natural selection, genetic information( variation) was lost.
2. The long-fur dogs survive better in a cold environment, they are less able to survive in a warm environment.
3. A particular characteristic in the dogs population was selected for.
4. dogs are still dogs since the variation is withing the boundaries of kind.
